House extension ideas are amongst the most sought-after of building projects for homeowners.

Get your house extension just right and you won’t just create a big open-plan room with space for dining and seating. Smart extension ideas can add more valuable space to your home and can increase the value of your property, if you decide to sell, too.

Below, we have gathered the best house extension ideas to suit all house design styles and sizes of homes, and a wide range of budgets, too. There are different material choices to consider, plus expert advice to help you make the right decision.

House extension ideas

These house extension ideas will inspire you to get started on your project. Remember when planning a kitchen extension, the key to success is to pick an extension style that either complements your home’s existing materials and period, or contrasts with it completely.

1. Consider extension ideas for small houses

Architectural practice Studio Hallett Ike’s ER Residence started as a small but well-proportioned one-bedroom flat in a Victorian terraced house. But thanks this clever home addition idea, the space was opened up into a two-bedroom apartment. 

‘The new dining area, above, provides an immediate visual link to the garden,’ says co-founder Madeleine Ike. ‘We kept the material palette simple, using raw and natural materials. Stained Douglas Fir joinery forms a bespoke dining bench that extends from the kitchen. We also designed the dining table which is made from blackened steel.’ 

Keeping the overarching palette warm, muted and minimal throughout helps to make the whole flat feel cohesive.

2. Be sympathetic to existing house styles

A ruined cattle shed seems an unlikely starting point for a new home but architect Will Gamble thought otherwise and his vision created The Parchment Works for his clients. ‘Initially the owners wanted to demolish the former parchment factory,’ says Will, ‘but I convinced them the ruins could be celebrated through a sympathetic intervention.’ 

Will’s design created ‘a building within a building’, where two lightweight volumes were inserted within the old walls. ‘I exposed the beams of the cattle shed, as well as steelwork in the new parts. The clean lines of the kitchen helped to juxtapose the uneven nature of the older structure making a contemporary intervention set within a historic context.

3. Extend the ceiling upwards

The owners of this elegant Victorian-era country house in Dorset enlisted the help of interior designer Emma Sims-Hilditch of Sims Hilditch to help them to envision a new kitchen extension idea for the property. ‘The answer was to preserve the original, grand parts of the house while opening up and rationalizing the secondary spaces that had been added later on,’ explains owner Sarah Ainsworth.  

The rear extension was replaced with a large open-plan kitchen idea, dining and seating area with a show-stopping roof lantern that brings in lots of light and ceiling clad in rough, whitewashed boards to add texture and improve the room’s acoustics.

4. Use natural materials for any home additions

Planning a home addition can be an opportunity to let materials shine. Oak is the star in this Somerset house which has been renovated by David Salisbury, replacing two smaller structures with one space that can be enjoyed all year round. A fully glazed garden room has been created that features a new chimney made using brick and stone to match existing materials. 

‘Our client wanted a rustic look so opted for natural, unfinished oak,’ says creative director Karen Bell. ‘This type of open-plan living room is perhaps our most popular request. Being able to combine the functionality of a kitchen extension, alongside a living room and dining room, we have captured the essence of modern living. ’

5. Maximize efficiency and sustainablity

As well as respecting the history of this Grade-II listed Cambridgeshire farmhouse, Mole Architects also made sure that sustainability was part of the process, following ‘passivhaus’ principles to maximize energy efficiency. As well as ticking the environmental boxes, the clients asked for a home that was at once both special and modest, using unfussy finishes that enhanced the older structures and complemented the new. 

Rescued from near dereliction, the property now boasts a garden room, kitchen and main bedroom all in buildings that adjoin the 17th-century cottage. The revitalized design has also created a new connection with the garden and offers beautiful views across the nearby water meadows.

6. Let light in

When designing your house extension, it’s important to think about how natural light will enter the space and move throughout the day. Light is a vital consideration for extensions – and glazed doors, windows and skylights can be game-changers.

Opting for a glass ceiling instead of a skylight will allow light to flood in, making the area feel bigger and brighter. But glass isn’t limited just to your ceiling ideas – adding a glass partition wall will not only create a slick design feature but will help to unite the space overall. 

7. Reunite with nature

(Image credit: David Butler)

Combining indoor and outdoor living is an integral trend, and should be taken into consideration when planning an extension for your home.

Architecture and design studio Levitate had to do some serious juggling to breathe new life into the tricky layout of this Victorian mid-terraced home in north London. The result is a striking zinc-clad rear extension that appears as a garden pavilion, and features a cantilevered structure with bifold doors that allow the extension to be opened up entirely onto the garden.  

Spencer Guy at Levitate illustrates how important it is to know where light is coming from and how it will change through the seasons: ‘Our client’s brief was for the space to be used comfortably during the day in summer and in the evening in winter. The analysis showed a glazed roof would work fine in summer through the use of shading devices but it was a challenge in winter without excessive heating. We redesigned the roof to include the characteristics of a conservatory but using smaller roof lights so more of the fabric could be insulated. The roof lights were still large, but they were standard products with proprietary opening systems, which made for a better functioning, more cost-effective solution.’ 

8. Don’t obstruct views out to the garden

(Image credit: Taran Wilkhu)

Don’t let a lack of space restrict your style – or block your view to the outdoors. Taking an ambitious approach to the design and fittings can result in a striking small kitchen idea that punches way above its weight.

To create a separation between the kitchen and dining areas without losing the views to the garden, architect Alex Michaelis installed a low wall. ‘It also gives a feeling of protection while sitting on the banquette, allowing it to run longer and seat more people.’ 

(Image credit: Dan Glasser)

With vision and careful planning a huge amount can be achieved. This house extension project started as a relatively simple rear extension and roof terrace but became much more radical. Mulroy Architects’ plans saw four storeys of staircase moved and a floor removed to create a dramatic double-height atrium which brings daylight and views into all levels.

10. Retain the existing structure, style and materials

By their nature extensions are not built in isolation. The design must consider the building they are connected to and also the environmental impact.

Napier Clarke Architects reclad the existing extension on this 1970s house in Buckinghamshire and returned it to its original brick form. As Steven Clarke says: ‘This creates a more contemporary home, which reflects the local vernacular and materials.

‘One of the key decisions for this house extension project was, should we knock down and start again, or work with what we have?’ said Steven Clarke from Napier Clarke Architects. ‘We believed we could work with the original house as a way of creating a highly sustainable project through the virtue of retaining the existing.’ 

Steven’s clients were keen to retain the existing structure if it was more cost effective, but they also recognized the sustainable benefits. Once the decision was made, the ground floor, first floor and roof were insulated to reduce thermal loss. All windows and doors were changed from single-glazed to double-glazed and the heating system was replaced.

Is it a good idea to extend your house?

It is certainly a good idea to extend your home. Smart extension ideas can add more valuable space to your home and can increase the value of your property, if you decide to sell, too – but do be mindful of costs.

‘Cost control starts from the outset, says architect Andrew Mulroy: ‘Try to keep as much of the existing structure as you can. This means that all areas of the house are fully utilized rather than some rooms being dark and redundant. Get regular cost checks on your design as it evolves so you can steer it back on track before going out to tender. This will allow you to understand where financial risks are and help avoid the temptation to change things on site, which is always more expensive.’

Looking for house extension ideas? If you are planning on extending your home, then you will need to research what kind of extension you want to build. These 20 ideas will provide loads of design inspiration to help you create the best addition for your home and to get your project off the ground.

For a comprehensive guide to costs, planning and what you need to know before starting an extension project, take a look at our beginner’s guide to building an extension. 

1. Reconfigure Your Existing Space During a House Extension

When it comes to good house extension ideas, the existing space is often reconfigured to make the most of the new space. The reconfiguration will allow you to establish the optimum layout to make the most of access, views, natural light and privacy.

Knocking down internal walls and or moving doorways to achieve the space you require and to integrate any new extension, to ensure you get real value and use from it. 

Consider the position of the entrance and central hallway design – which should lead efficiently to all main rooms – and the relationship between key spaces, such as the proximity of the dining area to the kitchen.

Key Tips

• If you can’t match a traditional home exactly, don’t try. A contemporary contrast is a more honest solution in this case
• It’s all about light. An extension will take away some of the light source to your original rooms, so make sure it is packed with glazing
• Create a feature. Whether it’s a striking staircase design, fireplace, kitchen island or something else

2.

