When adding extra space to your home, you not only have to consider how the new space will affect the flow of your interiors, but also how the extension will work with your home’s existing exterior. Your choice of roof design is an important element in how the addition will work with the original building.

Whether you want something sympathetic or to create an eye-catching contrast, you have various options when it comes to designing the roof for the extra space you are creating.

Here are some great examples to spark some inspiration.

1. Duo Pitch Roof on Contemporary Extension

Homeowners Charlie and Rose Thomas worked with architectural designer Charlie Luxton to design the contemporary extension that replaced an aging conservatory. While the extension features a modern steel structure and a large amount of glazing, the roof features stone slates to provide a sympathetic nod to the original cottage.

The pitch of the extension’s roof complements the original building, creating a sense of harmony between the two elements.

2. Flat Roof Extensions to Victorian Home

Nils and Lisa Feldmann added two contemporary-style extensions to their Victorian villa in Leicester. Both extensions feature flat, green sedum roofs that offer a striking contrast to the pitched roof of the original property.

3. Catslide Roof on Sympathetic Extension

Homeowner Helen was keen that the extension to her 16th century cottage should mirror the older sections of the house. By choosing a catslide design (where one roof slope extends down further than the other) covered in similar roof tiles to the existing roof, as well as complementary brickwork, the new extension fits seamlessly with the original cottage.

4. Monopitch Roof on Modern Cantilevered Extension

Paul and Elaine Haffey chose a monopitch roof for their contemporary cantilevered extension. The monopitch design allows for the homeowners to make the most of the rural views, as well as adding an interesting twist to the whole project.

This radical remodel and extension project has transformed a dated bungalow. The project features a twin gabled roof design to help create the space needed for the new storey, creating great architectural wow-factor when combined with full-height glazing, white render, timber cladding and slate-effect cast concrete tiles.

7. Unique Twisted Roof on Extension to Grade II-listed Cottage

In order to create the required head height for the staircase but also keep the existing window, a unique twisted roof was the answer.

While it looks like an impressive architectural gesture, it is also an effective and practical solution to the problem.

The homeowners of this traditional-style house chose to go for gold when they decided to transform their detached home by extending both down and out, introducing a flamboyant, sculptural wing-like roof clad in a gold-coloured copper alloy that would not look out of place in a modern art gallery.

5 Of The Best Roof Design Types For Home Extensions

Love your home? Can you really call it your ‘dream home’ yet? To get the perfect space for your family, your investment and your lifestyle, the perfect addition is a beautiful verandah, carport or other extensions. Drive-up your re-sale value, add liveable floor space and enhance your options for entertaining with a custom designed structure that can be used every day of every year.

With Mr Verandah, we take care of the entire process for you – from design to planning and building. So, let us ask you this question today: What type of roof design is perfect for you? Follow our guide to some of the most exciting and popular extension roof designs that might help you make your important choice.

1. Gable Roof Design

Remember Anne of Green Gables? Remember the beautiful pitched roof design – in green? Well, a gabled roof is still extremely popular today, not just because designers and builders are so used to them, but because these types of roofs work for every climate – especially rainy and snowy ones! Easily recognisable from its triangular shape, a gabled roof is often called a pitched roof or peaked roof. As well as looking truly classic, a gable house roof design for your home extension is very low maintenance with minimal wear and tear.

2. Flat (Skillion) Roof Design

Thinking ‘flat’ – especially for your verandah or carport? Think skillion roof, instead. It’s basically a standard flat roof design with a simple and sleek single flat surface that is notably steeper, with a more noticeable pitch than the flat roofs you are used to. This stylish and minimalist flat roof design is gaining steam in Australia, as the drainage problems tend to be non-existent, and they’re also more affordable to build.

3. Curved Roof Design

How about something completely different? Also gaining incredible popularity in Australia are chic, modern and trendy curved roofs, which will really make your verandah design stand out from the crowd. In combination with other flat or gabled elements of your home, it’s a sophisticated option that adds soft organic curves and is not inferior in any way in terms of drainage.

4. Hip Roof Design

This option really is hip – and we don’t just mean trendy. Types of roof in the hip design category differ fundamentally to gable roofs in that all four sides slope downwards (think of a pyramid). To the untrained eye, the final product looks a lot like a gable solution, but they’re brilliant in handling storms and high winds.

5. Dutch Gable Roof

If you really do have your heart set on a traditional gable roof, let us at least introduce you to its big brother – the Dutch gable design. Basically, it’s a hip-plus-gable combo package, with the gable portion constructed atop the hip base. The style dates all the way back to the Renaissance, so it’s no surprise that it looks great with its notably high pitch and it works well with any material.

