Extension roof ideas: 8 Roof Design Ideas for Extensions

Single storey extension ideas in the contemporary age are plentiful, and it can be hard to choose between all of the different options. However, with our comprehensive guide, we’ll definitely help you narrow down your choice so you can get the ball rolling with your dream extension!

Adding a single storey extension to your home is a brilliant way to create additional space, create an open-plan living arrangement or to connect with your garden in a more optimal fashion. They can completely transform uninspiring spaces into areas which every member of the family will simply adore living in. 

These extensions are also a far more cost-effective option that moving house. When it comes to single storeys, you really don’t have to break the bank in order to achieve amazing results. So many discerning homeowners are now opting for single storey additions to their home for not only the affordability, but the return on investment. 

If you ever choose to sell your home down the line, a single storey extension can add a lot of value to your property, increasing it’s overall sale price. Although there is a short-term upfront cost, the recouping on your investment in the long-term will be well-worth initial investment, providing the extension is built with the utmost quality and professionalism.

Speaking of which, if you’re looking to add a single storey extension to your home and live in the Birmingham or West Midlands area, get in touch with the West Midlands Home Improvements team today!  We’ve built and installed countless extensions across the region and we’d be more than happy to provide any assistance if you still have any idea queries after reading this blog.

Anyhoo, onto the blog…

Different Types Of Single Storey Extensions

If this is to be the most comprehensive and informative piece of content on the topic of single storeys, we need to start with basics. What types of single storey extensions are there to choose from? 

Side Return Extensions

A side return extension makes use of the space at the side of your home. It is often the most cost-effective single storey option, and creates a sizeable additional square or rectangular living space. Popular uses for this space include additional kitchen space or a conversion to an open plan kitchen. If built optimally, side returns can provide much more additional space than you would think! 

Rear Extensions

Rear extensions, as you can probably tell by the name, makes use of the space at the rear of your house. Depending on how much existing land you have to work with, the extension can be built in s square or rectangular shape. Great for open plan kitchens, open plan living spaces, a dining area or a utility room. For terraced homes, these extensions are a brilliant solution. 

Wrap Around Extensions

For the complete maximisation of additional space, a wrap-around extension is the way to go! This is where a side return and rear extension are combined, very well suited for semi-detached or detached properties. Wrap-arounds undoubtedly have the most dramatic impact on a home as you have the most additional space to utilise. They’re great for creating everything mentioned in the other two categories, and there may even be room for an extra toilet or bathroom. 

With any extension option, you’ll want to make sure that central rooms are still bathed in natural light, to avoid having any dimly lit areas during the daytime. We recommend strategically placing skylights, light wells, wall-to-wall windows or bi-folding doors in the extension plan. These options will provide the light you need for the central rooms, as well as make a striking design statement! 

Garage Conversions

Converting your garage is one of the most cost-effective ways of adding new living spaces to a home. Due to the structure of the room already existing, the budget required to transform the space is minimised and will go towards room improvements as opposed to construction. The major costs to consider are the removal of the garage door and the installation of new windows. 

Conservatories Or Orangeries

Of course, there’s the good ol’ conservatories or orangeries to consider, which come in many shapes and sizes, and can suit all budgets. uPVC conservatories are a popular option for UK homeowners as it’s a very easily mouldable and cost-effective material. Aluminium is the ultra-contemporary choice. More expensive than uPVC, but far more durable and aesthetically pleasing. 

Then there is the shape & style of the conservatory to consider. Gable-End, Victorian, Edwardian, Georgian, Lean-To, P-Shape, T-Shape or Glass Extensions are the main options to be thinking about. 

On the other hand, many opt for orangeries when it comes to single storey extensions. Due to the structures being comprised primarily of brick as opposed to glass, the living space can be comfortably used all year round.  

Garden Rooms

For those with excess garden space to utilise, a garden room may be the perfect option to choose. It should be noted that a garden room is far more than just a fancy shed. It can be your own private haven which many are currently using as home offices in the modern climate. The space can also be used as an entertainment centre, an annexe for a completely separate living space for family members, or any number of other uses. We’ve even seen homeowners use a garden room as a dance studio! 

What Type Of Roof Should You Choose For Your Extension? 

When planning any extension project, it’s easy to think about the use of the room and it’s aesthetics before considering the structural elements. But really, it should be the other way around! The roof is not only an integral structural element of an extension, but it also plays a big part in dictating the overall look of the additional living space. 

There are two main roofing options when it comes to single storey extensions. There’s the flat roof and the pitched roof.

The Flat Roof

Flat roofs are a common sight when it comes to single story constructions. Here are the pros and cons of this roofing type: 

Benefits: 

• Flat roofs are generally cheaper than pitched roofs so they’re a great option for those working within a strict budget. Less complicated structural engineering is involved and for the most part, flat roofs are comprised of cheaper materials
• They have a very modern look suiting those looking to achieve the most contemporary styling possible
• The flat roof is adept at incorporating very aesthetically pleasing design elements including skylights and light wells. These elements not only look the part but will flood the space with natural light
• Even though flat is in the name, these roofs have a slight pitch to allow rainwater to run off and not accumulate

Drawbacks: 

• Flat roofs will feature a lower ceiling giving your extension a smaller appearance
• The lifespan of a flat roof tends to be shorter than pitched options
• Flat options are not the most energy efficient design
• Depending on the material used, a flat roof can require more maintenance than a pitched roof

The Pitched Roof

Pitched roofs can be used for structures of all sizes, but they do tend to cost a bit more. Here are the pros and cons of this roofing type:

Benefits:

• A pitched roof tends to blend better with traditional-looking houses then flat options
• The higher ceilings will give more real and perceived height to a room making the space appear far larger
• Due to the increased weather resistance and the use of more durable materials, pitched roofs have longer life spans
• A pitched roof allows for more thermal insulation than a flat roof resulting in energy saving 

Drawbacks: 

• In terms of costs, a pitched roof is more expensive due to the increased material costs and the higher level of structural engineering required
• Another cost drawback is that pitched roods tend to take longer to install than flat roods. This will lead to an increase in labour costs and a longer build timeline for your extension

Different Roof Glazing Styles

There are a couple of roof accessories to also consider. If opting for a solid roof extension, roof lights or skylights are a great way to allow more natural light into the new space whilst adding a striking aesthetic as well.  

Then, there’s lanterns to consider which provide a stunning look to any room, but are slightly more costly. Traditional or contemporary lanterns are a great way of adding height to a flat roof extension. 

Finally, for the ultra contemporary look, structural glass roofs are becoming a more common sight across the country. They maximise natural light and are very popular on side return extensions in particular, but can be utilised in the other extension types as well. 

What Type Of Windows & Doors Should You Choose For A Single Storey Extension? 

Windows and doors are as equally impactful as a roof when it comes to the overall aesthetic of an extension. So, they require just as much thought and consideration. 

Bi-Folding or Swing & Slide Doors 

Bi-folding and sliding doors are a very popular choice for a single storey extension. A great way to merge the inside and outside living spaces seamlessly, these options have undoubtedly become one of the biggest trends in the home improvement world. Sliding doors feature fewer sight-lines and larger expanses of glass but do not allow the same amount of opening space as bifolds. 

Patio Doors

Patio Doors are another popular options as they suit both older and contemporary homes. They’re versatility doesn’t end there either, as patio doors look fantastic on both large and smaller extensions too! Patio options work by having at least one pane that slides whilst the other remans fixed. They usually come in two-pane, three-pane and four-pane options. 

French Doors 

French doors are the classic choice, bringing a chic feel to any home. These options provide a charming and elegant way to enter into your garden and come in a wide range of materials. Ideal for smaller extensions but can be fitted just as well in larger constructions. 

Feature Windows

As well as the usual window options including casement, sash cottage and tilt & turn, feature windows have become highly sought after in recent years. This is where very large panes of glass are incorporated into an extension’s design. They allow a room to be bathed in natural light and for you to enjoy the full width of your garden view from your interior. 

What Exterior Finishes Can You Choose For Your Single Storey Extension? 

The external appearance of your extension shouldn’t be forgotten about! There are plenty of options to choose from when it comes to an extension exterior. Obviously, this will partly be determined by your choice of windows and doors, and what colour they are. 

However, there are other aspects to think about including brickwork, rendering (the process of covering an exterior wall with cement, lime, acrylic, or some other kind of mixture. This protects exposed brick and other construction materials from erosion and cracking), cladding and tiling. 

All of which can come in numerous colours and shades, allowing you to really stamp your own individualism on your extension. You may wish for your extension to compliment the existing aesthetic of your home, or opt for a completely contrasting construction.  

Don’t Forget About Lighting When Designing Your Extension

A final element to consider, which many homeowners consider an afterthought, is lighting. Well thought-out lighting is key to ensuring that your new living space is optimal during the daytime, and after dusk. Some single storey extensions can look even more glamorous in the evening due to some stunning lighting options available. 

Up and down lights, ceiling pendents or chandelier lighting, wall lights, floor and table lamps, integrated spotlights, recessed wall lights, wire lighting, LED strip lighting or light fan combinations are some of the best options available. The right combination of these lighting elements can produce stunning results.

For a single-story residence, a flat roof over the extension can provide a contemporary look. Use this flat roof resource for finding the best design and cost for a well-constructed addition to your unique residence.

Roof Designs for Extensions

There are many flat roof designs to inspire your extension project, which you can find in books, magazines, and online. When done properly, a flat roof looks modern, in addition to being reliable. Here are some of the leading trends:

• Glass Roof Extensions – With glazing technology, panes are stronger, bigger, and more environmentally friendly than before. It can radically transform the look of your home and alleviate dark spaces, replacing them with sun pipes and an abundance of natural light.
• Bungalow with Balcony – Another idea is to create a balcony by extending the roof of your single-story home. Many homeowners are doing so and enjoy having more outdoor space with the balcony roof, which can increase property value and even include a garden.
• Slope Savvy – roofs are not completely flat; instead, they have a slight slope to enable easy drainage of rainwater. One design idea is to slope the roof more than the usual 1.5 degrees. Slope it to 10 degrees (it’s “flat” as long as it is less than 15 degrees) and slope upward to the garden for a more expansive view and a roomier feel inside.
• Long Overhang – Another conversion idea is to construct a deep overhang, rather than just sitting the roof’s edge on top of the wall it sits on. Add detailing to the overhang for the illusion of slenderness and a less boxy feel. The look is akin to horizontal and vertical planes.
• Roof Lantern – An orangery-style glazed roof lantern sits within a flat roof and, from the outside, looks as though the roof has timber and planting, which is aesthetically pleasing. The glazed lantern lets natural light flood in your home.