Consider a Two-Storey Extension

Building two storeys rather than one is a great idea for those who are looking to achieve maximum value for money with their house extension idea, as the average cost per square metre (m²) is reduced by stretching the more expensive elements of roof and foundations over a larger area.

You could also build an extra storey over the top of an existing single-storey structure, such as a garage (providing the existing foundations and structure are adequate enough).

3. Choose the Right Materials for Your House Extension

Another great house extension idea is to choose either a contrasting but complementary style, or make the extension look like it has always been there. The former is much easier to pull off well.

If you decide on the latter, make sure you are matching materials and copy the key design elements, roof pitch and details like the brick bond and even the mortar colour, or your new addition will look wrong.

4. A Contemporary Kitchen is a Great House Extension Idea

If you are looking to create a contemporary  kitchen extension but don’t have the budget for a bespoke design, create your own using modular units, combined with end panels, worktops and other features sourced elsewhere to recreate the same look.

This kitchen was sourced online to keep the extension’s overall costs down. The on-trend timber kitchen – from Units Online –  was installed at a third of the original design quote. (Image credit: c/o Effie Dracou)

Most trade suppliers do not offer panels large enough to create big islands or floor-to-ceiling banks of units to form an ‘appliance wall’, without obvious joints. 

You can overcome this by buying large sheets of MFC (melamine-faced chipboard) in a matching or complementary finish from a specialist such as Timbmet  together with matching iron-on edging strips. Sliding metal timber unit doors to suit standard-size cupboard units are also available from CK Kitchens .

5. Add a Conservatory or Sunroom Extension

If you are looking for a relatively inexpensive house extension idea, then this is where the conservatory or sunroom comes into its own. Smaller conservatories often don’t require planning permission, are excluded from the Building Regulations and are fairly cost-effective, making them one of the most popular home improvements.

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

Adding a sunroom is a popular alternative. They are an extension with large areas of glazing, but with a conventional insulated roof and typically one insulated wall (particularly the one facing the boundary). The space can be open to the rest of the house, and the temperature can be controlled more easily.

6. Don’t Forget Ceiling Space When Considering Your House Extension Ideas

A difference in levels between the old dining room and the kitchen meant that this side return extension needed to be 3.8m. The wall was instead topped with glass to make the most of the quirky ceiling heights (Image credit: Simon Maxwell)

Tall ceilings can transform the way a room feels — larger rooms especially are made to feel even more spacious and impressive. An extension gives scope to add this feature for relatively little cost, either by digging down to lower the floor level, or by building up. In a two-storey extension this may result in a split-level on the first floor, which can add interest.

Where an extension is beneath a pitched roof, there may be the option to create a vaulted ceiling, open to the ridge. Instead of building a conventional flat ceiling with a void above, fit insulation within the pitched roof structure to create this feature.

When it comes to period homes, it can be especially difficult to find the right extension design to complement the existing property. One possible solution is to add the new space as an entirely separate building in a sympathetic style – either traditional or contemporary – and to join the two with a fully glazed walkway.

Choosing structural glazing for the walkway will reduce its visual impact and leave the original building’s character unaltered. This is a device favoured by many conservation officers and can work well in linking existing period buildings, too.

8. Fireplaces: Bear Energy Efficiency in Mind

With increasing emphasis on energy efficiency, many people are blocking up open chimney flues and air vents or excluding them from their extension plans. Yet there are two energy-efficient options that still give the feature and comfort of real flames and are fitting for any house extension idea.

Flueless gas fires are 100% energy efficient and require no chimney or flue: a catalytic converter cleans all harmful combustion gases, producing just water and carbon dioxide. Designs include traditional fireplaces and stoves, and contemporary hole-in-the-wall models.

The second choice is a room-sealed log burning stove, connected to an internal air source to prevent any draughts. They are highly energy efficient and there are some exciting modern design options.

9. Outdoor House Extension Ideas

Verandas and covered outdoor spaces provide somewhere to sit or eat outside during the warmer months, but are protected from either too much sunlight or light summer rainfall.

You could choose a traditional option, such as a loggia, or go more contemporary space, set beneath a projecting flat roof supported by slender steel posts, perhaps with an area of slatted sun louvres.

10. Choose Pocket Doors for the Best of Both Worlds

When it comes to your house extension design idea, if you can’t decide between enclosing a new extension with a wall or going open plan, consider fitting sliding pocket doors, giving you the best of both worlds. When closed, sliding flush doors can give the appearance of a wall, but when open they can disappear within the wall, presenting a clear opening.

Pocket door systems are available off the shelf (try Em-B ) or you can buy the running gear separately (try Häfele ) and have doors made up to suit your own design.

11. Make Sure Your House Extension Idea Features Obscured Glazing for Privacy

Introducing lots of natural light is one of the key ingredients in successful extension design. Where a potential new window opening will look out onto a neighbour, the street, a side alley or directly onto a boundary, consider using obscured glazing, so you get the benefit of daylight but without anyone being able to look in or out.

Traditional options include textured or stained glass and glass blocks, and more contemporary options include acid-etched or sand-blasted glass and coloured glass.

12. Make a Feature Out of Your Lighting

Top tip

Independent control of each circuit using dimmer switches or smart switches with preset options is essential.

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

As well as ambient lighting to provide basic background light for everyday activities, include accent lighting in the form of directional spotlights, uplights, downlights, wall washes, baffled (concealed source) lights, table lamps and standard lamps to create light and shade, which is key for atmosphere. Add decorative lamps, for instance, above a kitchen island or dining table as feature lighting.

13. The Best House Extension Ideas Manage Acoustics

Contemporary 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 reverberates from one solid flat surface to another. Such problems need to be overcome by introducing soft sound-absorbent materials into the room.

However, rugs, curtains and soft furniture are not always appropriate — in a dining or kitchen area, for instance. An alternative is to fit some form of acoustic panels. These can be fitted to the walls as textured profiled panels like wall art, or flat panels printed with any chosen image.

14. Frame the Views from Your House Extension

Position window openings to frame the best views and to improve privacy — by screening off any unsightly external features or neighbouring properties. Options include projecting bay windows and oriel windows set at an angle, with one or both reveals designed to act as a blinker.

Think about window styles including shape and the height of the cill — narrow elongated windows can create wonderful panoramic aspects, or be designed to frame a particular landscape view. Low-level windows can be effective at creating views when sitting or lying in bed.

Window seats can be another useful device here.

15. Consider a Cantilevered House Extension Idea

Cantilevering is a useful device for creating design features such as balconies, mezzanines or whole storeys that project out from the floor below and appear to float with no visible means of support.

16.

Make the Most of a New Staircase in an House Extension

If you decide to go for a new staircase design when extending, consider making it a key design feature. Options include floating cantilevered treads, open treads, glass or metal balustrading, galleried landings, sweeping curves and spirals. It is probably the best opportunity to create an exciting architectural feature in the home.

17. Give Your Home an Exterior Makeover

Instead of building an extension to match your property’s existing architectural style, the project can become part of an overall redesign scheme that completely transforms your home’s appearance. This is a good technique for adding character and value to buildings that are bland, utilitarian, unfashionable, or which have been extended unsympathetically in the past.

You might be able to undertake the remodelling work under Permitted Development rights (whereby planning permission is not required), but do check with your local planning authority first.

A vaulted ceiling with exposed oak beams makes a great design feature that gives a room instant character — ideal for a kitchen, sitting room or master bedroom. An entirely oak frame extension is ideally suited to a rustic-style property such as a cottage, farmhouse or a barn conversion, or an Arts & Crafts home.

A cost-effective option is to combine an oak frame principal roof structure (principal rafters, collar, tie beams, braces, ridge and purlins) with softwood rafters — the latter hidden behind plasterboard and insulation.

An oak frame extension can be encased within structural insulated panels (SIPs) or any other construction system to ensure it meets Building Regs’ standards of thermal efficiency.

19. Introduce Natural Light into Your House Extension Idea

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

As well as maximising window and glazed door openings, consider introducing a bank of rooflights, a roof lantern or a clerestory (a row of windows set just below ceiling level and above the eye level) to bring in light from above. 

In addition to bringing light deep into the floorplan of an extended home, these ideas will also help address issues regarding overlooking and privacy.

20. Consider an Annexe

Where the garden is large enough, an annexe might well prove a more sensible and manageable solution than extending the existing house. A garden building might provide additional games space, but would be much more exciting as self-sufficient accommodation, providing kitchen, bedroom and bathroom spaces.