 

Want even more options? Have you heard of the horizon, bullnose, bonnet, clerestory, parapet – and others? Got something truly special in mind or really hanker after something out of the ordinary? At Mr Verandah, we’re always full of ideas and we can help bring some of yours to life too, in order to make your verandah, carport or extension something to love forever. Your dream home really is just a step away, so get in touch with our Melbourne extension builders today.

Frame extension to the house: step by step instructions and recommendations | Informational articles from the company Yuzhny Dom | rostdomik.ru

Over time, residents of a private house are faced with the need to increase the living space of the building. The most economical and technologically simple solution to this problem are frame extensions. Structures of this type allow the use of various types of foundations and can be combined with both wooden houses and buildings made of brick or foam blocks.

Interfacing with the main building

Regardless of the specifics of the design and the state of the foundation of the house, the difference in pressure that the extension and the existing building create on the ground can lead to their mutual displacement. Due to this feature, architects categorically do not recommend rigidly connecting two bases to each other. During construction, it is more expedient to use a movable contact zone, for the organization of which two beams are mounted on the wall of the main building, between which a third one is inserted, which is an element of the extension itself. This version of the tongue-and-groove connection makes it possible to level the mutual displacement of the two structures.

A similar problem arises when installing the roof of an extension. In this case, the rafters at one end are joined to the upper trim of the frame, and at the other end they are connected to the existing rafters of the main house. At the same time, the crate is superimposed in such a way that the rafter junction area is located between the details of the crate. As a roofing, materials with a certain margin of flexibility are used – soft tiles, corrugated board with a small wave height or similar.

Foundation installation

The situation when, during the construction of an extension, it turns out to use the foundation laid for the main house, is a rare exception. Most often, for new structures, a new foundation has to be erected. Ideally, builders recommend forming a new foundation, identical to the existing one in configuration and depth. This approach minimizes possible subsequent deformations of the two parts of the dwelling. However, in some cases it is not possible to ensure full compliance. In such situations, it is mandatory to use the so-called. an expansion joint, which, in combination with a movable joint, will make it possible to compensate for possible displacements of the two structures.

Installing the tie bar

After preparing a new foundation, a strapping is laid along its perimeter, the recommended width of which for the domestic climate is 150 mm or more. This size is associated with the need for subsequent installation of a multiple-width insulation. When erecting a deliberately non-residential extension, it is allowed to reduce the dimensions of the timber to 100 mm.

Frame assembly

The most important part of this stage is the installation of vertical racks. They are recommended to be installed in increments of 60 cm, which corresponds to the width of typical mineral insulation boards. This approach makes it possible to simplify subsequent work and use building materials with a minimum of scraps.

Installation begins with the installation of corner posts, the dimensions of which are also recommended to be selected from 150 mm or more. This makes it possible to pre-determine the safety margin of the entire structure. When installing corner elements, it is strictly necessary to constantly check the building level. After assembling the first racks, the rest are built up between them, taking into account the width of the panels of heat-insulating material.

Top rail assembly

The installation of the upper trim is carried out similarly to the installation of the lower one. At the same time, it is permissible to extend the beams beyond the crown to a distance of up to 30 cm. Upon completion of the assembly, a crate is sewn onto the upper crown, which will play the role of a supporting frame for the roof. On top of it, in turn, any rolled insulating material (roofing felt, parchment, etc.) is laid, which provides additional insulation of the room in case of a roof leak.

Rafter system assembly

In the event that the construction of an extension does not involve re-laying the entire roof, the organization of a shed roof becomes the most economical and technologically simple solution. This configuration is compatible with almost any existing roof, including the most complex designs with broken shapes. Rafters on one side are installed under the slope of an existing roof, and on the other side they are laid on the top trim of the extension. For additional rigidity, they are fixed with metal corners.

The most important task at this stage is to maintain the angle of inclination of the rafters. If it is violated, the slope will begin to bend in the horizontal plane, which will lead to an uneven load on the bearing parts.

Roof sheathing

When distributing roofing material along the crate, it is necessary to ensure that at the top of the slope it goes under the sheets of an existing roof. To ensure this, it may be necessary to temporarily remove the bottom row of cladding and fasteners on the house.

When choosing a roofing material for an extension, it is recommended to proceed similarly to the design of the foundation and dwell on the material that is as close as possible to that which the house is already covered with, while remembering the need for a flexible connection at the junction of the main structure and the object under construction.