Before Deciding on Your Flat Roof Extension Design

There are obvious considerations to make before applying any of the new ideas presented above to your single-story or multiple-story house. Asking yourself the following questions will be helpful:

• Do you want an architect to design it?
• Does your builder have flat roof experience?
• What type of roofing material will you choose?
• Do you want roof access? If so, how will you access the roof?
• What roof color would you like?

Your answers to these questions may dictate your stylistic choices. We suggest you use a builder who has worked on flat roofs before to help safeguard against any structural issues with your idea.

In addition, many homeowners choose a roof hue that complements your house’s exterior color scheme for a more cohesive look. Another consideration relates to money.

Roof Extension Cost

You will likely have a budget for the project and, in this case, learning that a flat roof generally costs less than a pitched roof will be good news.

This is because a flat roof requires less structural engineering and can utilize less expensive materials than the pitched variety.

As for what price to expect, it can depend on several factors, such as:

• Location – A large city will have higher costs than a remote location.
• Accessibility – What is the height and is it easy to get to?
• Materials – The higher the quality of materials, the more you can expect to pay.
• Size – A small roof will be more affordable than a large roof.

You can expect to pay about $1,500-$2,000 USD per m2 for a single story extension, with variation depending on the four details listed above.

Meanwhile, an estimate for the build cost of a double story extension would be roughly double the single story quote. Also, add 10-15 percent for the architect, structural engineer, and other professional fees necessary for a quality build.

However, if you do not have a choice as to which option you get, you may have to install a pricier pitched roof. =”wpforms-“]

9000 9000 installation of a roof for an extension

In order for the house to have a more original appearance, additional building elements are often used – extensions that will allow you to spend leisure time or gather your family at a large dining table. An extension can be created at the stage of building a house or upon its completion. Also, very often a veranda, terrace or other type of extension is already used for houses that were built a long time ago. In this case, you will have to think about how to protect the additional room from the influences of nature, its vagaries in the form of snow or rain.

The roof of such a structure should adjoin the house, have a certain angle of inclination so that precipitation does not accumulate on its surface. For a long service life of the roof of the extension, you must carefully follow all the rules and conditions, choose the best material for the roof.

Types of roofs and types of roofs

A thoughtful exterior of a private house will create a pleasant impression both for the owner of the home and for his friends or neighbors, because the external perception of the house forms an opinion about its owner. In the ideal case, the design of the house and the extension should match each other, combine correctly with each other. In order for this to become possible, it is necessary to use a single roofing material, both for the house and for the extension to it. An exception to the rule will be glass extensions for a dining table with a view of the environment or a greenhouse. In this case, the roof should also have a transparent appearance, regardless of the house and its covering. It is necessary to understand the specifics of the words, to understand their essence, since the roof is the upper part of the house, a structure that has layers of thermal insulation and waterproofing. In turn, the roof is a decorative coating that protects the roof from atmospheric precipitation. The choice of roofing materials for an extension depends on several factors:

• The functional role of the room.
• Outbuilding architectures.
• Building materials used in building a house.
• roofing materials.
• Financial opportunities.

If it is not possible to use a single roofing material, then you need to think about how it will look externally, what is appropriate in this case and what is not. It is important to keep the house and the extension in the same style so that the extension does not seem superfluous. Ideally, an additional structure should emphasize the house, be its original decoration. If you think over the project well, you can create such an effect that it will seem as if the roof of a private house “flows” onto a terrace or veranda, thus forming one whole. Roof types:

• Flat.
• Slope (the name depends on the number of slopes)
• Single and multi-cascade.
• Domed and conical.
• Complex (broken, multi-gable, etc.)
• Ceiling and attic.

Composite roof is used only for extensions that must match the style of the house, such as classicism or gothic style. In general, a simple pitched roof is more popular for extensions, because it will be the best, practical and inexpensive option. A pitched roof can be built using various methods, but initially you need to determine:

• Structure of an additional building.
• Used roofing material.
• Roof features.
• What will be the layers of thermal insulation and waterproofing.
• Financial opportunities.

The choice of material for the roof of the extension

Before buying the first available roofing material, you need to look through their complete list, find out the advantages and disadvantages of each individual material taken. Having compared all the pros and cons, you can choose the best option that will be used for the extension, ideally if it is similar to the material used for the roof of the roof of the house. Previously, the choice of roofing materials was limited, but now in the 21st century the range is practically unlimited, neither flexibility, nor by color or other factors.

Popular roofing materials:

• Fastlock.
• Soft roof.
• All tiles.
• Slate.
• Decking or metal roofing.
• Expensive decorative roof coverings.

Things to consider when choosing a roof:

• Amount of materials required.
• Service life.
• The price of the material, the cost of its installation.
• Plasticity, flexibility.
• Weight and resistance to external factors.
• Fire safety.
• Color variation.

Roofing nuances

A simple option for an extension – a covered terrace or veranda. In this case, the main role is played by the foundation and the roof of the extension. The extension itself can be either closed or open, the main thing is that this is a place to relax, where there should be no cold and moisture. You need to determine the angle of inclination – in the optimal case, it should be 20-30 degrees, if less, then snow will accumulate on the surface of the roof, if more, then the roof will be subject to large wind loads. When constructing the truss system, all subtleties and nuances must be taken into account, boards and beams of sufficient thickness must be used. The rafters are fixed with self-tapping screws or anchor wedges (depending on the material to which they are attached). With the correct construction of the truss system, the roof should have a margin of safety that can withstand a hurricane or tornado, regardless of whether they happen in this region or not. If the extension is not residential and has a “cold” roof, then heaters will not be needed here. If you plan to build a large residential building, then you can use a gable roof, and the attic should have a triangular shape. Particular attention should be paid to thermal insulation and waterproofing, because cold and moisture are unacceptable here.

Steps for installing a roof for an extension

For example, we can take the simplest, but at the same time popular option for extensions – a shed roof with ordinary rafters and a slate roofing cake.

Stages:

• Calculations, development of drawings. At this stage, the angle of inclination of the roof is determined, it should be from 20 to 35 degrees.
• At the edge of the extension, we install a beam, the stop point of the roof structure. Further, every 0.8-1 meters we mark places for installing rafters. A special beam is fixed with anchor wedges to the lower beam and the upper harness. Then, the extreme rafters are placed on the beam, after which the rest are set along the lace to the previously marked points.
• Installation of waterproofing.
• Lathing assembly.
• Laying a layer of insulation between the rafters and the batten.
• Sew up the rafters with plywood or a wooden shield.
• Laying slate according to the technology prescribed in the instructions. The choice of material and type of roofing for a private house in our country is not an easy task, because the roof will need to withstand extreme climatic conditions. The roof must reliably protect the dwelling from the sun’s rays and heat, from gusty winds and precipitation, and severe frosts. Obviously, not only the warmth and comfort of a private household, but also its appearance directly depends on the correct choice of the roof structure and materials of execution. Therefore, it is not surprising that homeowners are looking not only for the quality and reliability of all roofing work, but also for the aesthetics of the structure, beauty or originality of execution. In order for the choice of the method of creating a roof to be as effective as possible, it is necessary to take into account the features of the architecture of the building, the materials for the construction of the building and the subsequent roof decking, as well as the climatic conditions in a particular region. It is about these features and factors influencing the choice of the type of roof that will be discussed in this publication.

  Strip foundation

  The foundation is made in the following cases:

  • for buildings of considerable mass;
  • the house has a basement, basement or underground garage;
  • heterogeneous soil.

  The foundation can be 200-300 mm below the freezing depth of the soil or shallow (depth of occurrence – 550-600 mm). For light extensions, the latter option is used as the most rational in terms of costs and technical characteristics.

  Important! The attached foundation should be one with it at the junction with the base of the house. It will not work to make a single monolith, but you can connect them together if you hammer metal rods into the old foundation and tie them with a reinforcing cage. Then the concrete is poured.

  Please note! The strip foundation must be poured in one step, and for this it is better to turn to professionals with the right equipment. Preparatory work can be done by hand.

  Benefits of polycarbonate porches

  Polycarbonate verandas are much cheaper to build than any other material. The weight of the structure is minimal, which allows the use of a columnar foundation, which can be made independently.

  Despite the fact that this lesson is quite difficult, you can still do all the construction work with your own hands.

  Polycarbonate Verandas offer the following benefits:

  • Creating an optimal microclimate at any time of the year.
  • Possibility to create different veranda designs.
  • Cutting is carried out independently using a conventional jigsaw or hacksaw.
  • Thermal insulation performance at the highest level.
  • Resistant to sunlight, precipitation, fungus, mold and corrosion.
  • They have a long service life and an affordable price.

  A veranda is a glazed structure attached to a house or built into it.

  Please note! Polycarbonate is an elastic material, which allows it to be used in a wide variety of design solutions.

  Post foundation

  Posts are built from concrete, brick or a combination of both. Here it should be borne in mind that the underground will be open or not insulated, although the problem is solved by installing a pick-up with additional insulation when laying communications.

  Poles are placed in 1.5 m increments, with obligatory installation at the corners. Their immersion depth is 500-600 mm. The underground part is coated with bitumen for waterproofing. It is advisable to connect the columns adjacent to the main foundation to it with the help of reinforcing bars hammered into concrete.

  Judging by the reviews and numerous articles, the extension to the house under the roof in most cases is made of frame, as it is the cheapest, and it is quite simple to build it with your own hands.

  What are the differences between verandas and terraces attached to a house

  A terrace and a veranda are different from each other. The first is always located outside the main building. The second one looks like a small building with a roof. But they are united by a common feature – both are additional buildings.

  Veranda has all the same functional parts as a residential building: doors, windows, walls, roof, even its own foundation.

  The location of the terrace is on an elevated area, has a fence. Simply put, this is an open area located on the street. The veranda and the main house have a common foundation. It can be attached in addition to the structure or together with it.

  “Open veranda” is a terrace, and nothing else.

  Frame extension

  They try to place the above-ground part of the foundation of the house and the extension at the same height, but for the veranda it can be made lower by connecting the transition with steps or a small staircase.

  A wooden floor is suitable for any type of foundation. For tape, it can be made of concrete.

  The foundation is laid around the entire perimeter of the framing of beams 150 mm high and 100 mm wide. You can use logs, which will be cheaper. At the corners they are connected by locks. Before this, waterproofing is laid from below from several layers of roofing material.

  For the floor joist and for the spikes of the uprights in the beams, grooves are made through 50 cm. Racks are inserted into them and fastened with nails. In places for windows, beams are horizontally fixed, on which a window sill will be installed.

  Racks are made according to the height of the room. If the roof is shed, they are installed at a higher height near the wall of the house to create a slope. In order for them to be located exactly vertically, jibs are temporarily nailed to them.

  A strapping is made from above, grooves are made in it for rafters, which are fastened with dowels or nails to a horizontal beam. The other side they rest on a wooden beam with a section of 100x89mm, fixed on the wall of the house with anchor bolts. The rafters are supposed to be attached to the Mauerlat, which is installed on top of the strapping. For small buildings, you can do without it.