House Extension Plans – Examples and Ideas

Choosing the floor plan is one of the most impactful decisions ahead of you when you’re building a home or adding a home extension [Extension Guide]. Your building plan affects everything from the budget you’re going to need to the overall feel of your future home. So, how do you choose the right house extension plans?

Site Specifics

First of all, look out for any restrictions that may apply to your block. Environmental concerns, historical value of certain areas, landscape preservation etc. can all complicate obtaining a planning permit and starting a big construction project. Additionally, the residential development code requires that your property “respects neighbourhood character”, which can also shut down some house extension plans from the get go.

The site itself can also throw you some curveballs. For example, if you intend to build a single-storey extension by cutting into the garden, removing tree roots and other obstacles can be quite costly and time-consuming. Also, soil surveys are necessary to determine what kind of structure your block can support, among other things.

Making the Most of It

Avoiding unnecessary complications is only part of the initial planning, though. Maximising the advantages of your location is, arguably, even more important. What kind of view can you get? Which side of the house gets the most sun? Finding the best places for windows can get a bit tricky, especially if you’re building from scratch, so it is recommended to discuss it with your builder in detail.

Energy efficiency is also an increasing priority in modern building design and it too starts with your house extension plans. Passive design is a term that encompasses a range of techniques that allow you to maximise the use of natural light and reduce energy consumption for climate control. At the planning stage it revolves primarily around orientation of your building plan, location of windows as well as taking into account any additional shading that you may need to keep some parts of your home cooler, especially during hot summer months.

Fitting In

Of course, the main goal of your construction project, be it a new home or a home extension, is creating a perfect space for you and your family. How many bedrooms do you need? How many bathrooms? What other rooms and areas would you and your family members want in your ideal home? Perhaps, you should include a study nook to work at home or an extra large garage if you have multiple cars. If you have younger children, they would likely need their own play area both inside and outside the house. And if you entertain guests often, a bigger space for parties might be in order.

Of course, the trick here is to not only find an optimal solution for your family’s current needs, but to future-proof your home as well. As your family grows or shrinks with your children growing up and moving out, your home would have to adapt as well. Planning for many years ahead will save you a lot of trouble with maintenance or big renovations down the line.

The Flow of Things

There are many different aspects of building a home for a comfortable living, including the materials you use, the appliances you have and the provisions you make for the future. However, one of the most essential ingredients of a perfect home [Step By Step Building Guide] is a floorplan that follows your daily routines and allows them to flow naturally. The general idea here is very straightforward – set up the dining area close to the kitchen to avoid carrying stacks of plates back and forth each time you have a meal, don’t place your stay anywhere near the entertainment area and so on. But beyond simple common sense ideas we all have our own ticks and idiosyncrasies and fine-tuning your home to follow your own lifestyle is a good way to improve your day-to-day life.

The easiest example here is the kitchen. Setting up your kitchen to follow your workflow not only makes it easier to cook all your favourite meals but also lets you use space much more efficiently. There are, of course, many different layouts you can use, but as a general rule of thumb your design should be based around the most commonly used parts of any kitchen – the fridge, the sink and the oven. Position them as a triangle for maximum accessibility with spaces between occupied by cabinets and work surfaces that you need. Include ample space for the pantry and your kitchen is ready to go!

Design Trends

The convergence of creativity and technology bring many exciting trends to home building. Here are 5 trends you may want to consider incorporating into your new house extension design…

1. Natural Light and Ventilation.

Good use of natural light and ventilation not only saves electricity, it can make your home feel more spacious. Rooms look bigger. Ceilings look higher. And more generally, things just look less cluttered.

This can easily be achieved through the placement of windows, the design of external doors, and the addition of natural lighting and ventilation features. See some examples on our services pages.

2. Blurring Inside With Outside.

Many people are taking natural light to the next level by blurring the line between inside and outside. This can be done by opening up a wall with large folding doors. Or it can be achieved by weather proofing a deck or courtyard. Ask your extension builder how you may be able to extend your living area by blurring inside with outside… and make the most of our magnificent Melbourne climate.

3. LED Lighting.

The most exciting technological breakthrough in lighting recently is definitely LED lights. They are bright, energy-efficient and compact. This gives you almost unlimited flexibility when it comes to designing lighting for any home.

Some people opt for the minimalistic appeal by hanging tiny lights from the ceiling. Others add drama by incorporating bold colours and unusual materials. Modern LED lights work well with both design styles.

4. Colour.

Although your choice of colours is almost limitless, there seems to be 2 main house extension design trends this year. One is bold and bright with a mix of tribal and retro colours. The other is subdued and peaceful with a mix of earthy and romantic shades. You’ll find examples on our facebook page.

5. Flexible Designs.

Gone are the days when every room was built for a purpose. The best designs today allow the owner to adjust the room for different purposes. This not only gives you better use of each space, it generally gives your home a more open and natural feel.

6. Bonus House Extension Design Trends Tip.

Knowing about design trends is important. But following them blindly can cost you a lot of money and leave you disappointed. Be sure to talk with your extension builder Melbourne before making up your mind about any particular trend. There is always more than one way of achieving the result you want.

 

Popular house extension plans ideas

Popular house extension plans have changed dramatically over the years as have the houses that we live in. We’ve moved from tiny post-war cottages… to fibro and brick combinations… to modern custom homes complete with media room and large outdoor entertaining area.

It’s great to gather home extension ideas by looking at lots of popular house extension plans – there are plenty of home extension ideas examples in this article.

But it’s best to start with a solid ‘base’ design. Head over to our services pages to have a flick through some popular house extension plans to gather some ideas. We have free house extension  ideas Australia for ground floor extensions and two storey extensions.

Before you rule a design in or out, sit down and talk with your extension builder. He’ll be able to show you what modifications are affordable. And when you’re better off starting with a totally different ‘base’ design.

The advice of a builder during the design stage is invaluable. And it will save you money and time.

 

Saving money with your design

While house extension design inclusions like premium floor coverings, bench-tops, tap-ware and lighting can add thousands to the price of your new home extension, there is something more fundamental that may affect the price.

In fact, just being aware of this little-known house extension design feature could save you tens of thousands of dollars without compromising the style and sophistication of your home. And it simply has to do with…

The shape of your house

Think of it this way: whether its a single storey extension, two storey extension or a complete knock down re-build, the simpler the external shape, the lower the cost to build.

But please don’t misunderstand. A more complicated shape is not more expensive because of added difficulty to build. It just requires more building material.

A house extension design with more angles will likely have a greater wall surface area. This will increase the number bricks needed to build the walls. It will increase the length of gutting and eaves. And it will usually also increase the framework, gyprock, cornices and other building materials.

A house extension design with a simple shape (e.g. rectangle) can retain the same floor area with a greatly decreased wall surface area. The savings can run into the tens of thousands.

This extra saving can often times be the difference between being able to afford a house extension or blowing the budget. Alternatively, this money can be re-budgeted to upgrade bathrooms or your kitchen.

So before you fall in love with a complicated architectural house extension design, check with your builder how you may achieve the same result with a slightly modified external shape. This little design secret together with some friendly professional know how could save you thousands on your next home extension design plans.

Should you use an architect or builder for my house extension plans?

Would you like to save thousands on your home extension? Here’s a valuable design tip…

I know it sounds counter-intuitive. But before you look for an architect to design your home, choose your builder.

Why?

Well, did you know 80% of architectural plans never come to fruition?

You see, an architect focuses on what a home will look like. The design. The problem is, they rarely factor in the house extension costs. So what you end up with is a design that can quickly become…

Very Expensive to Build

Think about it: architects are trained to be visionaries. They ‘live’ to create the ‘perfect custom home’. That’s what you pay them for. But, they are not always focused on the practicalities of building — how much extra time and money certain design elements may take.

And the reality is,

They get paid for the design they create whether you end up using it or not.

There is a way to fuse vision with the practicalities of building. With a few small modifications, you can often achieve the same ‘design result’ for a lot less money.

When you choose a design and build builder, you get the best of both worlds…

• A design that is beautiful and functional
• And a design that is affordable to build

Avoid getting sued

There is a little-known problem an increasing number of people are facing. And it has to do with one of the most exciting aspects of extending your home design.