Wall and floor insulation

Upon completion of work on the roof, the installation of floors in the extension begins. At the preparatory stage, a rough floor is laid, the material for which is usually used semi-edged boards. Insulation plates are laid out on the resulting plane and lined with a rolled insulating coating. After that, the surface is leveled and a finishing coating is mounted on it. Walls and roofs are insulated according to similar schemes. After the outer cladding layer, a rolled wind protection is laid out, after which the space between the vertical posts is filled in layers with sheet insulation. In this case, an important factor is the displacement of subsequent rows of plates relative to the previous layer. This configuration avoids cold bridges formed at the joints.

Upon completion of the installation, the insulation from the inside of the wall is tightened with a rolled vapor barrier, after which the base is sewn for a fine finish (drywall, OSB or other similar materials).

Insulation plates are sewn onto the crate of the ceiling using self-tapping screws, after which they are also covered with a finishing material.

An important factor determining the success of frame construction is the mandatory drying of all lumber, as well as fire and bioprotection treatment. In addition, it is necessary to carry out calculations in advance of all sizes (window openings, door groups, etc.) and constantly check with building level indicators during installation. Compliance with these requirements will not only greatly facilitate the work on the extension, but also provide confidence in its reliability.

Metal framed outbuilding

A metal framed house extension is a strong and durable foundation for your building.
It happens that there is a need to attach an additional building or room to the house.
It is possible to attach a garage, a utility block, a veranda, a terrace, a dwelling, a balcony to the house.
All of these structures are called extensions because they adjoin directly to the main building.
It is easier, faster and cheaper to build extensions to the house on the basis of a metal frame.
An extension on a metal frame is durable, cheap, easy and fast to erect.
Our company MATALLVARIM.RU has been manufacturing and erecting outbuildings on a metal frame for many years.
We have accumulated vast experience in the construction of metal framed outbuildings and can help you with the implementation of your ideas.
An extension on a metal frame to the house turns out to be light, strong, inexpensive and durable.
The speed of manufacturing an extension on a metal frame, ease of installation, independence from access roads make this method of building an extension optimal.
Also an important factor is the flexibility and ease of configuring the extension frame. Metal is the perfect material for this.
The foundation for the metal frame of an extension to the house can be piles, a lightweight concrete slab, a block or shallow strip foundation.
The foundation for a metal-framed house extension must be such that the metal-framed house extension is in the same ground conditions as the main building or house.
For example, if the house is on blocks, then the extension must be placed on blocks.
If the house is motionless, that is, it stands on a reliable foundation that does not move when the soil freezes seasonally, then the foundation of the extension on a metal frame must be appropriate.

Benefits of a metal-framed house extension:

– Price
– Speed ​​of erection
– Ease of erection and configuration
– Durability
– Durability
– Ideal and unchanging geometry
– The metal frame of the extension is simple and flexible in configuration.
– The metal frame of the building is easy and convenient to sheathe and insulate.

Materials and construction of an extension on a metal frame to the house.

– As a rule, an extension on a metal frame to a house is made of a square pipe 60x60mm, 80x80mm, 100x100mm and a rectangular pipe 60x40mm, 80x40mm, 100x50mm
– The frame of an extension on a metal frame to the house consists of racks, strapping racks, openings for windows and doors, floor joists and roof lathing.
– Sheathing an extension on a metal frame is not difficult.
The sheathing material is fastened with self-tapping screws either directly to the profile pipes of the frame, or to lugs, plates and fasteners specially welded to the frame.
Wood, siding, sandwich panels, corrugated board and other types of materials are most often used as sheathing for an extension on a metal frame.
Very often, the sheathing of an extension on a metal frame is made of double-glazed windows or monolithic or cellular polycarbonate.
It is possible to attach a wooden crate or logs to the metal racks of the extension frame on a metal frame and to make a sheathing on them.
It is just as easy to insulate an extension on a metal frame – the insulation is laid between the inner and outer skin of the extension frame.
– The foundation of the extension on a metal frame is the most important element of the entire structure. It is desirable to make an extension on a common foundation, or on a similar and homogeneous foundation, in order to avoid deformations and distortions due to seasonal fluctuations in the ground level when the soil freezes.
It is better not to tie the extension frame rigidly to the house.
We most often use piles of black or galvanized pipe as the foundation for the extension frame.
Also, an extension on a metal frame can be erected on a block foundation, shallow strip foundation or on a lightweight concrete slab.

We can make for you an extension on a metal frame of any shape, any configuration, taking into account all your wishes and in the shortest possible time.