  The roof of the extension must go under the roof of the main house.

  The rafters are stuffed with sheathing. It can be with gaps or solid, depending on the roofing material used.

  Logs are installed in the grooves of the bottom rail with a step of no more than 1 m. The quality of the floor depends on how they are fixed. Each lag is set by level. If the veranda is open, a slight slope is made from the house so that rainwater flows out.

  The floorboards are attached to the joists with self-tapping screws.

  The walls are built in two layers, with waterproofing and insulation between them. Outside, OSB, plywood, boards are used, after which they are finished with siding. Interior decoration is made with sheets of drywall or clapboard.

  The extension of the roof to the roof of the house can be made in the following way:

  • shed;
  • gable;
  • under a common roof;
  • annex with sloping roof.

  Types of terraces

  Terraces are divided into the following types:

  • Attached – built together with the main house. We need a foundation, desirable supports and binding to the building.
  • Free standing – installation takes place on a concrete base. The material of manufacture is wood, stone or brick.
  • Perimeter wrap – Requires high quality foundation and building reference.
  • Wooden – construction is possible without a foundation, its weight is very low, it is optimally combined with wooden buildings.
  • Brick or stone – expensive, long installation, does not require special care, has strength and durability.
  • Open – looks like a platform without walls and a roof. The flooring must be resistant to water and sunlight.
  • Semi-open – in addition to the frame, there is also a roof that serves as protection from atmospheric precipitation. There are no windows, but there are supports, which may look like a pillar, and a frame.
  • Closed – has a roof, walls and windows.
  • Covered – has a canopy and supports made of metal, with which the roof is held.
  • With railings – made of the same material as the main structure.

  A simple folk or rustic style should focus on rough materials, using stone and wood for construction.

  Each species has its own finish. The choice of building depends on the preferences of the owners of the house. But first, everything should be thought out and weighed.

  If the exterior of the house is made in high-tech style, then the veranda should be made just as high-tech: with large frameless windows.

  Shed roof

  The most economical option is the shed roof of an extension to the house with a longitudinal adjoining to it. Reviews speak in favor of this design, with the exception of design. You can find another, more effective option, if funds allow. The roof is located on the logs of the upper harness. If a decision is made not to touch the old roof, which is in good condition, one new slope is made.

  Buildings are not rigidly connected to each other. The extension is attached by creating a sliding joint with a longitudinal groove, providing a strong connection of the walls with the possibility of shrinkage. The problem is often the ingress of precipitation at the junction of the roof with the wall. To drain water, a corner or gutter made of galvanized sheet is equipped. With a sufficient slope, moisture will not get inside.

  The shed roof of an extension to a wooden house has characteristic features.

  1. The angle of inclination is not less than 10 0.
  2. The roof of the extension is brought under the roof of the house.
  3. The extension is subject to the same loads as the house. In addition, its roof is located below the main one, and most of the precipitation can fall on it, which makes it necessary to impose stringent requirements on strength and waterproofing for an additional structure.
  4. Externally, the roof of the extension should not look shabby, despite the simplicity of the form.

  Roof slope selection

  The slope is the angle of the roof slope in relation to the horizon line. As a rule, the slope angle is measured in degrees, but sometimes a percentage of the height of the roof to the span is used. For example, a 100% slope equals a 45 degree angle. All roofs according to the type of slope are divided into:

  • pitched;
  • flat.

  The slope of the roof is primarily required for the drainage of precipitation. If the slope angle is less than 1%, i.e. it is essentially not there, then the roof will constantly leak. In our country, such a choice of organizing the coverage of buildings is more suitable for utility, technical buildings. But foreign designers often offer roofs without a slope as an original design move that helps to stand out from other buildings on the street.

  When choosing the slope of the roof, it is considered that the maximum load on the surface from the fallen snow is achieved at an angle of 30 degrees. So that such a surface can self-clean, i.e. snow naturally rolled to the ground, it is necessary to organize the slope angle of the slopes at 45 degrees.

  In addition to the amount and intensity of precipitation, it is necessary to take into account the gusts of wind for each specific area. It is important to understand that with each increase in the roof slope by 20-30%, the level of wind load increases by 5 times. But even an extremely small slope of the roof is not an option in this situation, the wind can penetrate through the cracks in the ceilings and tear off the roof. As always, it is necessary to adhere to the “golden mean”. But only specialists from design bureaus who are able to take into account all the features of climatic conditions will be able to find it.

  In the public domain, on the Internet there are calculation formulas and graphs for the correct determination of the slope angle for each specific case. In short, the essence of the action is to calculate the ratio of the size of the ridge to half the width of the building. The required slope value is obtained after multiplying the found number by 100. From the point of view of the financial costs of constructing the roof, we can say that they increase with the increase in the value of the indicator found by the formula.

  It is important to understand that the initial cost is not a priority for those who would like to get not just an aesthetic coating for their home, but also a reliable, durable, safe and multifunctional roof structure. That is why all developers offer a pitched roofing option, as the most reliable, albeit more expensive (compared to a flat roof). But it must be said that the slope of the roof, among other things, is also determined by the building material.

  Gable roof

  This option is suitable for the construction of a complete heated building with an attic. An extension to a house with a gable roof is more complex. For its installation, roll beams (150×100 mm) are first installed, which are the basis of the future ceiling. They lie on the upper dressing in increments of no more than 70 cm, and then they are attached to the wall of the house. After the beams, a truss system is installed (beam 100×100 mm).

  View gallery

  The distance between them is the same as for the beams. A crate is nailed to the rafters with a step corresponding to the type of roofing material. The last step is the laying of the roof and the installation of drainage systems.

  Peculiarities of terrace construction

  Characteristic features of terrace construction are:

• will determine the location;
• find building materials that are likely to be needed in advance;
• select the form.

The first step is laying the foundation. Then proceed to the installation of the roof. Don’t forget about decor too.

Thanks to the large panoramic windows, the connection with nature will not be lost.

An interesting solution to the use of the yard space will be a terrace with a barbecue or barbecue. To do this, follow the following work plan:

• equip the base;
• install railing and roof;
• do the exterior trim.

Corner terrace surrounds part of the house. It adjoins closely to two walls located at the corners. It is an effective method for organizing outdoor recreation.

Two-level terraces are most often located at the exit to the courtyard or at the main entrance. It is possible to access them not only from the first floor, access is also available from the second, which is very convenient. Especially when too lazy to go down.

Sloping roof

This method is more expensive, but functionally better, since an additional room can be arranged under the roof. Due to this, you can save the area of ​​\u200b\u200bthe site that goes under housing. An extension to houses with a sloping roof does not always look beautiful. Most often they make a continuation of the roof of the main building. In terms of design, here you can change its shape.

See gallery

Reviews of sloping roofs are the most controversial, because sometimes the design is very complex, and it is difficult to choose the appropriate design.

The sloping and gable roofs of the extension to the house are being built using a similar technology. For a dilapidated structure, it is advisable to build a new roof on the house, which will become common to it and the extension. In this case, the structure will increase significantly in size.

View gallery

For the new roof of the house, the truss system is assembled on the ground in advance. Shields for the crate are also being prepared. As a result, the replacement will be made quickly and efficiently.

Interesting projects of verandas and terraces

DIY projects with photos of terraces to the house can be found on the Internet. These include the following styles:

• Modern – furniture and appliances are selected so that there is as much free space as possible. The terrace has an attractive and cozy look.
• Traditional – only pastel shades and a large number of decorative details are used. Furniture should be wooden and massive.
• Baroque – a huge number of accessories, luxury and pomposity. The floor must have a ceramic stove, all the details are expensive.
• Mediterranean – marine colors are used, especially relevant for a terrace located near a river or sea. Mandatory marine print and wicker furniture.
• Chalet – the flooring is a deck board, the furniture is massive, all lines are clear and straight.

Timber or log verandas look cozy and homely.

Verandas and terraces are not only decorative. They are complete rooms.

How to make a roof on an extension to a house from the end

outside the city limits, sometimes there is a problem with how to make an extension to the house. Either the family has increased, or the space wanted, or for some other reason. From an engineering point of view, the most reasonable solution in this case is not to build another separate house, but to make an extension to the existing one. It is here that the communications are connected, and the layout of the site will not require changes. In this case, builders must solve a very important task: how to join the roof of the extension and the house. At the same time, one wall will be common, the rest will have to be completed. The organization of the passage between the old and new parts of the house allows us to consider the extension as an added area. This will be discussed in our review.

Types of extensions – why functionality is important

An extension, depending on the desire of the owners, is assigned various functions. It can be a summer terrace or a kitchen, an additional warm room, a workshop or a garage. Some serve as a vestibule for the main house or have their own separate entrance. It can be located on the side of the main facade, on any end, or attached to the back wall. And in height, it is usually lower than the main house.

The annex has its own load-bearing frame, independent of the main building. And even adjacent walls can be separate. A rigid attachment of the extension to the house is not mandatory. But the junction of the two buildings must be closed from above from the flow of rainwater. To do this, they combine the roof of the extension with the main house.

The problem of joining the roof of an extension with the main house has many solutions, which depend on the shape and design of the main roof.

Various options available. Roofs are one-, two- and three-pitched. There are also more exotic situations, but they will not be considered here.

Shed roof of extension to the house

If the roof of the extension is shed, this is the simplest option. It should adjoin the wall of the main house. And its roof is somewhat higher, and it has no effect on design decisions. It is only important to show artistic taste and maintain the unity of the architectural style in the combination of the house and the extension.

The roof surface is one plane. It has a slight downward slope from the wall of the main house to the outside. The structural basis is a set of rafters – beams running from the wall of the main house to the extension wall farthest from it. The upper ends of the rafters are laid on a special horizontal beam attached to the wall of the house. The lower ends of the rafters are fixed on the beam of the new extension wall.

Do-it-yourself shed roof of the extension

In this case, the shed roof of the extension adjoins the wall of the house. The coating material of the new building should be laid right next to the wall of the house. Between it and the wall you need to lay a seal, which for greater effect should be smeared with sealant or clay. A more technological option using a special wall profile. Together with it, a sealant and a special sealant are sold in the kit. If the wall of the main house is concrete or brick, then the upper edge of the profile must be sunk into a specially grooved groove.

The roof of the extension must necessarily slope outwards. This is necessary for the flow of water in the summer, and for the snow to slide in the winter.

A sheathing is laid across the rafters across the entire width of the roof – a set of battens with a smaller cross-section than that of the rafters. The frequency of laying the sheathing is determined by the material of the roof covering – the size of the tiles, slate sheets or roofing iron sheets.

There is a constructive option when the roof of the extension starts from the lower edge of the roof of the main house.