When shopping around for a builder, it’s tempting to compare house extension plans and ask for quotes from different builders for the same plan. If your house extension plans was prepared by your architect, that’s usually fine. Although your architect owns the copyright, he will usually give you access to the plan through a ‘licence’. But more often than not, people take house extension plans from one builder and ask a different builder to quote on that plan.

In their Information Sheet G017v09 January 2012, the Australia Copyright Council goes as far as to say this:

“If you decide not to build from that plan, it is advisable not to show that plan to anyone you subsequently ask to draw a new plan for you. If the second person does see the earlier plan there may be an inference that that person has consciously or subconsciously copied original elements of the earlier plan.”

With architects and builders eager to protect their intellectual property, this can quickly escalate into a legal battle.

This is a tricky area that can cause you a lot of grief and wasted time and money.

30 Free House Extension Design Plans and Examples for 2019

When your home living space becomes cramped, you have two options. One option is to sell your current home, move out, and buy a new house. Or, you can instead, select from small house extensions designs for your next project. The latter will save you money and allow you to enjoy the place you already call home.

When you have a house extension project coming up, since buying a brand new place is on the pricey side, adding onto or finding the needed space within your existing home is often ideal. Whether you want to extend up into the attic or loft, open up existing rooms to rearrange your floor plans, or create more space off the back of the house, here are a few plans and examples from the expert home extension team at Diligent Development. They are free and solid just for you. Are you ready to get started?

Following are free house extension design plans and examples for 2019. Start by making a plan choosing whether you will expand up, out, or within your existing home, and let us guide you through the rest.

Make a Plan You Can Live With

Choose a Blueprint That Meets Your Additional Space Needs

Regardless of which direction you decide to expand, up, out, or to find and open up space within, you will need a plan to follow. The best way to achieve this is to sit down with an expert who can help you figure out which floor plan is best for adding the needed extra space onto your home. Begin by sharing all of your dreams and everything you have imagined about extending your home with someone who knows how to help you get it done, and then the knowledgeable and skilled building expert will help you draw up a realistic plan.

Be sure to set and stay within your house extensions cost budget as much as possible, expressing your desired and reasonable top-end price to be certain the contractors will be able to build within your price range using a house extension calculator. Be sure to ask about the small costs that are easy to forget about, such as materials used, inspection fees, rentals for tools, equipment, or hauling prices to discard demolition debris, and everything that will be involved including fixtures, paint, outlets, plumbing and absolutely everything no matter how much or how little it may seem to cost individually. Get ideas by browsing through our house extension ideas photo gallery.

Build up for More Spacious Living

Creating a living space or spare bedroom in an existing attic or loft is often the most feasible way to gain extra room in your house. You don’t have to worry about taking up much needed land on your property when you build up. Some important things to consider when extending your home upwards is to make sure the ceiling height has adequate clearance and that there is a stairwell access that is to code in case of a fire when you may need to safely exit the home in a hurry as well as a way to access the newly built loft extension from within your home. Attic or loft extensions can be done at a reasonable cost but do get expensive rather quickly when you start adding plumbing for an extra bathroom, raising the roof for needed head room, or installing dormers, windows, or skylights. Adding unique touches such as a skylight to the roof will help to save on lighting costs. You will find some great ideas by looking through a photo gallery of finished designs, and a qualified building contractor will be able to tell you if your desired attic or loft addition will fit within your budget.

Extend up to the Attic or Loft

Extend Your Walls to the Backyard to Gain Extra Living Space

One way to maximize natural lighting within your home and create a room where you can sit and read a book, dine, cook, or entertain, is to open up your wall to the backyard with an enclosed room extension.

Depending on your roominess needs, this extension could be seasonal, only used for entertainment or relaxation, or could be an entire enclosed permanent room added on.

Add an Extra Room onto the Back of Your House

An extra room on the back of your house is a nice way to enjoy your back yard without having to brave the elements of weather or contend with bugs and other unwanted outside elements.

Some rooms are seasonal with screens or canopies like a screened-in porch, a deck, or covered patio with a quaint gazebo feel. Others are able to be used year round, enclosed with windows and insulation as a four-season room, greenhouse, or a fully enclosed bedroom or sitting room with window bench seats and plenty of additional floor space.

However you decide to use your new room, extending toward the back of the house is a great option.

Bi-Fold Doors Open up or Close off Space

Sometimes all that is needed is more light to give the illusion of extra room. If the existing windows are blocking the maximum light you could be enjoying, it’s time to fix this. Installing bi-fold doors where your back wall used to be creates a way to open up your house entirely to the back yard or deck extension for entertaining when you need it. Just fold back the window-clad bi-fold door like an accordion, and slide to tuck out of the way. At the same time, bi-fold doors allow you to still be able to shut off the outside when necessary, allowing light to still flood into your home through the windows.

Find New Space Inside

Rearrange Your Indoor Floor Plan to Gain Extra Room

If what you really need is not more space as much as just better use of your current space, a new floor plan may be what you’re after. Three rooms tend to benefit most from redoing a floor plan to make better use of your rooms. The bedroom is a nice place to start. Turn a small bedroom into an on suite by knocking down non-weight bearing walls and rearranging them to serve a more roomy purpose. Another room that has heavy traffic on a daily basis is the kitchen. The bathroom is additionally a spot that will benefit from a new layout, though the existing plumbing may make it more challenging. In the kitchen, if you can open up a wall or move around counters, add an island and more storage, you will enjoy spending time in your newly remodeled place with a little less cramped quarters.

It’s amazing what even the smallest amount of extra room can do to improve the space quality of a small home. From smart loft conversions to slim side-return extensions there are plenty of options to improve the layout of a smaller property. Not only will smart extension ideas for small houses add much-needed space, the right renovation will add value too.

Visit our Project Planning channel for further advice and ideas for all your home renovation needs

A single-storey rear extension is often the most planning permission-friendly extension project, and can often be achieved under permitted development. Do keep in mind the balance between house and garden option, as swallowing up too much valuable garden space can reduce the properties value.

A simple side extension is also planner-friendly and can widen a narrow kitchen without stealing precious outdoor space. Side-returns are a common choice for terraced properties, which often have a half-width kitchen tacked onto the rear. This space might otherwise be wasted if not utilised by an extension.

Extension ideas for small houses

1. Double the downstairs floor plan

(Image credit: Future PLC/David Giles)

Small period properties can offer a slightly awkward layout, with narrow rooms and corridor-like hallways adjoining spaces. This compact design can increase how small the house feels. Adding a moderate open-plan extension across the back will open up the downstairs to make the whole house feel more generous. Just altering the downstairs layout will be enough to alter the feel of the whole house because it allows you to spend the most social time in the downstairs space. Limiting the extension to one storey keeps costs lower.

2. Create a relationship with the outside

(Image credit: Future PLC/Chris Snook)

A glass extension with retracting doors is the perfect way to create a seamless flow from indoors to an outside space, instantly preventing a small kitchen from feeling enclosed. This Edwardian house features a modern rear extension which allows the kitchen-dining area to seamlessly flow into the beautifully landscaped garden.

3. Add a small side extension

(Image credit: Future PLC/Alasdair MacIntosh)

Extending out to the side, even as little as a mere metre you can vastly improve the feel of a cramped kitchen. Especially when you choose a steel framed glass structure that will add a garden room feel, connecting the outside to the indoor space. The glass extension will flood the room with natural light, which will help to make a small kitchen space feel airy and more generous in size.

4. Give a small space more functionality

(Image credit: Future PLC/David Giles)

With a smart extension a small kitchen can become a more sizeable space for cooking, eating and socialising. Extending out to the permitted border allows adequate extra space to make the existing plot feel much bigger. Giving the one room a multifunctional aspect helps to make a small space feel more valuable in terms of how usable it becomes – you’re effectively getting three rooms for the price of one.

5. Elongate a narrow kitchen

(Image credit: Future PLC/Lizzie Orme)

Even the smallest of extensions has the power to totally transform the downstairs layout of a home. In this narrow kitchen an area extended beyond the existing kitchen allows extra space for the room to become more functional. Adding double doors, which open out onto a garden, allows for a seamless transition from indoor to outdoors, helping to enhance the sense of space.

6. Make use of existing space and keep it light

(Image credit: Future PLC/Simon Whitmore)

To help your small space feel bigger and brighter be mindful to keep the decor and design choices light enhancing. For any room extensions, look to add as many windows and glass aspects as you can, to ensure the room is filled with natural light.

