The desire to increase your country house Over time, it appears in almost every owner of a private home. And an excellent solution in this matter would be an extension to an existing house.
Begin construction work from drawing up a project, where it is worth drawing a clear plan of the planned object, thinking through the connection of all premises with existing house, choose the type of structure, foundation and decide which building materials will be used. The correct development of the project stage will determine financial expenses during construction. At this stage, it is also worth deciding on the nature of the use of this building, namely, whether it will be seasonal or year-round, and also decide how many storeys the new building will have.
There are several common types of extensions that can be classified according to their purpose.
Summer room (kitchen or veranda).
Such an extension is usually one-story and is used in the warm season. It is convenient for spending time together, family dinners, relaxation, etc. Of course, a lung or shallow foundation, preferably independent from the main building of the house.
Such a structure usually has pitched roof(Fig. 1, 2). It is recommended to use metal tiles or polycarbonate as roofing materials. In this case, it makes no sense to do thermal insulation, because the room will not be used in winter. It is worth noting that minimum angle the roof slope is 8°, you cannot do less, otherwise leaks will appear after rain and snowfalls.
Living room and attic, if the extension is two-story (Fig. 3, 4).
In this case, a more thorough approach will be required for constructing the foundation, erecting permanent walls and roofs, as well as installing waterproofing and thermal insulation materials, supply of all utilities.
Should be given special attention thermal insulation of walls, roof and floor, taking into account that the extension will be used in the cold season, and accordingly heating.
Before starting construction, you need to consider the condition of the house. The pairing of roofing and foundation structures will depend on this criterion. And it is worth considering that due to the difference in the magnitude of the load that the main structure and the extension will exert on the ground, there is a high probability that over time they will move relative to each other.
Another option for an extension to the house could be a separate building, closely adjacent to the main one., which quite often becomes the only possible
due to the fact that old house may not withstand the reconstruction of the roof, and this will compromise the stability of the entire structure.
Also the extension may differ in the type of foundation. Usually, a separate foundation is arranged for an extension, which is connected to the base of the old house using embedded reinforcement.
Of course more correct option- This is the general foundation that is laid at the stage of building a house. However, this happens quite rarely, and therefore it is worth ensuring maximum similarity of the foundations in terms of material and depth.
The most constructive and competent solution may be a separate foundation for the extension. The most common in this regard today is the foundation on screw piles(Fig. 5, 6). After screwing into the ground, the piles are combined into a single grillage by welding several metal channels or wooden beams. This results in a separate and independent foundation that will not be connected in any way to the main house, since the existing foundation can continue to move downwards, which can lead to deformation of the structure.
At the same time, between two buildings a minimum of possible distance, i.e. a technological gap that is filled with thermal insulation and waterproofing materials.
The extension to the house can be made using frame technology or from wooden beams (Fig. 5, 6).
Frame technology the most acceptable, since it is light in weight and consists of the construction of a frame made of wooden beams and filled with insulation. For example, these can be SIP panels, which in cross-section represent a three-layer “pie” of two load-bearing surfaces (usually OSB), between which foamed polystyrene foam is pressed, where the thickness of the insulation can be different, so you can select panels for any climatic region. In this case, no cladding is required additional materials, which will reduce construction costs.
It will be enough interior painting panels varnished. It is also worth saying that timber extension to wooden house can be of two types: three walls and a fourth load-bearing, which is already in the house, or three walls, which is the most reasonable in terms of material consumption. If planned winter accommodation, then it is worth using a material whose cross-section is at least 150 x 150 or 200 x 200 mm.
This beam is quite heavy, but it will also last longer. After the walls are erected, the remaining cracks must be sealed, otherwise it will be very cold in the extension. You can do this using modern insulation materials based on basalt wool or polyurethane foam.
The desire to improve your living conditions by increasing the number square meters appeared to every owner of a private house. Apartment owners are not lagging behind in this and would also be happy to add at least one room for themselves.
There is nothing impossible about this, extensions to apartment buildings are a dime a dozen, you just need to know how to do it correctly, and not only from a legal point of view. The key to successful construction and comfortable stay – proper organization works and compliance with process technology.
Extension layout
The construction of the extension begins with, perhaps, the most important thing - with permission for this very construction. Without the appropriate piece of paper, you can run into a serious fine, and the money spent will be wasted.
The next stage is also theoretical. Determine what purpose the extension being built will have. Will it be a living space or a winter garden, a storage room or just an emergency exit porch. Cash injections into construction directly depend on the purpose of the structure.