Attaching the roof of an extension to the house

This is a simple option. Both roofs have different pitches, the main house has a steeper roof. Sheets or tiles covering the extension must be brought under the overhang of the roof of the main house. At the same time, the use of a wall profile with a seal does not interfere at all. This will keep the joint from leaking.

Docking of two roofs

Gable roof extension

A gable roof consists of two flat quadrangles that are connected at the top to a ridge beam and parted at the bottom.

Mounting the roof of the extension

These rectangles are attached to the wall of the main house at one end, the bottom edge rests on the walls of the extension. The basis of the rectangles are the rafters. At the top, the rafters of two planes are connected to the ridge beam, with their lower ends resting against the extension walls. A crate goes along the rafters, roofing material is laid on it.

How to attach the roof of the extension to the house

The roof of the extension is attached to the wall of the main house through the rafters closest to it. The abutment line is sealed in the same way as in the case of a shed roof. Since the roof boundary is sloping, the risk of leaks in this case is much lower than in the case of a pitched roof. But still, sealing the joint must be taken seriously.

Gable roof of an extension to the house

Tri-pitched roof is formed from three planes. One of them is an inclined triangle, the other two planes are formed either by trapezoids or triangles.

How to make a roof on an extension to a house

The gable shape is a tribute to the builder’s architectural fantasy, it does not bring practical benefits. The lower edges rest on the walls of the extension. A ridge beam runs from above. The assembly technology resembles the assembly of a gable roof.

Roof to house connection

The three-pitched roof adjoins the house along two lines. The docking requirements are the same as in the previous designs.

Sloped-roof extension

The roof of an extension can have two, three or more slopes. A multi-pitched structure in colloquial speech is also called a sloping roof, and sometimes a hipped roof.

How to make a roof for an extension to a house

If you build an extension with a pitched roof by yourself, then the design of the extension itself will be appropriate. Each break in the roof surface will go along its own rafter beam. The lower end of this beam rests on a pole. Extension walls are created between the pillars.

The technology of docking the roof of the extension with the wall of the house, in principle, does not depend on the number of its slopes. The most important task in this case is to protect the junction of the roof to the wall of the house from leaks. The most dangerous part in this sense is the horizontal. But in a multi-pitched roof it may not be at all, only inclined joints. They are less prone to leaks. But still, it is desirable to use a special profile with a sealing waterproof gasket.

Pitched roof extension

The structure of the roof differs from the three-pitched one in that there is no ridge beam. The surfaces that form the roof are in the form of triangles, their vertices converge at one point. The sides of neighboring triangles are connected. Their docking should be closed from above with a corner that protects against rainwater leaks.

Attaching the roof to the house

The extreme sides of the extreme triangles adjoin the wall of the main house. The requirements for the organization of the junction are the same as for other types.

Docking the roof of the extension with the roof of the house

There is a situation when the roof of the extension starts from the lower edge of the main roof, but, at the same time, they have different steepness. In this case, the roof of the new roof should be approximately 15-20 cm under the lower edge of the main one. The overhang of the main roof will protect the junction line from leaks. It is not required to connect the old and new roofs together, since each of them is fixed on its own crate.

How to extend the roof of the house to the outbuilding

Interesting designs that combine both buildings under one roof. Here, too, there may be options. The roof rafters of the main house are extended down, the roof is laid on the extension, and retaining pillars or extension walls are placed under the lower edge of the roof. But in this version, the extension will be low. This option is suitable for creating a small office space, such as a pantry.

How to make a house with an extension under one roof

It is quite possible to cover a house and an extension under one roof. New, longer rafters are mounted, their own crate and a new coating of the common roof for the house and the extension are laid on them. On the wall of the extension, a special frame made of good timber is laid under the rafters. In professional language, it is called “Mauerlat”. The upper ends of the rafters are laid and fixed on the “ridge run” beam. The lower ends of the rafters are fixed on one side of the Mauerlat.

After finishing work on the new roof, the old one can be dismantled. Thus, slightly raise the height of the ceiling.

Insulated roof

If the extension will serve as a living space, and even in cold weather, then the builder will have to decide on roof insulation. This is a more complex structure. The same design is used in the construction of two- and three-slope surfaces.

The insulated roof is completed with several layers of various materials. It is necessary to ensure that steam escapes from the room, to prevent water from leaking into the house, to create a heat-insulating layer, to provide these layers with mechanical protection both from above and from below. For each of these functions, the appropriate material is used.

Conclusion

Docking the roof of an extension is quite an affordable job for a skilled man. You just have to be careful and careful.

HOW TO CLOSE YOUR HOUSE

Roofing a house can easily turn into a complete weekend project, especially if you want to install a roof on a house that is not traditional in size or style.

Typically, roofing a house involves more than just adding shingles. It also requires careful and painstaking installation of all other components of the roofing system, including the underlayment, flashing and ridge.

It also requires understanding the different materials and how they work together to protect your home from the elements.

Materials needed for roofing the house

For the thorough work of installing a new roof, you will need the following basic materials:

• Roof-roof
• sealant Roof
• Self-adhesive waterproof lining
• Pileplet for the window and gutters
• Droppsy
• Bitumen or Bitumen-composure
• We are expected (No. 15 or No. 15)

add a traditional residential roof, so we choose asphalt or asphalt concrete as the main material for the exterior.

Asphalt or asphalt concrete materials are used in almost 80% of all residential roofs and typically have a predicted life of 20-25 years.

Tools needed to roof a house

Installing a new roof on a house can be a multi-day DIY project, so it’s important to gather all the tools ahead of time to speed up the completion of the project.

Here is a list of the tools you need to install a new roof on your home:

• Lean ladder
• Roof tether (*for safety*)
• Chalk
• Caulk gun (for adding roof sealant)
• Air hose or air compressor (for removing debris)
• Roof stapler/hammer
• Straight edge
• Tin shears
• Utility knife
• Circular saw
• Scaffolding and awning (to protect against falling materials)
• Work gloves

Of course, installing a new roof will be much easier if your building has a regular residential roof.

However, if you have a lot of roof structures, you will need the right tools to cut and shape the flashing for a perfect fit, so you may need tin shears and a circular saw.

10 steps to the roof of a house

The following guide describes 10 simple steps to add a roof to a regular building. Each emphasizes the need to integrate each roof layer into one comprehensive roofing system that can withstand the natural elements.

#1: Remove the old roof

The first step is perhaps the most obvious – you must clean the old roof before installing the new . Even if you are just about to install a new flashing and lining, you must first tear off the old roof.

When removing the outer layers, make sure you remove or drive in any nails you find – you don’t want those nails to cut into the new shingles you are about to install.

Also, since tearing off an old roof will obviously result in a lot of debris and debris, it is helpful to cover the building with a tarp to catch falling debris. You can also set up a trash bin nearby for the old materials you throw away.

# 2: Install underlayment

At this point you should have a completely clear roof of debris. If not, you can always use an air compressor to clean the surface.

The next step is to apply the self-adhesive backing to the bare roof. This lining must be waterproof as it will act as a barrier against wind, rain and snow. In fact, some building codes now dictate how much underlay should be applied and how much of the roof it should cover.

Since this underlay adheres very well to the structure of the building, you may notice that some of the old underlay still remains. If you can’t completely remove it all, that’s okay – just make sure the roof surface is as flat as possible.

#3: Coat the backing layer with tarbon paper

The next step is to apply another protective layer on top of the lining. You should use #15 or #13 felt paper (also known as “bituminous paper”), which can be found at any grocery store for home.

This felt has been specially treated with asphalt mix or asphalt mix to make it waterproof. As you work your way up the roof, make sure you overlap each successive layer by about 2 inches.

This overlay helps increase the watertightness of your roof by reducing the chance that strong winds can carry water between layers.

#4: Add Firmware

In order to make the new roof look as aesthetically pleasing as possible, most homeowners prefer to install gutter edges along the eaves.

You can simply nail this bar to keep it in place. This drip edge prevents materials from curling over the edge and gives your roof a nice finished look.

You can also illuminate the hollows of your roof, as this is where water tends to accumulate after heavy rain or heavy snowfall. In addition, flashing should be applied to any structures that protrude from the roof, such as chimneys or vents.

This plank provides extra reinforcement and protection from wind-driven rain, so every crease, opening and corner must be considered. Your roof is only as good as the weakest link in the chain, so you need to pay attention to the details.

# 5: Installing Starter Shingles

Roofers refer to the first shingles placed on the roof as “starter tiles.” “It is important to place and orient them correctly as they form the basis for the successive rows you will be laying.

Therefore, it is recommended to use the chalk lines as a guide. You should find the center of the roof at the top. From there, draw a vertical line with chalk. Using this line as a guide, you will then work to the left and right of it in the usual manner. With some types of roofs, you may prefer to work from left to right.

# 6: Install shingles

This is where you will begin laying the outer layer of your building’s roof.

When you are ready to lay the first row, you simply cut off the tabs from the three tabs and stick them on with self-adhesive glue. The stripes should be directed upwards along the eaves.

Most roofers will recommend that the first row have a small ledge with a drip edge. This protrusion must extend no more than ¼ inch beyond the edge of the dropper.

Also remember the principle of overlap. As you move along the roof, you need to make sure that each new layer overlaps the previous one a little.

#7: Nail on Layers

Roofs need to have maximum wind and rain protection, which of course means you’ll need to make sure your materials are firmly attached to the surface. You do this by simply nailing them.

Nail each layer of shingles directly over and flush with the starting layer.

The number of nails for each is up to you, but the standard number of nails is four per tile. In some exceptionally gusty or strong winds, up to six may be used.

If you need help getting your bearings right, you can draw horizontal lines across the roof with chalk. You must make sure that you lay one after the other in perfectly straight rows.

#8: Install additional firmware if needed

You can never be too careful when it comes to installing a new roof. You really need to make sure that every building or architectural curve is accounted for. Thus, this is where the dormer window needs to be applied.

A dormer is the entire structure protruding from the house, including the window. You will also need to do a brief inspection of the roof to find all the vents and stacks. Everything that sticks out will need to be covered with a protective salary.

# 9: Ridge cover

The ridge is the very top of the roof. In a traditional building, this ridge is very easy to find – it’s just the top where the two sloping sides of the roof meet. It is important to close the ridge for additional protection of the roof.

This step is often overlooked, but a perfectly straight ridge cap is essential to fully protect your roof.

#10: Cover open nails and remove debris.

This last step is actually the final cleaning step where you take care of all the little details. For example, you may find that some nails are still sticking out, so you need to hammer everything in and close any exposed nails. You should also consider sealing any exposed planks.

You will also likely have some trash and waste left over from all your hard work, so you should take all of these materials away. If there’s a trash can nearby, it might be easier to just put it right in the trash can than to worry about taking them down the stairs.