‘If a budget is tight, your money is probably better spent improving the quality of the space that you already have,’ advises Nick Varey, Founder and Principal Architect, Studio Varey Architects . ‘Extending can be a costly endeavour, but a home can be vastly improved with more light and better internal layouts. Look to replace rear facing windows at ground floor with larger doors to bring in more light. Also removing internal walls to create more generous open-planned areas will give the feel of a larger home, at a reduced cost.’

7. Use the side return to your advantage

(Image credit: Future PLC/Veronica Rodriguez)

A simple side extension is the ideal way to widen a narrow kitchen without stealing precious outdoor space – because the space is otherwise redundant. ‘Side-returns are a common choice for terraced properties, which often have a half-width kitchen tacked onto the rear,’ says Lisa Morton at Vale Garden Houses. Always check planning permission, as side extensions can often be less forgiving than rear extensions when it comes to granted permission, due to the space being closer to the boundary walls.

8. Build upwards

(Image credit: Future PLC/Simon Whitmore)

In a small home you may not have the luxury to extend out into the grounds, it can therefore be best to work upwards. Maximise space by using the attic to add valuable extra living space. Loft extensions are one of the most popular solutions for all homes when it comes to adding more room, but particularly smaller properties.

9. Let the light in with glass panels

(Image credit: Future PLC/Colin Poole)

By installing glass panels and sliding doors for a space that opens up completely to the garden beyond the space will instantly feel a gained sense of space. This smart extension doesn’t go out further into the garden, it uses the space vertically to flood the room and incorporate the garden.

Pick and position wall and base units by thinking about the outside space too. In this kitchen the honeyed tones cabinetry helps to draw the eye up and out, while the lower cupboards are grounding a darker shade. All the design aspects work in tandem to open up the space, without having to make a larger footprint for extending. A high traffic throughway will need a hardwearing floor so choose a durable dark-tiled version.

10. Convert the garage

(Image credit: Future PLC/David Giles)

In a small home all space is premium. If you don’t use your garage for its intended purpose, which many of us don’t, then it’s a wasted opportunity to create more liveable rooms. A standard sized garage can be comfortably transformed into an extra bedroom and ensuite or extended kitchen space.

Planning Portal advises, ‘Planning permission is not usually required, providing the work is internal and does not involve enlarging the building.’

‘If your intention is to convert a garage into a separate house (regardless of who will occupy it), then planning permission may be required no matter what work is involved. We advise that you discuss such proposals with your local planning authority to ensure that any work you do is lawful and correctly permissioned.’

What are the best rooms to extend in a small house?

What are the best rooms to extend in a small home to maximise the space? ‘In small homes, every bit of space is vitally important’ says Nick Varey at Studio Varey Architects. ‘If the small home has external space to the rear that can be extended into. This is going to be your best opportunity to create a more generous internal layout. In this instance, extending the living space is going to bring about the greatest improvement in the quality and feel of the home; particularly with our adapting work / home lifestyles, which now see more people than ever working from home.’

If extending into a garden isn’t an option (with a flat or apartment, for example), then it is vital to seek out wasted and under-utilised spaces so you can convert them into more functional areas of your home’ Nick advises. ‘When working on small homes, we focus on two primary spaces – creating a generous open-planned kitchen/living/dining area and a decent sized bedroom. To maximise these areas, we look to ‘steal’ space from bathrooms that are often more generous than they need to be in small homes, as well as corridors.’

How can you add space on a budget?

‘If you own a house, then the cheapest area to extend into is going to be the existing roof space’ says Nick, provided the head height is good. ‘This is an area of the property that is useable but often not maximised. If the head height is there, you can turn this space into a functional room with little more than loft insulation, a flooring upgrade, a few roof lights and decoration! If there isn’t enough head height, consider extending to the rear of the roof with a mansard, pod addition or dormer.’

How much does a small extension cost?

There are many factors to consider when looking to extend your property that can impact the cost of works. Nick tells Ideal Home, ‘When advising clients early on, we provide guide estimate prices based on the cost per square foot of recently completed projects. A good ball park for the cost of a quality extension in e.g. London, is to budget somewhere in the region of £250 – £350 per square foot.’

Projects of extensions to the house in plain language

Many owners of country houses and cottages from time to time carry out redevelopment of plots with their own hands. But sometimes you have to touch the house. If it needs to be expanded, then an extension is an ideal option to increase the usable area. At the same time, it can perform completely different functions and be located not only at the main entrance. Projects of extensions are developed taking into account the peculiarities of their operation.

Building types

Usually the following types of buildings are attached to the house:

1. Veranda is a summer room that will allow the owner of the house to spend time in nature, but at the same time with comfort. Such extensions are used mainly in the warm season. But at the request of the owner, the building can be insulated, equipped with windows and used in winter. Verandas are built from any material, including brick, foam blocks and wood.
2. Boiler room. If the cottage was originally planned as a summer building, then it may not provide a place for a boiler or column. In this case, it is necessary to complete the room and install heating equipment there. Fire safety standards impose increased requirements on such buildings. For example, the material for them must be used exclusively non-hot, such as bricks or blocks.
3. Bathroom. Such an extension is mainly used in villages and cottages that are not equipped with a bathroom and toilet. In this case, the room has to be attached in order to increase comfort. Depending on the material of the main building, the extension can be made of timber, brick or blocks.
4. Living quarters are being completed in order to increase the area of ​​the house and are used as an additional room. Sometimes the dimensions of such an extension may exceed the dimensions of the main building. Often they are used in the restoration of very old buildings with a small usable area. The building material for such a room is mainly brick or blocks, less often a wooden beam.
5. The garage is attached to the house, either to save the budget due to a common wall, or to heat the room for the car from the heating system in the house. For the construction of a garage, blocks and bricks are most often used.
6. Bath. Such a building is usually attached to a wooden country house or cottage. In this case, one wall is common, and the other three are also built of wood. The most commonly used logs. The bath can be used as a vestibule at the entrance to the house.

For each type of extension, it is necessary to calculate the amount of materials and draw up a plan.

Types of construction of residential extensions

There are several basic options for do-it-yourself extensions to the house:

The first option is considered not only the easiest from a technical point of view, but also the most budgetary. He assumes that the roof of the main building remains in place, only slightly lengthening by the size of the extension to the house. The main building is completed on one side or two. Then a passage is punched between them so that the total area of ​​\u200b\u200bthe building increases by the size of the new building.

An attic-type room will be more expensive, as it is supposed to carry out an add-on.

The third do-it-yourself extension to the house involves its own roof. The rest of the structure resembles a side structure. A separate roof increases the consumption of material, so the extension will cost more and will be built a little longer.

The extension of the second floor is carried out only if the foundation of the house allows it. If initially the building was not planned to be multi-storey, then there may be problems with its completion. The foundation may simply not withstand the additional load. In some cases, it can be strengthened.

Designing a new building

According to the law, any functional room is considered to be an addition to the house. A balcony, a loggia, a winter garden or an additional bedroom – all this will be considered an extension. Mandatory elements of its design are:

• foundation;
• walls.

Unlike the main building, there may not be any ceilings here. Do-it-yourself constructive solutions for the roof of the extension are as follows:

1. Adjacency to the slopes of the roof of the house. In this case, new nodes are added to the existing truss scheme.
2. Gable connection is the most economical option.
3. Shared with the main building. The truss system of the house is dismantled from the edge adjacent to the extension, some elements are changed and everything is covered with a single piece of roofing material.
4. Detached structure – at

   An extension of the canopy is desirable when building a house

   increasing the number of storeys of the building, the roof is joined to the wall, relying on its own load-bearing structures.

The foundation of the building is recommended to be erected separately, since the structures are operated under different loads.
At the design stage, it is very important to take into account the compatibility of the new building with the old one. An extension with your own hands should not create obstacles to communications that pass through the site. If you plan to make multi-level buildings, then you need to consider that this will delay the snow masses. Therefore, they should be further strengthened to avoid subsidence of the foundation.

Foundation design

When increasing the useful area of ​​an existing building in the horizontal direction, it is unprofitable to build a slab or strip buried foundation. The most cost-effective foundation designs are:

1. Shallow-buried belt, which allows you to save the construction budget twice.
2. Pile foundation.
3. Do-it-yourself extension to the house on screw piles.
4. Pillar base suitable for non-foaming compact ground.