Logically, it would be correct to draw up a drawing; the drawing helps to understand how to make an extension to the house, make approximate calculations for the quantity required material. Then they go to the site of future construction and transfer the drawing to the site, indicating the dimensions of the extension using a cord and metal or wooden pegs. It is on the spot that they carefully examine how the new foundation will be combined with the existing one and whether the future extension fits into the architecture.
Material selection
The material of the extension and the house are usually the sameExperts advise approaching this issue simply: from what material the main house is built, the same should be used for the extension. Simply put, if the house is wooden, then a wooden extension should be added to it. The same applies to brick and concrete. But technical progress in the field of building materials does not stand still, and now universal materials have appeared, such as foam and gas blocks. In addition to its versatility, it is an environmentally friendly and heat-saving material. You can veneer such an extension decorative slabs, imitating the material of the walls of the main building, which will create the appearance of execution in a single style.
But there are also exceptions. In some climatic zones, it is possible to make a wooden extension to a concrete building if it is used as a storage room or garage. You can even build a bathhouse from logs and attach it to your apartment. Flights of fancy in such cases are limited only by financial possibilities.
Construction of the foundation
Most important stage construction – . Even the strongest walls made from modern and expensive materials will be useless on a poor and flimsy foundation, so the answer to the question of how to properly build an extension to a house is to choose the right foundation. There are three main types of foundation:
- monolithic made of reinforced concrete, ;
- columnar.
![](https://i1.wp.com/small-house.ru/wp-content/uploads/2016/01/kak-sdelat-pristroyku-k-domu-sovetyi-e-ksperta-03-220x162.jpg)
The first option is universal, it is suitable for all types of buildings, the same applies to a columnar foundation. The pile version is suitable for adding a light veranda or utility room, insignificant in its weight and massiveness. This option is distinguished by its ease of implementation and pace of construction.
The first step to pouring the foundation should be research papers for soil studies. This is what they do specialized enterprises, it is extremely difficult to do this on your own, and the costs for the services of these specialists are incomparably small compared to the cost of losing the entire extension.
After issuing recommendations on the type, depth of the foundation and the need to tie it to the main building, they begin marking on site. The contour is measured very carefully, observing the geometry of the corners, so as not to adjust the trench during work.
They begin to dig a trench from the very low angle, maintaining the required depth. It is best to immediately install temporary supports to prevent the walls from collapsing. When earthworks completed, a cushion of sand and crushed stone is placed at the bottom of the trench. A layer of sand 100-150 mm thick. It is compacted well, and the same layer of crushed stone is poured on top. Since we are building an extension to the house with our own hands, all work is carried out efficiently and conscientiously.
![](https://i1.wp.com/small-house.ru/wp-content/uploads/2016/01/kak-sdelat-pristroyku-k-domu-sovetyi-e-ksperta-02-220x162.jpg)
The construction will be relatively universal frame walls. The technology is little known to a wide range of the population, so many treat it with distrust, and completely in vain.
Popular frame walls
A frame wall is not a simple structure. It is complex and multi-layered. Those who want to use this particular method often do not know how to make an extension using walls of this design. The wooden frame consists of an upper and lower wall frame. Auxiliary beams and racks are used to obtain the necessary structural rigidity, and doors and windows are placed between the crossbars.
The finished wall frame is sheathed on both sides with boards, forming a void, which is filled with insulation, a protective membrane and, in mandatory, vapor barrier. A vapor barrier layer is required. It prevents moisture from getting inside along with warm air from inside the room. Wet insulation loses its properties, and in addition, moisture is very destructive to wooden base Houses.
The problem of insulation can be solved by all kinds of mineral and glass materials, which are now offered in a large assortment by the construction materials market.
The construction of frame walls begins by attaching horizontal framing beams to the foundation. This is usually done using metal anchors. It is especially worth mentioning that the waterproofing layer of the foundation must already be laid, and the lower beam must be attached on top of it. Next, the corner and load-bearing posts of the frame are mounted on the lower frame, which are fixed to provide rigidity with braces.
The top trim is laid on top of the posts, which are fastened with straight spikes. Sheathing and internal insulation produced from inside the house. Moving outwards, the installation sequence is as follows: first the inner lining, then the vapor barrier, glass or mineral insulation, and finally the windproof layer. The whole thing is covered with external cladding.
The outer cladding must have good qualities moisture protection, be resistant to wind and all kinds of weather conditions. Typically this material is “lining” or non-profiled planed board. They must be nailed horizontally. The “lining” is attached with the inner ridge upward, and regular board with overlap and overhang one above the other. This scheme allows you to reliably protect the inner layer of insulation from moisture, slanting rain and snowstorms.