House Roofing Safety Precautions

It should be noted that every time you work on a roof, you need to take serious precautions – both for yourself and for everyone underground.

Rooftop falls are more common than you might think, especially if you are carrying heavy materials up and down stairs. This is why many people advise using a full fall protection kit.

In addition, since you work outdoors, there is always the risk of slipping and falling due to unexpectedly slippery areas on the roof. The type of footwear you wear is of great importance: it must provide good grip on the roof surface.

With that in mind, here are a few basic safety rules to keep in mind:

• Use a fall protection kit consisting of a harness, rope and hook.
• Wear shoes with rubber soles that can grip the roof surface
• Wear hard hats near the roof
• Use a ladder that has been tested for significant weight
• Extend the ladder more than 3 feet beyond the edge of the roof to make climbing and descending easier

In addition, the types of tools and materials you use are also important. The better tools you use, the less waste you will have, the less energy you will spend on the job and the less chance you will make a mistake.

Conclusions

As you can see, installing a new roof is a lot more than just borrowing a ladder, climbing onto an old roof and adding a few rows of shingles. Most importantly, you must consider the different layers of your roof and how they work together.

This is especially true if your roof has structures such as chimneys or vents.

Most roofing professionals will actually refer to the entire “roofing system” just to make it clear that the waterproof lining and metal flashing added during installation is just as important as the choice of the final outer layer you put on. on your building.

The good news is that if you pay close attention to the design and installation of your roof, your roof will last at least 20-25 years. Of course, it needs to be checked and repaired regularly after any major storms, but you will have a roofing system that can protect you and your family from rain, wind and winter storms.

The Complete Guide to Roofs | Building Construction

When it comes to roofing, there are variations that can make it difficult to choose the right one for your project. Follow this guide to get everything you need to know to choose the right roof for your home, whether you’re building from scratch, expanding, or renovating.

This complete guide covers structure, design, and cost, and provides advice for those who want to make or renovate an existing roof with their own hands.

Design choices

When it comes to roofing, you have a variety of designs to choose from, including traditional, flat, green, and curved. Follow this tip to understand the pros and cons of each structure to help you make the right decision.

When weighing your options, ask yourself the following questions:

• How much do you want to spend?
• How complex is your design?
• Do you want to be able to use / convert roof space at some point?

Proper design

The roof is one of the key exterior features of your home, and if you get it wrong, the entire project will suffer. This is where pitch comes in and it will depend on the style of the home you are building or renovating. Too cool, and the house will not only look weird, but you will have to pay more materials for this privilege.

Similarly, the lower the slope, the greater the volume of water collected and released on the slope, so you need to make sure that the flooring you choose can handle the amount of water you expect. When it comes to flat structures that aren’t actually flat, you need to think of a very shallow slope so that the water can run off and not accumulate on the roof.

The pitch is also vital if you are planning to transform the area created by the roof – the slope is too low and you will not be able to use the space efficiently.

A balance between looks and practicality matters here.

You have other design options when it comes to roof type:

• Shed: Has only one slope. Great for maximizing space on one side, possibly to improve visibility.
• Duopitch: Pitched roof consisting of two inclined planes that intersect at the top ridge with a gable at both ends
• Hip: Pitched construction with slopes on all four sides that meet at the corners to form hips; may or may not have a crest.
• Mansard: Variant with tent or peaked slope, in which each plane has a double slope. Popular real estate in France and the USA.

Planning Permit

If you want to build, for example, a new steep-roofed house that is taller than neighboring buildings, you are likely to face objections from local authorities. Department. Seek advice from your local authorities before applying to get an assessment of your plans from a local planning officer to get the best chance of a successful application.

For existing dwellings, you can make many changes and improvements in accordance with your Permitted Building Rights. Adding skylights, changing roofing, and adding skylights are improvements that do not normally require a planning permit and as long as certain restrictions are met. and conditions, you can usually convert an attic within the allowed development.

Always check with your local planning office to see if the proposed job is eligible for your authorized developmental benefit.

Cost

The level of design complexity when it comes to the roof will undoubtedly affect the cost. The simpler the shape, the cheaper the price. If you want to keep costs down, choose a roofing system that can be assembled quickly to reduce on-site worker time.

In some cases, it may be more economical to choose a roof structure that is more expensive initially if it allows you to easily (and relatively cheaply) convert the space into something usable in the future.

When it comes to roofing, again, everything will depend on the material you choose. Follow this guide for a breakdown of costs.

How to Build a Roof

Although relatively few DIYers will practice when it comes to this part of a project, it is important to understand how a roof is made, especially if you are managing a project and using your own deals.

Choosing a Roof Slate

This is a tricky choice given the options available and it’s worth asking yourself if you want your slate to be locally produced , and whether you want natural or masculine – tile . Depending on your preferences, the cost and service will be different.

Repairs

If you’re renovating, you’re likely to run into a number of common problems, from mispositioning, missing or broken tiles, to sagging slopes. While inspections often reveal defects that require urgent attention (to prevent leakage that could damage the structure of the property), the need for a complete roof replacement is relatively rare.

This how-to guide explains how to identify defects, the necessary repairs and their costs.

20 house extension ideas | House building

Looking for ideas to expand your home? If you are considering expanding your home, you will need to research what kind of extension you want to build. These 20 ideas will serve as design inspiration to help you create the best addition to your home and bring your project to life.

These home extension ideas below will give you advice on everything you need to think about before you decide to expand – from how much value an extension will add to how the extension will work with your existing home.

1. Reconfiguring Existing Space

When it comes to good home expansion ideas, existing space is often reconfigured to make the most of the new space. The reconfiguration will allow you to create an optimal layout to make the most of access, views, natural light and privacy.

Interior walls and doorways can be added or removed to achieve the space you need and to integrate any new extension so you can get real value out of it and use it. Consider the location of the entrance and central corridor, which should effectively lead to all the main rooms, and the relationship between key spaces, such as the proximity of the dining area to the kitchen.

Use our renewal cost calculator.

2. Consider a two-story extension

Building two floors instead of one is a great idea for those who want to get the best value for money with a house extension idea, as the average cost per square meter (m²) is reduced by stretching more expensive roofing and foundation elements over a larger area.

You can also build an additional floor on top of an existing one-story structure such as a garage (provided that the existing foundations and structure are sufficient).

3. Choose the right materials for your extension

Another great home extension idea is to choose a contrasting yet complementary style or make the extension look like it has always been there. The first is much easier to do well.

If you choose the latter, make sure you copy key design elements, roof pitch, materials and details like brickwork and even mortar color, otherwise your new addition will look wrong.

4. Modern kitchen – great idea for an extension

If you want to create a modern designer kitchen in your extension but don’t have the funds for a custom design, create your own using modular units combined with end panels. panels, countertops and other items purchased from other sources to recreate the same look.

Most commercial suppliers do not offer panels large enough to create large islands or floor-to-ceiling block groups to form a “appliance wall” with no obvious joints. You can overcome this by purchasing large sheets of MFC (Melamine Coated Chipboard) with matching or additional finishes from specialists like Timbmet, along with matching iron-on edge bands.

5. Add a conservatory or solarium

If you’re looking for a relatively inexpensive addition to your home, this is where a conservatory or solarium comes into its own. Smaller conservatories often don’t require a building permit , are exempt from the Building Regulations and are relatively inexpensive, making them one of the most popular home improvements.

However, the conservatory can have its drawbacks: it must be separated from the house by external doors to reduce energy losses, and it can be difficult to heat in winter and keep cool in summer.

A popular alternative is to build a solarium – an extension with large areas of glazing but with a conventional insulated roof and usually one insulated wall (especially the one facing the boundary). The space can be opened up to the rest of the house and the temperature can be more easily controlled.

6. Don’t forget ceiling space when considering your home extension ideas

even more spacious and impressive. An extension makes it possible to add this feature for a relatively small fee, either by digging to lower the floor level or by building up. In a two-story extension, this can result in a level division on the ground floor, which can add interest.

If the extension is under a pitched roof, it may be possible to create a vaulted ceiling that is open to the ridge. Instead of building a conventional flat ceiling with a void at the top, install insulation inside a pitched roof to create this feature.

When it comes to period homes, it can be especially difficult to find the right extension design to complement an existing property. One possible solution is to add the new space as a completely separate building in a pretty style – traditional or modern – and connect them with a fully glazed walkway.

The choice of structural glazing for the walkway will reduce its visual impact and preserve the character of the original building. This device is preferred by many environmentalists and can also work well in tying down existing heritage buildings.

8. Fireplaces: Energy Efficiency in Mind

With the increased focus on energy efficiency, many people are blocking open chimneys and vents or eliminating them from their expansion plans. However, there are two energy-saving options that still give the feel and comfort of a real fire and are suitable for any home extension idea.

Smokeless gas fires are 100% energy efficient and do not require a chimney or chimney: a catalytic converter cleans all harmful flue gases, producing only water and carbon dioxide. The design features traditional fireplaces and stoves, as well as modern models with holes in the wall.

The second option is an indoor wood burning stove connected to an internal air source to prevent drafts. They are very energy efficient and have some interesting modern design options.

eat outside during the warmer months, but it’s protected from too much sunlight or little summer rain.

You can choose a traditional option such as a loggia or porch, or opt for a more modern space located under a projecting flat roof supported by thin steel poles, possibly with trellis trellises.

10.

Choose pocket doors for the best of both worlds

When it comes to house extension design ideas, if you can’t decide whether to close a new extension with a wall or an open floor plan, consider about installing sliding pocket doors to get the best of both worlds. When closed, flush sliding doors can look like a wall, but when open, they can disappear into the wall, presenting a clear opening.

Pocket door systems are available on the shelf (try Em-B) or you can buy the chassis separately (try Häfele) and the doors will be made to your own design.

11. Make Sure Your Home Extension Idea Features Opaque glazing for privacy

Ensuring plenty of natural light is one of the key ingredients for successful extension design. border, consider using tinted glazing to take advantage of daylight, but no one can look in or out.

Traditional options include textured or colored glass and glass blocks, while more modern options include etched or sandblasted glass and colored glass.

Top Tips

• If you can’t exactly match a traditional home, don’t try . Modern contrast is a more honest solution in this case
• It’s all about the light of . The extension will take some of the light into your original rooms, so make sure it’s filled with glazing.
• Create element . Whether it’s a staircase, a fireplace, a kitchen island or something else

12. Make your lighting special

Top Tip

Independent control of each circuit with dimmer switches or smart switches with presets is important.

A well-thought-out lighting scheme will create a wonderful atmosphere in your new space, allowing you to use different combinations of schemes for different activities.

Along with ambient lighting to provide the main background lighting for daily activities, includes accent lighting in the form of directional spotlights, ceiling and bottom lights, wall lights, partitions (with hidden source), table lamps and standard lamps to create chiaroscuro , which is a key element of the atmosphere. Add decorative lamps, for example, above the kitchen island or dining table, since turns on lighting .