If preference is given to a pile or column foundation, then it is necessary to perform additional protection of the lower part of the structure from freezing. For this purpose, you can use basement siding with an inner layer of insulation in the form of basalt wool or expanded polystyrene.

Wall design

When drawing up an extension project, you should decide in advance on the material for the walls. For frame or panel construction, a sandwich is used:

• OSB sheets with EPS or stone wool core;
• inner vapor barrier membrane;
• outer foil for waterproofing.

The laying of lightweight blocks – aerated concrete or foam blocks – will cost a little more. If preference is given to the latter, then it should be taken into account that even walls made of the highest quality foam concrete are often covered with a network of cracks. Therefore, the facade will need to be plastered over the reinforcing mesh with a special composition.

Designing a roof

When designing an extension to a house with your own hands, you need to calculate the reliability of the elements of the truss system, their configuration and choose a step for their placement. If the height of the walls is the same, then the supports can be based on the existing load-bearing structures. The rafters of the lower extension to the two-story building should rest on the columns located near the walls of the main building.

Most often, the slope of the roof of the house closest to the extension is dismantled. The elements of the truss system are replaced by new ones that have a greater length.

Alternatively, the roofing pie can be dismantled, but the rafters cannot be dismantled. For a new building, a shed roof is being erected. You can strengthen the truss system with racks.

This is how the project of a house with an extension looks like

For an extension to the house with your own hands, it is recommended to choose a roofing material identical to that used for the main building. Then it will look the most harmonious.

Designing an extension to a private house

Most projects of individual houses provide only a residential part without additional outbuildings. Over time, residents, in the presence of free space near the house, often need to expand the structure with their own hands or with the involvement of qualified specialists. This can be due to a variety of reasons, such as an increase in the number of residents, the purchase of a car that will require a garage, and other circumstances. Annex – an auxiliary part of the building, which is adjacent to its main walls from one or more sides.

Varieties of attached buildings

Structure can be:

1. Open, in the form of a canopy adjoining the main wall, summer veranda, porch or terrace.
2. Closed:
   • living room with panoramic windows;
   • several additional living rooms;
   • kitchen with barbecue and dining area;
   • a separate recreation area, a children’s play complex or a sports gym;
   • insulated garage;
   • workshop with storage rooms;
   • sanitary facilities with a swimming pool or bath;
   • Russian bath or sauna, made mainly from wooden logs or timber as an extension to wooden houses;
   • greenhouses for year-round growing of vegetables, conservatories or winter gardens;
   • to accommodate boiler equipment for heating.
3. Attic superstructure, provided that the bearing capacity of the existing foundation allows such an increase in load.

Depending on the purpose, a heated warm extension or without heating is arranged.

Necessary approvals

A project for an extension to a private house can be ordered from specialized design organizations or developed independently. To change the design of the building, it is necessary to obtain a building permit from the local administrative authorities, which is necessary, as well as for the construction of the main house. The project should be coordinated with bodies a dignity. and fire supervision, communal department. If the distances from the border with neighboring plots, regulated by building codes, are not observed, a written agreement of the neighbors is necessary, preferably notarized. The illegality of the construction of an extension is also recognized in the absence of a written consent of all the co-owners of the building to carry out the work.

It should be borne in mind that a work permit is issued only with the existing registration of rights to own a land plot and a house in Rosreestr, taking into account in the state cadastre. In the absence of the necessary approvals, the structure may be declared illegal and subject to demolition. It is not necessary to obtain a permit for the construction of simple sheds or a porch.

Structures and materials for the construction of the superstructure of buildings

The added part must harmoniously fit into the overall interior of the house. A two-story extension to a one-story building will look ridiculous, which, moreover, will significantly complicate construction. It is recommended to use for the construction of walls the same materials from which the main structure is built. For an extension to a wooden house, use wood, and brick brick. You can use foam or aerated concrete blocks, and for a harmonious combination with the design of the house, veneer under a tree or brick. A high or turning porch, as well as open verandas and terraces, must be framed with a railing.

It is advisable to build the foundation of a capital extension to an old house of the same type as the one existing under the main building. Of course, for the construction of a simple canopy, porch or open veranda, there is no need for a powerful foundation. In most cases, a columnar foundation with a small laying depth or screw piles is sufficient.

Solid buildings and garages require reliable and durable foundation structures. Mainly prefabricated and monolithic tapes or a monolithic slab. When using poles and screw piles, it is mandatory to tie with a grillage, and to protect the space under the floor, pick up from the cladding with basement siding with insulation from basalt mineral wool or other similar heaters. On the top of the foundation, horizontal waterproofing is required from rolled waterproofing materials (stekloizol, hydroisol, rubemast or roofing material).

A good option is a frame extension to the house. The frame is constructed from wooden blocks filled with insulation (for example, mineral wool boards) and lined with thick moisture-resistant plywood, OSB boards or other materials. The attached building can be made with window openings. The doorway is more convenient internal, which allows passage to the attached part without going outside. But it is also possible to enter the device directly from the street.

The roof is most often arranged as a shed. It is important to ensure that snow does not accumulate at the junction, so the roof is made with a slope angle of ≥ 25 degrees. The canopy is most often covered with sheets of monolithic polycarbonate or ondulin.

The floor, depending on the purpose of the room, can be concrete (mainly in garages, workshops and storerooms), wood, lined with porcelain stoneware or tiles. Often arranged “warm floors”.

Garage walls are recommended to be built from non-combustible products (brick, concrete or lightweight concrete blocks) with reinforced concrete slabs or corrugated flooring. Be sure to provide a number of ventilation holes.

How to connect an extension to a house

The connection of an existing building with an extension is one of the most critical moments of construction. If construction technologies are not observed, cracks will inevitably form in the junctions with opening up to large cracks. This is caused by the difference in the existing loads and the complete absence or slowdown of the settlement of the foundation of the old house.

Attachment of the attached part is made in the following two versions:

1. With expansion joint without direct contact between foundations, walls and roof. It is recommended in the presence of problem soils (peat or clay). A gap is provided between the constructs, which is later filled with elastic heat and waterproofing materials. It is permissible to lay a board treated with several layers of bituminous mastic. The resulting seam is closed with decorative inserts. Be sure to eliminate the possibility of the formation of “snow bags” on the roof at the interface.
2. Inclusion of all constructs in joint work. The new foundation is arranged with occurrence at the same depth as the existing one. It is applied at the bases from the soils which are not subject to heaving. The contacting surface of the old one is cleaned of soil, a layer of waterproofing, and a notch is made with a perforator. Reinforcing bars are tightly hammered into the drilled holes with sealing of the holes. The obtained mortgages are connected by welding with the reinforcing cage of the extension foundation, and concreting is carried out with a thorough compaction of the mixture using a deep vibrator. Brick walls are connected in the same way. The rods are placed every two rows in the seams of the new masonry. Wooden structures are tightened with steel bolts or studs with double-sided thread, complete with wide washers, nuts and locknuts. To pair the roof, it will be necessary to remove part of the roofing and jointly fasten the rafters and beams of the house and the extension with the addition of new additional nodes and racks. In some cases, it may be necessary to build a common truss system or replace elements of greater length.

The second option is more complex, laborious and costly, although it cannot be guaranteed that the joint of the joints will not disperse over time.

Depending on the design, materials of the existing house and the purpose of the attached premises, the foundation type, material and wall thickness, truss system and roofing materials for the new building are selected.

Before making a decision on how to build an extension, it is necessary to foresee all the possible nuances of future construction and ensure that you protect yourself from possible administrative sanctions.

Advantages of an extension compared to a detached building

• Reduction in the volume of work on the supply of engineering communications (electricity, water supply, heating, sewerage, ventilation).
• Less material consumption and cost of construction, since at least one existing wall is used.
• Rational use of the territory without cluttering with additional buildings.
• Additional insulation that prevents the penetration of cold air directly into the house with a reduction in heat loss.

• wall kit

Extension to a wooden house: projects

Quite often it happens that the construction of a private house was carried out without the construction of outbuildings, but then the need for them arose. Modern house designs often assume only the utilitarian function of the house – people will live there. But what, that a person will also conduct some kind of economic activity – no. In addition, sometimes there is an urgent need to increase the living space of the house. An extension of foam blocks, a brick extension, a wooden one – the creation of these structures will help solve this issue once and for all.