When building an extension to a house, you can use almost any material. It is important to remember that some of them are toxic and unsuitable for use. internal lining. Fiberboards, plywood or drywall, will be an excellent basis for further improvement of the interior.
Roof construction
Typically, a single-pitch option is chosen for the roof of an extension. With this option, the angle of inclination should be at least 25-30˚. Having determined the angle of inclination, the timber is secured to the main part of the building. Bottom support The wall, its outer edge, or the laid floors of a new building will serve. The edge of the roof must protrude at least 300 mm. from the wall, for maximum protection from precipitation. After installing the rafters, the main roof is installed, if it is a rigid roof. When choosing flexible tiles Additionally, a base is laid in the form of plywood or similar material.
Floor installation and interior work
The choice of floor will be dictated by the purpose of the structure. For the residential option, insulation is required by installing wooden beams and laying insulation; it is also possible to install a heated floor. For a garage or storage room, a concrete floor is quite suitable. You need to approach this issue on a purely individual basis. The same applies to interior decoration.
Having studied the materials in this article, there should be no questions left about how to properly make an extension to a wooden house, since the choice of material and construction stages are similar and are suitable for such a construction.
One of the advantages of living in the private sector is the opportunity self-construction according to your own design - you can build a house of any size (naturally, within available area land plot) and then, if necessary, increase it in size. If the strength of the foundation allows, the house can be increased in height or, conversely, increased in length or width - so to speak, make an extension to it, which will be discussed in this article. Together with the site, we will look at the materials and technologies that will allow us to independently solve the question of how to make an extension to the house? And we’ll start by studying materials, where we’ll figure out which materials are best used and under what circumstances.

How to make an extension to a house: choosing materials
In general, there is one iron rule that is better not to break. It sounds like this: what the house is built from is what you need to make an extension to it from. At least, this was the case in the past, when the choice of building materials and technologies was limited to brick, other blocks and clay. Today, during advanced technological progress, things are a little different - there are technologies that make it possible to violate this rule, and rudely. Nowadays you can easily attach a brick building to a wooden house, cover it with the same material and get a solid-looking structure. In general, it is not at all necessary to become attached to the old building in terms of material.
Now, in more detail about the most popular materials, with which you can quite simply solve the question of how to make an extension to the house with your own hands?
- Blocks of various formats and bricks. There is no point in dividing them into separate subgroups, since the technology for using them is, in general, the same type - a foundation is erected, on which the walls of the extension are laid block by block, brick by brick. The only point that distinguishes this whole matter is the properties and qualities of the materials - this is important, and it is imperative to take them into account when choosing materials. Let's start with the classics - . Strong, durable material - considering it is quite expensive. Moreover, the brick is enough cold material, which will additionally have to be insulated, and this will add to the cost of the extension. In addition, this material requires a solid foundation. In this regard, it looks much more attractive - its price is a couple of times lower, the blocks are larger and the material itself is much warmer. Where the brick will need to be laid out in three rows, it is enough to lay the cinder block in two rows. Aerated concrete looks even more attractive - it is lightweight, and the question of how to properly build an extension to a house can be solved even on a shallow (0.5 meter) foundation. Moreover, it is a very warm and porous material, which, with a thickness of 200 mm, is capable of effectively retaining heat in rooms. After plastering, it acquires very decent strength, which makes the structure reliable. In principle, we can consider other block materials– for example, shell rock is often used; it has shown itself to be quite good in terms of preserving heat in rooms (popularly called sawdust concrete).

- . To date this is the most best option not only for extensions, but also for the construction of private houses in general - the essence of this technology is the production of wooden and metal frame followed by covering it like this sheet material, How . Insulation is placed inside the frame, which makes the structure very warm. By and large, this is now the cheapest technology, which, among other things, boasts simplicity and a very fast pace of construction. The only thing that a frame extension cannot boast of is its durability. Although, who knows - with proper technology and proper care, it can last for about a century. About how to do frame extension to the house, we'll talk a little further.
In addition to the options described above, you can consider the technology of building an extension using the monolithic concreting method. Moreover, it is not at all necessary to use real heavy concrete for these purposes - the best option in this matter may be the so-called slag concrete. Slag houses are very warm in winter and cool in summer - they are durable and can last for a very long time.