Lighting can really help zone an open plan space like this kitchen-dining room with the Boston NIQ1330 pendant light from Perrin Interiors Ltd (Image credit: Perrin Interiors)

extensions with glass walls, polished stone or concrete floors, and crisp, clean lines can look fantastic, but they can also create acoustic problems as sound bounces from one hard, flat surface to another. Problems like this need to be overcome by introducing soft sound-absorbing materials into the room.

However, rugs, curtains and upholstered furniture are not always appropriate – for example, in the dining room or in the kitchen. An alternative is to install acoustic panels of some form . They can be attached to walls as textured profiled panels such as wall art or as flat panels with any image of your choice.

14. Frame views from your home’s extension

Position window openings to create a better view and improve privacy by shielding any unsightly exterior features or neighboring properties. Options include overhangs bay windows and bay windows located at an angle, with one or both ledges designed to work as a flasher.

Think also about window shape and sill height – narrow, oblong windows can create great panoramic views or be designed to create a particular landscape view. Low-level windows can be effective for creating a view while you are sitting or lying in bed.

Window seats can be another useful accessory here.

15. Consider the idea of ​​adding a cantilever house

Cantilevers are a useful device for creating structural elements such as balconies, mezzanines or entire floors that protrude from the floor below and appear to be floating with no visible means of support.

16.Make the most of your new staircase

If you decide to use your new staircase in your expansion, consider making it a key design feature. Options include floating cantilever steps, open steps, glass or metal railings, gallery landings, wide turns and spirals. This is probably the best opportunity to create an interesting architectural element in the house.

17. Change the look of your home

Instead of building an extension to match your property’s existing architectural style, the project can be part of an overall redesign scheme that will completely transform the look of your home. This is a good method for adding character and value buildings that are bland, utilitarian, unfashionable, or that have been expanded without sympathy in the past.

You may be able to carry out renovation work under Permitted Building rights (no building permit required), but check with your local planning authority first.

18. Exposed oak beams

The vaulted ceiling with exposed oak beams is a great design element that adds instant character to a space – perfect for a kitchen, living room or master bedroom. The all oak framed addition is ideal for a country home such as a cottage, farmhouse, converted barn or arts and crafts home.

An economical option is to combine the basic oak framed roof structure (main rafters, collar, anchor beams, braces, ridge and purlins) with softwood rafters – the latter hidden behind drywall and insulation.

Oak framing extension can be enclosed in Structural Insulated Panels (SIP) or any other building system to ensure it meets Building Regs thermal efficiency standards.

Exposed rafters give this extension a more traditional rustic feel, designed by Roderick James Architects (Image credit: Roderick James Architects)

19. Bring natural light into your home. Extension idea

Bringing daylight into your extension from more than one direction to add multiple layers of light and shadow will greatly improve the quality of the space.

In addition to maximizing window and glass door openings, consider installing a row of ceiling lights, a skylight, or skylight (a row of windows set just below ceiling level and above eye level) to bring light from above. In addition to illuminating the floor plan of a large home, these ideas will also help address issues related to views and privacy.

20.Consider an extension

If the garden is large enough, an extension may well be a smarter and more manageable solution than extending an existing home. A garden building could provide additional play space, but would be much more exciting as a self-contained home that provides a kitchen, bedroom, and bathroom.

Home Extensions: 25 Things You Need to Know Before You Start

If you don’t want to move because you love your home and where it is, but you just need some extra square footage, then a home extension can transform a space, what you have and give you what you need.

Whether you’re looking to expand up, to the side, or to the side, there are some key things to know before starting your project, from legal and logistics to budgets and builders.

To help you navigate your home extension project, we’ve put together 25 things you need to know before you start building.

1. Do extensions add value?

For an extension to make economic sense, it must be ensured that the added value exceeds the cost of the project. This can be difficult to estimate, but searching for similar local properties and estimating their value can be a useful guide.

Be aware of the maximum cost in your area and be prepared to adjust your plans if necessary.

2. Home extensions must comply with building code

Even if an extension to your home can be built in accordance with the building code, the work must be approved by the building code.

Building codes set minimum requirements for:

• structural integrity
• fire safety
• energy efficiency
• waterproofing
• ventilation
• and other key aspects that ensure the safety of the building.

Most repairs are excluded from the Building Regulations, with the exception of window replacement, lining, and rewiring. However, with the exception of certain new buildings such as sheds, outbuildings and some conservatories, all new construction work, including conversions, must comply with the Rules.

Typical examples of work requiring approval:

• House additions
• Attic conversions
• Interior structural changes such as demolition of a load-bearing interior wall
• Installation of bathtubs, showers and toilets with new plumbing or sewers.
• Installing new heaters
• New chimneys or chimneys
• Modified openings for new windows

0450 3.Should I build as large an extension of the house as possible?

Hint: matching materials

If you want your extension to match the existing property, you need to find the right materials (sometimes easier said than done). One mismatch can stand out like a sore thumb.

Often expanders are only concerned with thinking about a project in square meters only, not in terms of what that size adds to the home. When it comes to extending a home, bigger isn’t always better, and there are often ways to create a feeling of more space without adding a large extension.

This is often achieved through thoughtful design of not only the new space, but also the existing one.

4. Choose the Right Builder for Your Home Extension

When it comes to designing your extensions, there are several options to choose from.

These include:

Ask friends, family, and neighbors for advice, and search the Internet for how-to references that have developed projects like the ones you hope to build.

The owners of this home were able to convert the barn and link it to their property under PD rights (Image credit: Dave Burton)

far exceed the U-values ​​and air tightness levels specified in the Building Regulations.

However, adding a thermally efficient extension to a poorly insulated house will not make it cheaper to operate at night, and you should aim to increase the efficiency of the main house while the builders are on site.

6. Construction of a house extension on or near the sewer

If your house extension will be built on or near the sewer, you will need to contact your water board before work begins. “You have to think carefully about the location of the collectors,” explains Jonathan Darndell of Milton Keynes Architectural. “If a common sewer (one that serves more than one property) is within 3m of your extension, then a development agreement with the local water authority will likely be required.”

This can be difficult and expensive, especially if a new sunroof is required or an existing one needs to be relocated.

7. Superstructure over a one-story superstructure

While superstructure over a one-story superstructure or garage may seem attractive, these structures may not be able to withstand the load.

There are options in which the old structure is not up to the mark: reinforce the existing shallow foundation; reinforce or bypass the existing one with a steel frame laid in new concrete piers; or demolish and rebuild. The latter option is often the most economical.

8. Service planning for a house extension

If you are expanding your kitchen, you will need to confirm the location of your units, stove and appliances before work begins so that electricity, ventilation and plumbing can be planned.

The same applies if you are building a two story extension and include a new bathroom or separate bathroom in the design.

9. Will your boiler be able to cope with the expansion of the house?

Adding an extension to the houses will increase the demand for existing hot water systems, which may not be able to keep up.

It is recommended to determine what a new extension will need to heat efficiently and take into account boiler capacity, radiator size, water heater size and reheat time.

10. Living on site can slow progress progress as the builders try to change your life.

If you are not prepared for the disruption, you should definitely consider looking for temporary accommodation (short-term rental, hotel or stay with family or friends).

11. Access Restriction Factor

If you live in a home with restricted access terraces, this can affect the options you have when designing an extension to your home. For example, you may not be able to use certain building methods, or you may need to arrange with your neighbors to temporarily remove fence panels or use their land for short-term storage.

12. Mixing old and new

How well the extra space fits in with the original property will no doubt affect the success of the project. Although there are no hard and fast rules, you will need to decide if you want your new home extension complemented or contrasted with the main house.

13.

Off-site construction can save time and money

glued laminated timber (CLT), oak framing, structural insulated panels (SIP) and wood framing are often well suited for home extension projects. As the name suggests, most of the work is done in an off-site factory and then the components are delivered to the site ready for installation.

14. Do I have to manage my own house extension project?

“I will always argue that the best person to oversee the extension you propose to use and propose is yourself,” says project manager Bob Branscombe. “No one knows a space or building better than you, and no one is more interested in getting it right.”

Managing any construction project requires a high level of patience, organization, problem solving and decision making skills. contractor or packaging company.

Before you start on an extension home, you must determine whether you will be required to pay a Community Infrastructure Fee (CIL). m² (even if they are built within the permitted development).

However, developer compensation may apply, as Jonathan Darndell of Milton Keynes Architectural explains: at least three years after completion.

“Before starting construction, it is recommended that you consult with your local council to determine if any CIL fees apply and how to file and claim damages.”

16. Understanding the Party Wall Law

Your neighbors cannot stop you from building up to or even on the boundary between your properties, even if it means doing so. access to their land is required (assuming you have planning permission to do so and there are no restrictive conditions).

The Party Wall Law allows you to work on or on your neighbors’ lands and buildings, formalizing agreements while protecting everyone’s interests. This is not a matter of planning or building control.

If an addition to your home involves digging or building a foundation within 3m of a boundary, a party wall or party wall structure, or digging a foundation within 6m of a boundary, the work will require you to comply with the Party Walls Act. In these cases, you may need a surveyor to act on your behalf. The law does not apply in Scotland.

17. Site insurance required

When building a house extension, you will need to insure the site with an A-rated insurer to cover the existing structure and new work until completion of the project.

Even if your builder has insurance, it’s important to check their paperwork as most of them have liability coverage which will require you to prove fault in the event of a claim, which can lead to lengthy legal battles. This may also not cover claims due to natural events such as fire, flood and hurricane damage.

If you leave the property during construction, you will need site or vacant building insurance, which is usually a minimum of six months. Always contact your existing insurance company to let them know about the work before you start.

18. Wildlife Planning Rules

Permitted mining rights are limited in Wildlife Areas. The policy lies in preventing the loss of the area’s character. So, if you’re thinking about adding a home, always contact your local conservationist first.

19. The privacy factor

Your choice of glazing can affect how private your home feels and how exposed you are to passers-by and your neighbors.

One solution might be to consider your edge treatments, which may need to be adapted for privacy while the built-in screens in your glazing provide privacy without spoiling the view.

Even if a building permit

is not required for a house extension, you cannot modify or even cut a tree that has a TPO without a building permit .

All trees in the protected area are protected by law and have TPO on them, provided that their trunk diameter exceeds 75 mm. Modifying a TPO protected tree is a felony and can result in significant fines, so be careful if you’re extending your home near a protected tree.

( MORE: Tree Preservation Order)

21. Don’t forget your contingency budget

A good opportunity to cover any unexpected expenses – starting work on an extension project can reveal problems with an existing home that need it. addressing, for example.

We recommend a contingency of 10-20%.