Types of extensions

The type of buildings is determined depending on what exactly should be in it. It can be a room, a toilet, a garage, a kitchen, and anything. By the way, in central Russia you can often find a building in the form of a greenhouse in which you can grow fruits and vegetables even in winter.

Scheme of the device of the garage-extension

Indeed, in this case, all the necessary engineering communications can be easily extended from the house. Of course, the construction of the structure must be agreed upon, even if we are talking about wooden terraces or simply attaching a veranda to the house.

Creating a project and choosing the location of an extension

Projects and construction of such structures involve the following steps: .

Arrangement of a frame house in a section

For example, if it is necessary to attach terraces to a wooden house, then it is better to let it be wooden. Of course, this rule is not always possible to comply with.

Let’s say a person wants to breed chickens, he needs a high-quality, windproof, warm outbuilding made of bricks. In this case, this option should be preferred, despite the fact that the house is wooden.

Options for the location of extensions to a standard wooden house

Calculation of estimates

Actually, the estimate itself is not so difficult to make, it must take into account the following:

An example of a veranda attached to a wooden house just wooden household blocks. This will help you avoid unpleasant surprises in the future.

Construction of the foundation and connection of the foundation

In Russia, bathhouses are often attached to wooden houses

Even the construction of an ordinary terrace for a wooden house involves the creation of a new foundation for it. The option of extending the old foundation disappears immediately: it is impossible to do this, but to combine both foundations into a single whole later is not only possible, but also necessary.

For example, even under wooden terraces you will need to make exactly the same foundation as the main house. So, first you need to decide on the type of foundation itself.

General scheme of the device of the pediment of the frame house

Actually, there are 3 foundation options that can be used as a base for an extension:

1. Monolithic;
2. Columnar;
3. Tape.

The column foundation is used extremely rarely in Russia, since it can only be installed on very hard soils such as mountainous ones.

It can be used, for example, to build a gazebo, however, such structures are usually not attached to the house, but placed next to it. By the way, instead of a foundation, you can take old tires for a gazebo – this will be quite enough.

Scheme of laying an extension from foam blocks

A monolithic foundation will be the most durable, however, its installation is not always advisable.

Monolithic – the most solid foundation, as they say, “for centuries.” However, the cost of its construction, as you might guess, will result in a tidy sum, and the labor costs will be very, very impressive. In general, it is better to choose a classic strip foundation, which is ideal for any extension to a wooden house.

Placement of communications

An example of a garage extension to a wooden house

As noted above, placing any communications in an extension is as easy as shelling pears, because the room will adjoin directly to the house itself. What does it say?

For example, it is enough just to extend the existing water supply, sewerage or heating system – that’s all, no pits and exhausting welding work. The same applies to the laying of electrical wiring, which, probably, even the most negligent worker can carry out with the help of a puncher.

Another thing is when it comes to really complex engineering systems. Let’s say you need to draw a branch from the main gas pipeline into the annex. First, no one will do it on their own.

Installation of a veranda attached to the house

Secondly, it will require, speaking without exaggeration, colossal monetary expenses. So, here’s something to think about. For example, in the Kuban you can often find kitchen extensions to wooden houses.

And even if there is gas in the house itself, then in the annex there will still be a gas cylinder or the same electric stove (a stove is also a common option). Such nuances must be taken into account.

Communication with other premises

The question of how to make an extension to the house, even if we are talking about such a type of work as an extension of a veranda or another extension from a bar, should also involve solving the problem of communication between the attached structure and the rest of the house .

There are 2 solutions to this problem:

A covered terrace is a great extension

1. An extension to a house made of timber can be connected to the house using a doorway made in the main wall of the house;
2. Entrance can be from the side of the street (an extension to the house made of timber makes it easy to implement both options, but another material made of wood does not).

In the first case, the solution will be convenient, because, in fact, the living area of ​​the whole house is increased. But there is one extremely important nuance: the approval process in this case can take many months, because it is necessary to make changes to many documents.

Yes, and the load-bearing wall of the house can be seriously damaged. If the owner of the house is ready for such a development of events, then, of course, it is better for him to prefer this particular option, and not any other.

Be very careful when cutting an opening in a load-bearing wall!

If there is not enough money and there is no desire to go through the bureaucratic circles of hell, then the option with the entrance from the courtyard will not be so bad. Moreover, in terms of cost, it will come out much cheaper.

An extension to a wooden house is considered an excellent option for expanding the area. Projects offered by experienced craftsmen will help you choose the right option, as well as prepare all the required materials in advance. Additional space may be needed to create a veranda, summer kitchen, boiler room or terrace. It is easy to make such a room with your own hands, but first you need to choose the type of extension.

Extension to a wooden house. Structural designs in various materials

Depending on the material used in the construction, the following types of outbuildings can be noted:

• from timber;
• frame;
• brick;
• from foam blocks.

Small glass extension

Frame extension

Frame structures are installed in the shortest possible time. The installation process is quite easy, so when creating an extension to the house from the frame, you can do it yourself. In terms of quality and thermal insulation characteristics, frame construction is in no way inferior to more solid and bulky structures made of brick or foam concrete. The use of this type of construction is especially relevant if the construction of a two-story extension is planned, since it has a much lower weight.

Frame construction – the fastest installation time

Good advice! A frame extension to a wooden house needs a foundation. Suitable ordinary tape, covered with waterproofing materials.

Construction of a frame extension

Stages of work

For a wooden frame, you will need a 15×15 cm beam and boards – 15×2.5 cm. If a metal frame is needed, then pipes, channels or corners are used for this. At the beginning of work, a strapping is laid around the perimeter of the foundation. Then, using the level, corner support pillars are installed, and after that – intermediate racks.

At the height of the planned ceiling, a trim of boards or smaller pipes is also made, after which the floor beams are laid and fastened to the upper trim. The fastening of a wooden structure is carried out using a drill and wood screws, metal – by welding.

Outbuilding with large windows

All materials are suitable for sheathing an extension to a framed house. It can be boards, plywood or others, depending on the budget allocated for the extension. Once the frame is fully assembled, it is insulated using any heat-insulating materials.

The following are commonly used for this purpose:

• mineral wool;
• expanded polystyrene;
• basalt mats;
• foam.

In the extension to the house, you can equip a living room with a kitchen

In advance, an approximate scheme of a future extension to a wooden house can be attached to the project documentation. Projects of any structure with schematic images will greatly facilitate the task of the master.

An extension can double the living space

An extension to a house made of foam blocks or bricks

The technologies for building an extension to a house made of foam blocks and bricks are almost the same. Foam concrete blocks are the most common material. Due to the lower cost and ease of work, it is used much more often to create both capital houses and extensions.

Green roof extension

Good advice! If it is planned to organize a bathroom in the annex, then foam blocks should not be used to create it. They absorb excess moisture too well, which often leads to their destruction, especially in the absence of proper ventilation.

The use of stone and wood in the arrangement of the extension

The extension of foam blocks also provides for the preliminary arrangement of the foundation. It can be monolithic or tape. It is also necessary to decide in advance on the method of attaching such an extension to a wooden house. The project usually provides for all sorts of subtleties that affect the shrinkage of buildings made of various materials.

Specialists will perform the correct calculation depending on the quality of the soil, the level of groundwater, as well as the shape of the extension, and will conclude that it is necessary to attach one building to another.

A kitchen is equipped in the annex to the house

Approximately one month after the foundation has been laid, the laying of foam blocks can begin. Do not forget about laying a layer of waterproofing, it will protect the walls from excessive moisture. Construction starts from one corner. Subsequently, it will be a kind of guideline for leveling the walls. After raising 2 rows on the masonry, it is worth laying out the reinforcement bars. This is necessary for a more durable and high-quality adhesion of the walls of the future structure.

Scheme of arrangement of an extension to the house

The last stage is the arrangement of the roof. It can be made separately for an extension to the house from foam blocks, or you can remove the roofing material from the main building and make a single roof. When creating a roof, it is necessary to provide for the correct angle of its inclination in order to carry out a full drainage of precipitation.

Extension to a wooden house from timber

The option of creating an extension from timber depends on what kind of premises will be located in it: residential or non-residential. A separate foundation, a connecting wall, is created for the living room. The space between it and the main building is filled with mounting foam – the so-called expansion joint is being equipped. This is necessary so that when the new structure shrinks, the walls of the house are not damaged.