22. You probably cannot claim VAT exemption

Most home additions will be subject to VAT on labor and materials at the standard rate of 20%, especially if you use a contractor to complete the work. If you use local merchants who are not VAT registered, you can save 20% VAT on their labor, but you still have to pay VAT at the standard rate.

Certain expansion projects qualify for VAT exemption, such as works in listed buildings (zero rate), conversions to existing housing that change the number of units (5% reduced rate), and works in a building that has been vacant for at least two years (reduced rate 5%).

To take advantage of the VAT exemption if you are extending a listed building or renovating an unoccupied home, you must use a VAT registered developer – you cannot recover VAT yourself.

( MORE: VAT Refund)

23. You will need to notify the Building Supervisor of your addition to your home

You will need to submit either a Building Supervisory Notice or a full plan attachment to the Building Supervisor before starting any work. A building notice will allow work to begin quickly, but you will not have the protection that building control has approved on the project, and you must correct any work that does not meet Building Regs standards after review.

24.

Light entry needs to be controlled

While bringing more light into a home is often the desired outcome of an expansion project, uncontrolled light entry can create problems with solar power enhancement.

Designers should be aware of this when designing glazing elements in an extension and reduce the effect of solar energy to avoid the situation where, like poorly designed conservatories, the extra space can only be used for a small part of the year. Screen fabrics can also be used to reduce glare and light scattering.

25 How much glazing can I add to my house extension?

“Building Code Part L limits the total area of ​​glazed elements in an extension to a maximum of 25% of the extension floor area,” says Jason Orme, experienced installer and editorial director of H&R .

“This creates a problem, especially on small extensions. A small kitchen extension, perhaps adding 20 m² of space, could easily take up space with double folds – 4 m (W) x 1.8 m (H) = 7.2 m² or 36% of the floor area – and would therefore be rejected. by building control.

“There are several ways around this. First of all, you need to subtract the total area of ​​windows and doors that are lost in expansion from your extra amount. If this does not result in a reduction below 25%, then you will need to show that the new glazed extension can meet the energy efficiency standards achieved with an unglazed extension in other ways.

“If that still doesn’t help, you will need to order a SAP assessment to show that your glazed extension will not emit more CO2 than a fully compliant extension of the same size.”

The choice of roofing for an extension: which material is better

What kind of roof to choose for an extension to the house? This question often arises among those people who have conceived the organization of terraces, verandas, additional living rooms, summer kitchens, etc. We will understand the types of roofs, roofing and insulation in more detail.

Types of roofing roofs for an extension to the house

Extensions to the house appear most often when the owners want to increase the area, for example, to organize a terrace, veranda, recreation area, garage, etc. As soon as such an idea arises, the question arises of choosing a roof.

Regardless of what type of extension roof will be, it must have certain elements. These include:

• rafters, on which the main load of the roof is placed, and they also form slopes;
• Mauerlat, which helps to properly distribute the load from the truss structure to the walls of the building;
• ridge run, which serves to hold the upper ends of the rafters on itself.

Now directly about what kind of roof extensions are:

1. Single slope.
2. Gable.
3. Tri-slope.
4. Hip.
5. Half hip.

Let’s consider each of these types in more detail, highlight the main features, pros and cons.

Shed roof

Features:

• the design is the most popular among owners of country houses;
• is most often erected for non-residential areas, for example, for a veranda or terrace;
• if you use thermal insulation, then it is possible to build such a roof over the residential block in the house.

Benefits:

• it is possible to make a shed version for the extension by continuing the existing one, that is, an asymmetric roof will be obtained;
• simple version for erection;
• in terms of cost – this is the most budget option.

Weaknesses:

• is rarely used for living quarters because the attic space is rather small;
• it is necessary to make accurate and detailed calculations before building a shed roof, which will be a continuation of an existing roof.

Gable roof

Features:

• gable roof extensions are not very common;
• you can use this option for extensions from both the facade and the ends of the building;
• has several varieties: when it is wedged into the roof of the house from the side of the slope, when the roof of the extension is a continuation of the roof of the house, when one pediment adjoins the wall of the house.

Benefits:

• among the varieties of gable roofs, you can always choose the right option;
• such a roof at the extension looks very beautiful and aesthetically pleasing, the roof does not stand out from the general appearance of the house.

Weaknesses:

• less frequently used;
• is difficult to tie to the truss system of the main building.

Tri-pitched roof

Features:

• is a roof with three identical slopes;
• two of them form a triangle, while the others look like a trapezoid;
• are very well suited for the terraces of private houses.

Benefits:

• looks interesting and unusual;
• a vast attic space is obtained;
• , you can select the entrance area in the extension.

Weaknesses:

• asymmetric design makes the load on the walls uneven;
• so that the roof does not tip over, it is necessary to choose the location of the extension itself correctly;
• needs accurate calculations from a professional so that the gable roof is reliable and safe.

Hip roof

Features:

• popular and easily recognizable roofing;
• has four slopes: two are triangular and the other two are trapezoid.

Benefits:

• rigid construction that does not deform;
• practical roof in terms of rainfall;
• resists strong winds very well;
• eaves perfectly resist destruction.

Weaknesses:

• rather costly option in financial terms;
• only specialists can build it qualitatively;
• it turns out a small attic, since the roof is low;
• need skylights for light source.

Half hip roof

Features:

• are also called half-hip roofs of the Dutch version;
• slopes-hips (trapezoids) are shortened triangles;
• base – on the upper gable beam in the form of a trapezoid.

Benefits:

• the presence of an attic space that can be converted into a living space;
• the roof is well protected from precipitation and wind;
• construction is strong and durable;
• half hip roof has an interesting, attractive and unusual appearance.

Weaknesses:

• due to the design features, it is quite difficult to build it without the help of specialists and professionals;
• the construction takes a large amount of building material;
• the construction of such a roof is a laborious and long process.

How to choose roofing material for the roof of an extension (terraces, verandas)

It is very important for an extension to the house, or rather for the roof, to choose the right coating so that the structure is beautiful, safe and durable. Currently, there is a huge selection of roofing building materials. However, you need to know their features, positive and negative points, including for one or another type of roof.

Metal tile, Decking (with economy segment polymer coating: Polyester, Matte Polyester)

These materials are suitable for the following types of roofs:

• can be used for difficult roof types;
• is recommended for temporary buildings.

Features:

• economy options should be chosen especially carefully and from reliable manufacturers so that the service life is long;
• the cost may vary depending on which manufacturer is chosen and what characteristics the material has.

Advantages:

• a large number of colors will help customers choose the best option for the extension roof;
• installation complexity can be categorized as “medium”;
• affordability.

Disadvantages:

• service life ranges from 1 year to 25 years;
• low sound absorption;
• is not resistant to environmental influences (rain, wind, etc.).

Metal tile, Corrugated board (with premium polymer coating: Pural, Prisma, Purex, Granit, etc.)

Suitable for these types of roofs: and unusual shapes.

• optimal ratio of price and quality of this building material;
• compared to the economy option, metal tiles and corrugated board of the premium segment will last longer, as there is a thicker coating;
• the price again depends on what characteristics this type of metal tile and corrugated board has, as well as on who their manufacturers are (brand fame, etc. ).

Advantages:

• service life 25-50 years;
• well resist external natural factors;
• a large number of shapes and colors of the material;
• medium level of installation complexity.

Disadvantages:

• low sound insulation properties;
• good quality building material is high in cost.

Flexible bitumen shingles (sbs modifier and oxidized bitumen)

This type of roofing material can be advantageously suited for roofs with the following features:

• multi-tiered;
• multi-pitched;
• having the appearance of a tent;
• dome type of erection;
• hip and half hip.

Features:

• “flexible” tiles are most often made of bitumen;
• the price is affordable, but can be increased due to the fact that it will be necessary to additionally use OSB plywood flooring during construction.

Advantages:

• many shapes and colors;
• for any budget, you can choose a suitable “flexible” tile;
• during construction using this material, there is very little of its waste, which is an additional cost savings;
• tiles are light in weight;
• convenience and safety;
• ease of installation;
• spectacular and aesthetic appearance;
• high sound absorption;
• service life 25-50 years.

Disadvantages:

• resistance to (external) environmental influences cannot be called high.

Insulation of the roof of the extension (terraces, verandas)

If it is assumed that the extension to the house will be used as a living space, then care should be taken to insulate the roof. Penoplex can be used as a heater.

Penoplex

Features:

• “Penoplex” is the name of the trademark, and the building material itself refers to extruded polystyrene foam;
• excellent indicator of moisture absorption;
• can be used in the thermal range from minus 50 to plus 75 degrees Celsius;
• has a G-3 flammability category, which means a high level of ignition, but with a flame retardant coating, flammability is reduced.

Benefits:

• does not soak in water and does not absorb moisture;
• well endures heavy loads;
• is easy to use in construction, including processing;
• service life – at least 50 years.

Disadvantages:

• rather high cost;
• is destroyed by direct sunlight;
• additionally need to consider protection against rodents;
• is an active combustible substance.

So, the choice of the roof of the extension of the house must be taken responsibly, so that the roof is not only beautiful and original, but also safe, durable, warm.

How to join the roof of an extension and a house: architectural, constructive options

Owners of country houses and individual houses outside the city limits sometimes have a problem with how to make an extension to the house. Either the family has increased, or the space wanted, or for some other reason. From an engineering point of view, the most reasonable solution in this case is not to build another separate house, but to make an extension to the existing one. It is here that the communications are connected, and the layout of the site will not require changes. In this case, builders must solve a very important task: how to join the roof of the extension and the house. At the same time, one wall will be common, the rest will have to be completed. The organization of the passage between the old and new parts of the house allows us to consider the extension as an added area. This will be discussed in our review.

   Types of extensions – why functionality is important

   Depending on the desire of the owners, an extension is assigned various functions. It can be a summer terrace or a kitchen, an additional warm room, a workshop or a garage. Some serve as a vestibule for the main house or have their own separate entrance. It can be located on the side of the main facade, on any end, or attached to the back wall. And in height, it is usually lower than the main house.

   The annex has its own load-bearing frame, independent of the main building. And even adjacent walls can be separate. A rigid attachment of the extension to the house is not mandatory. But the junction of the two buildings must be closed from above from the flow of rainwater. To do this, they combine the roof of the extension with the main house.

   The problem of joining the roof of an extension with the main house has many solutions, which depend on the shape and design of the main roof.

   Various options available. Roofs are one-, two- and three-pitched. There are also more exotic situations, but they will not be considered here.

   Shed roof of extension to the house

   If the roof of the extension is shed, this is the simplest option. It should adjoin the wall of the main house. And its roof is somewhat higher, and it has no effect on design decisions. It is only important to show artistic taste and maintain the unity of the architectural style in the combination of the house and the extension.