Timber extension

Good advice! The depth of the monolithic foundation of the extension must be the same as that of the main structure. The foundations need to be interconnected. For these purposes, reinforcement is used.

Wooden extension to the house

It is possible to provide a pile foundation for an extension to a wooden house. The project must include the calculation of this structure. The foundation on piles is much more economical than its monolithic counterpart and greatly facilitates the finished structure.

Small wooden extension

The walls are made of profiled timber in the same way as in the construction of a residential building. For walls, a beam of 15×15 cm is used, and for the floor and partitions inside the extension, a thinner material with a section of 10×15 cm is suitable. After laying the first row, the wood is treated with an antiseptic and logs are already laid on it. The gaps between them are filled with heat-insulating material to avoid drafts in the future, and after that the main floor is mounted.

Open annex – terrace

When building walls, each row is fastened together using dowels (wooden pins). This vertical connection provides strength to the structure, preventing the beam from moving. Corner joints are made in a special way called “warm corner”. To do this, a groove is cut in one of the connected bars, and a protrusion of approximately the same size is made on the other. Particular attention should be paid to the creation of window and door openings.

Project for the construction of an extension

A few tips for building extensions

Before starting construction, it is worth considering some of the subtleties of building an extension to a wooden house. The project usually provides for many nuances, but when creating it, you need to know that the length of the extension must match the length of the wall of the main house. The width of the additional room can be any. The best option is 3-3.5 m.

Living room with a seating area in Annex

When choosing a place for an extension, you should not tie it to the front door. It is quite convenient when the access to the terrace or summer kitchen is made from the living room. When creating a bathroom, an extension is built with an exit from the corridor or from the bedroom. A doorway in the wall of the main house is best equipped in place of a window, since there is already a supporting structure there that relieves the wall from ceiling pressure.

Veranda extension

By following the basic rules for building extensions and taking into account some nuances, you can create a really reliable structure that will last for a long time. It is easy to do it yourself, you just need to carefully consider each of the stages of work and do everything in accordance with the prepared project.

projects, examples and options, building technology

There are a number of reasons why you have to make an extension to a wooden house. Usually this is caused by the need to expand the usable space, provide an additional vestibule in front of the entrance to the house, or the desire to make a whole terrace or a spacious veranda. In any case, the extension to the house should not become a dark spot that will block the entire view. It should become a useful and attractive highlight, as in the photo.

Preparing for the project

Before starting construction, you need to decide on the project, appearance, decor, materials, because it is not necessary that an extension to a wooden house should be made of wood, and also determine the requirements for the foundation. And only then can preparations for construction begin.

not only the appearance of the extension, but also its functional features will depend on the quality of the project.

How to properly prepare for such a large-scale project? First, you need to calculate the time of construction work and prepare all the necessary raw materials. Secondly, you will need special tools, the choice of which largely depends on the type of construction and materials, for the processing of which you will also have to select the necessary tool. Thirdly, you should separately prepare for attaching and decorating a new building with decorative elements, because sometimes decorating can take even longer than the construction itself.
Projects for extensions to a wooden house can be taken ready-made and adapted to the conditions, or, more logically, create your own plan. For beginners and inexperienced builders, the first option is still the best option, but your own plan, design and structure of the building will always satisfy the taste of the owners of the house by an order of magnitude. In any case, it is worth considering the simplest, but key points of the extension, and after that decide whether it really needs to be done or not.

Outbuildings

A wooden extension to a wooden house and any other will be much more profitable than, for example, a stone one, because wood is easier to process. Moreover, the presence of very heterogeneous materials in one building (for example, stone and wood) causes dissonance and more often can only damage the aesthetic appearance of housing.
Wooden extensions can be built in three basic variations:

• on a foundation separate from the house, but with a common roof;
• with separate foundation and ceiling;
• attic, bay window and other outbuildings on floors, except for the first one.

An attic attached to an old house on the roof or on the second floor can change the look of the building quite a lot. The complexity of such a construction is that it creates additional loads on the foundation, and this is fraught with its shrinkage. Therefore, the third option is not the most reliable, although profitable, since there is already a starting foundation for the extension.

Choose an extension in such a way that it blends in harmoniously with the overall appearance of the building.

A separate foundation is also a risk. Preparing the foundation for an extension can disrupt the structure of the house itself, so this process is always carried out with extreme caution. A well-made foundation almost half ensures the success of the building.
Choosing the type of coverage is always a difficult topic. Additional supports on the roof of the house increase the pressure on its structure, although they bind both structures well. And in the case of individual roofs, leaks or even crevices can occur between the extension and the house, if suddenly the foundation begins to sag at least under one of the buildings.
Thus, it is better to consider an example of a wooden frame-type building with a separate roof.

Foundation

Experts suggest making the foundation of the attached structures the same as that of the main building. That is, if concrete or foam blocks are used, before construction, it is necessary to study the soil in detail, the possibility of creating an additional foundation, and also take into account the risk of shrinkage. If there is no risk of shrinkage, then the common roof will connect the two structures well, otherwise, the connection of the two buildings should have some mobility and elasticity, not be rigid.

Before pouring the foundation, carefully study the soil.

If another extension was made earlier or to a wooden house, projects of potential additional buildings are attached, then these drawings, which have been preserved, can be used as more or less reliable and reliable. Although it is still worth doing your own soil test.

If shrinkage is not terrible, the ground is solid, and the preparation of the foundation of the new structure will not harm the main building, then you can safely fill or dig in to install blocks or other foundations.

In the case of wooden or reinforced concrete piles, as a rule, such problems do not arise, but before installation, you still need to make sure that they are reliable, durable, and also treated with impregnations and antiseptics. After installing the foundation, you can begin to mount the frame of the future veranda or terrace.

Frame

Frame construction is the second most important aspect after foundation preparation. The entire extension to the house, and especially the roof, will transfer all its weight to the frame. The slightest curvature or mismatch in height can significantly reduce the life of the structure.

Timber framing requires wood beams with good load-bearing capacity. If a veranda is being made, then it is necessary to take into account the need to form walls and additional vertical lintels in them, and for a terrace it is worth considering the possibility of the complete absence of such walls.

Other construction options can use metal profiles and supports or even masonry, but this will of course require a stronger foundation than conventional wooden beams.
The frame is built taking into account the total weight of the structure, as well as additional loads – wind, precipitation, possible snow on the roof in winter. For terraces, it is best to make a lightweight version of the design, or to foresee the possibility of covering open parts with a tarpaulin or light wooden shields.

When designing the framework, consider the total weight of the structure as well as the climatic conditions of the area.

With a separate roof, its frame should be made single-pitched with a slope towards the street, not the house. In this case, single-sided wooden trusses manifest themselves in the best way as part of the frame.
Roof options and semi-circular orientation available. Although it requires additional skill, skills, time to prepare and implement the project, this roof option still provides a lot of advantages. For example, a roof with a semicircular slope can have a chimney hole at the top, which allows you to install a brazier right in the middle of the terrace even in winter or in the rain.

Walls and insulation

Walls in a wooden extension, if it is a veranda, that is, a closed room, are made taking into account the location of the door, windows and the need for their insulation.
Ordinary boards are rarely used to finish the walls of the veranda inside and out, but for terraces, the use of a special terrace board is the way to go. Terrace board or the so-called decking, especially from composites, can withstand any level of moisture, therefore they are used in open-type extensions.
It is easier and cheaper to decorate a veranda with chipboard or OSB boards. They are usually placed in two layers – on the outside of the racks and inside. This is due to the requirements for insulation.

When choosing wall material and insulation, consider the level of humidity.

There are many ways to keep an extension warm, but the most popular way is to use insulation between the studs of the frame. Mineral wool or other insulation fixed between two chipboard plates will perfectly retain heat in the room. For better insulation, additional materials should be used – seam tapes, mastics, and so on.
Doors and windows can be made of plastic or made of wood. In the case of a terrace, they are basically not needed.

It is important to properly design the roof, which usually uses a metal profile or a temporary cover in the form of tarpaulin if the building is intended for only one season.

Almost any decor of a veranda or terrace is possible – from ordinary painting to covering with siding or clapboard. Decorating is a matter of taste.
In this way, a simple and fairly cheap do-it-yourself construction is obtained, a place of rest or just a working extension. Having chosen the right dimensions, having prepared the foundation, materials and having thought through the proper design, everyone can make such an extension to the house of wood. The main thing is to decide on it.