   The roof surface is one plane. It has a slight downward slope from the wall of the main house to the outside. The structural basis is a set of rafters – beams running from the wall of the main house to the extension wall farthest from it. The upper ends of the rafters are laid on a special horizontal beam attached to the wall of the house. The lower ends of the rafters are fixed on the beam of the new extension wall.

   Do-it-yourself shed roof of the extension

   In this case, the shed roof of the extension adjoins the wall of the house. The coating material of the new building should be laid right next to the wall of the house. Between it and the wall you need to lay a seal, which for greater effect should be smeared with sealant or clay. A more technological option using a special wall profile. Together with it, a sealant and a special sealant are sold in the kit. If the wall of the main house is concrete or brick, then the upper edge of the profile must be sunk into a specially grooved groove.

   The roof of the extension must necessarily slope outwards. This is necessary for the flow of water in the summer, and for the snow to slide in the winter.

   A sheathing is laid across the rafters across the entire width of the roof – a set of battens with a smaller cross-section than that of the rafters. The frequency of laying the sheathing is determined by the material of the roof covering – the size of the tiles, slate sheets or roofing iron sheets.

   Docking of the roof of the extension with the roof of the house

   There is a constructive option when the roof of the extension starts from the lower edge of the roof of the main house.

   Attaching the roof of an extension to the house

   This is a simple option. Both roofs have different pitches, the main house has a steeper roof. Sheets or tiles covering the extension must be brought under the overhang of the roof of the main house. At the same time, the use of a wall profile with a seal does not interfere at all. This will keep the joint from leaking.

   Gable roof extension

   A gable roof consists of two flat quadrangles connected at the top to a ridge beam and parted at the bottom.

   Mounting the roof of the extension

   These rectangles are attached to the wall of the main house at one end, the bottom edge rests on the walls of the extension. The basis of the rectangles are the rafters. At the top, the rafters of two planes are connected to the ridge beam, with their lower ends resting against the extension walls. A crate goes along the rafters, roofing material is laid on it.

   How to attach the roof of the extension to the house

   The roof of the extension is attached to the wall of the main house through the rafters closest to it. The abutment line is sealed in the same way as in the case of a shed roof. Since the roof boundary is sloping, the risk of leaks in this case is much lower than in the case of a pitched roof. But still, sealing the joint must be taken seriously.

   Gable roof of an extension to the house

   Tri-pitched roof is formed from three planes. One of them is an inclined triangle, the other two planes are formed either by trapezoids or triangles.

   How to make a roof on an extension to a house

   The gable shape is a tribute to the builder’s architectural fantasy, it does not bring practical benefits. The lower edges rest on the walls of the extension. A ridge beam runs from above. The assembly technology resembles the assembly of a gable roof.

   Roof to house connection

   The three-pitched roof adjoins the house along two lines. The docking requirements are the same as in the previous designs.

   An extension to a house with a sloping roof

   The roof of an extension can have two, three or more pitches. A multi-pitched structure in colloquial speech is also called a sloping roof, and sometimes a hipped roof.

   How to make a roof for an extension to a house

   If you build an extension with a pitched roof by yourself, then the design of the extension itself will be appropriate. Each break in the roof surface will go along its own rafter beam. The lower end of this beam rests on a pole. Extension walls are created between the pillars.

   The technology of docking the roof of the extension with the wall of the house, in principle, does not depend on the number of its slopes. The most important task in this case is to protect the junction of the roof to the wall of the house from leaks. The most dangerous part in this sense is the horizontal. But in a multi-pitched roof it may not be at all, only inclined joints. They are less prone to leaks. But still, it is desirable to use a special profile with a sealing waterproof gasket.

   The structure of the roof differs from the three-pitched one in that there is no ridge beam. The surfaces that form the roof are in the form of triangles, their vertices converge at one point. The sides of neighboring triangles are connected. Their docking should be closed from above with a corner that protects against rainwater leaks.

   Attachment of the roof to the house

   The extreme sides of the extreme triangles adjoin the wall of the main house. The requirements for the organization of the junction are the same as for other types.

   Docking the roof of the extension with the roof of the house

   There is a situation when the roof of the extension starts from the lower edge of the main roof, but, at the same time, they have different steepness. In this case, the roof of the new roof should be approximately 15-20 cm under the lower edge of the main one. The overhang of the main roof will protect the junction line from leaks. It is not required to connect the old and new roofs together, since each of them is fixed on its own crate.

   How to extend the roof of the house to the outbuilding

   Interesting designs that combine both buildings under one roof. Here, too, there may be options. The roof rafters of the main house are extended down, the roof is laid on the extension, and retaining pillars or extension walls are placed under the lower edge of the roof. But in this version, the extension will be low. This option is suitable for creating a small office space, such as a pantry.

   How to make a house with an extension under one roof

   It is quite possible to cover a house and an extension under one roof. New, longer rafters are mounted, their own crate and a new coating of the common roof for the house and the extension are laid on them. On the wall of the extension, a special frame made of good timber is laid under the rafters. In professional language, it is called “Mauerlat”. The upper ends of the rafters are laid and fixed on the “ridge run” beam. The lower ends of the rafters are fixed on one side of the Mauerlat.

   After finishing work on the new roof, the old one can be dismantled. Thus, slightly raise the height of the ceiling.

   Insulated roof

   If the extension will serve as a living space, and even in cold weather, then the builder will have to decide on roof insulation. This is a more complex structure. The same design is used in the construction of two- and three-slope surfaces.

   The insulated roof is completed with several layers of various materials. It is necessary to ensure that steam escapes from the room, to prevent water from leaking into the house, to create a heat-insulating layer, to provide these layers with mechanical protection both from above and from below. For each of these functions, the appropriate material is used.

   Conclusion

   Docking the roof of an extension is quite an affordable job for a skilled man. You just have to be careful and careful.

   How to make an extension to the house with your own hands

   When a house is built and inhabited, it often turns out that its area is not enough for comfort. This may be due to a change in the composition of the family or to the expansion of the needs and desires of the owners of the dacha. One way or another, there is a need to expand and improve . The extension to the house solves this issue. It is important that it be made in the style of the whole house.

   Consider how to make an extension to the house with your own hands, simply and beautifully. For its construction use:

   • timber: the most attractive – rounded, with heat-insulating properties – glued;
   • moisture-resistant chipboard: used for frame buildings, with high heat and noise insulation;
   • brick: strong, durable;
   • foam blocks and aerated concrete: lightness, thermal insulation.

   How to make an extension to a wooden house from a bar

   Before starting construction, it is necessary to consider the purpose of the attached area . Usually they are equipped with a garage, workshop or bathroom. This dictates the number of windows, structural features and the consumption of building materials. The construction budget and the duration of the operation of the structure depend on the correct selection of building materials. The format of the walls should be determined: solid stone or wooden, frame, frame-panel.

   The foundation is laid similar to that on which a residential building stands. They need to be connected in a single layer. A simple solution would be to install a pile foundation , which is possible without being tied to an existing one.

   For example, a 200×200 mm beam can be used for the construction of additional premises. It is a heavy material with shrinkage. How to make sure that the wall does not move away from the house during shrinkage? First, the extension beam is attached to the wall beam of the house with a bracket. The final strengthening occurs after shrinkage.

   How to make an extension to a house from foam blocks

   A foam block extension fits well into a house built from almost any material. The main thing is that the building should not be dilapidated and with a solid foundation. An important point in attaching a foam block structure to a house is the so-called splicing. There are two docking options :

   • rigid : this option requires a freshly laid solid foundation that has already passed the settling period;
   • with expansion joint : a more economical and affordable way, while the foundation is laid columnar, pile-screw or tape.

   Roofing material used for insulation. Whatever the size of the additional area planned, a plan is needed to correctly calculate the required materials.

   Foam blocks can be laid by one person even without special skills. The process is simple and not long. The technical characteristics of foam blocks are the advantage of material: it does not burn , lightweight , therefore it gives minimal shrinkage, has a porous structure, is easy to cut, is durable in structure. It is convenient that you can use foam blocks on any soil, and with its lightness it is very durable.

   Frame extension to the house

   Frame technology is very popular in European countries, and now with us. Construction is carried out in two directions :

   • frame-frame : such works are used in a complex process;
   • frame-panel : the used panels are completely ready for installation, they have openings for windows and doors. The size of the panels must strictly correspond to the parameters of the foundation.

   Sip panels, which are characterized by high mechanical strength, can be used in the construction. Feature frame structures are its high thermal insulation performance . The rooms retain heat much longer, and you can assemble such a structure in summer and winter. In addition, it is easier to attach additional structures of a similar type to it.

   Finishing work can begin immediately after completion of work.

   Legal requirements

   Construction of additional structures requires proper documentation and compliance with laws of the corresponding direction. Even adding a porch to a house without permission can cause conflict with the authorities and, worse, a state of disrepair. Therefore, it is important to consider all ideas already at the design stage.

   The process of paperwork for the construction of an extension to an already finished house is one-time. Step-by-step instructions will help you go through all the stages of the legal path :

   1. First, get consent from the neighbors in writing.
   2. Order a ground survey for the area where you plan to build a new structure.
   3. Prepare an extension project.
   4. Arrange for an assessment of the condition of the house already built on the site.
   5. Validate your project by obtaining approval from all relevant government agencies: utilities, electricians, fire safety, a licensed construction company.
   6. Obtain a New Construction Permit from your local architectural office.
   7. When you have completed all construction work, take the object through all the services that allowed it to be installed. They accept the object and allow it to be used.
   8. Register the building in the cadastral service, in the tax office.
   9. Renew your utility contracts, which will now record area changes.

   It is easier to entrust the development of the project to the appropriate organizations in order to be sure of its correctness.

   How to make a foundation for an extension to a house

   The right foundation ensures the stability of the entire building . When laying it, materials, the planned load and the nature of the soil are taken into account. Sheds or light summer structures can do without a foundation.

   There are several types of base: screw, monolithic, columnar, tape. Any base must be waterproofed. Consider the last two options as the most common.

   Band

   A massive building made of heavy materials requires a solid foundation. This is the strip foundation. It is a closed strip passing under the load-bearing walls of housing.

   Pillar

   Perfect for veranda . Supports are mounted at the corners of the site. It can be a brick, a log, a metal profile. The pits dug under the racks are covered with sand, creating a pillow. The supports are fixed in the ground and poured with concrete. For complete solidification, 5-7 days are enough.

   Floor

   With a strip foundation, concrete screeds or a wooden floor are made. The bars are stacked in two layers. Moreover, the second layer overlaps the joints on the first. Edged boards are used for the subfloor, and moisture-resistant plywood is used for the finishing floor.

   Walls

   The most commonly used are foam concrete blocks, light and easy to install. The walls are often sheathed with siding, clapboard, OSB.