How to properly make the foundation of an extension to a house: features
The main problem in making the foundation of an extension is connecting the new and old foundations. If it is done incorrectly or not done at all, then no matter how you join the walls of two separate buildings, a crack will still appear at the place where they join. Moreover, end-to-end, with all the ensuing consequences - heat leakage, condensation formation and, as a consequence, the appearance of fungus and mold in this place. In general, it’s not very pleasant. That is why special attention must be paid to the following points.
![](https://i2.wp.com/stroisovety.org/wp-content/uploads/2016/06/kak-pravilno-sdelat-fundament-pristrojki-k-domu.jpg)
In principle, these three nuances will be quite enough to reliably connect two foundations together. Alternatively, if, of course, you can get to the bottom of the base existing house, the extensions can be added a little under it.
How to make an extension to a brick house: nuances of joining walls
Dock to a brick or any other block house frame structure not a problem at all - vertical beam wooden frame or the profile of the metal frame of the building is simply attached to the wall of the building using anchors and that’s it! There are practically no nuances here - except perhaps maintaining the vertical level of this beam and sealing the joint. The last operation is carried out either using polyurethane foam or using the so-called PSUL tape (pre-compressed sealing tape).
How to make an extension to brick house photo
Another thing is joining a brick or block building with a similar house. Here things are somewhat more complicated, and you cannot do without special embedded parts or ligaments. It is possible to ensure a reliable connection of the walls without ligating the blocks only by driving iron embedded parts every 4-5 rows of blocks. Holes are drilled in the wall of the existing building (two, one on each side of the block at a distance of 3 cm from the edge) - reinforcement is driven into them, which should protrude from the wall of the house by at least 30 cm. When it fits new block, the cement will reliably connect the two walls into a single whole product. As an option, again, you can use a hammer drill to make potholes, which, when paired with reinforcement, will provide a reliable connection between the two block walls with each other.

And in conclusion to the topic of how to make an extension to a house, a few words about connecting walls with a block or brick extension. This combination of buildings is also common, and it would be useful to know how they are connected. In fact, you will have to make a metal girth for the blocks - it is attached to the wall wooden house using powerful self-tapping screws and represents some semblance of a channel, into which a block or brick wall. By and large, this is the same option that is used to attach a wooden extension to a brick house, only exactly the opposite.

Building extensions to a wooden house with your own hands is becoming very popular in lately, as can be seen from the huge number of projects with photos. Indeed, owners of private houses are often faced with the question of expanding space, and the best solution in this case is an extension. Among other things, an extension can radically transform the appearance of the house, making it more modern, cozy and attractive.
Option for a closed glazed extension
Types of extensions by shape and purpose
Based on appearance and, accordingly, functional purpose, extensions are divided into several types:
- Additional full room in the house.
- Open/closed veranda.
- Porch.
Let's look at each type in more detail with their advantages and disadvantages.
Various options for extensions to a residential building.
Full room
IN in this case an additional full-fledged room is being built, suitable for year-round residence. It can also be used as:
- utility room;
- garage;
- pantry;
- winter garden;
- summer kitchen;
- additional bathroom;
- guest house.
An extension used as a garage.
Most often used for construction wooden beam, brick or foam block with insulation.
Advantages of this type:
- significant increase usable area Houses;
- ease of communication (electricity, heating) from the main building;
- ease of re-equipment of the room, if necessary, for another function.
Construction of an extension from wooden beams.
Well done, beautiful extension can advantageously complement the exterior of the house. However, there are also disadvantages to this solution. For example, you will need to make a reliable foundation and spend money on high-quality insulation, which will be reflected in the cost of the entire project.
Also, for the addition of a full-fledged room, you will need to allocate quite a lot of space, which is not always possible for owners of small plots.

Enclosed veranda
Usually this is an unheated room with walls made of brick or timber, completely glazed. Due to the lack of heating, it is used only in the warm season.
Spacious glassed room.
Design advantages:
- the ability to implement almost any design;
- glass buildings look very impressive and advantageous;
- in summer you can relax on the closed veranda even in strong winds and rain;
- glazing protects against annoying insects.
There are few disadvantages to this design, but they still need to be taken into account:
- a large glass area means the need for frequent and thorough cleaning;
- The glass-covered structure does not give that feeling of being on fresh air, which many expect from the veranda.
A fully glazed veranda looks very original and stylish.
Another example of a completely glass veranda in the photo:
A glass terrace can become a real highlight of the house.
Construction of a terrace and a house from different materials can also be turned into an advantage. For example, in the photo below, the extension is made of other materials in a different color scheme, but it looks simply magical:
A snow-white closed terrace near a gray house.
Open veranda
A simple, practical and functional frame structure, which has recently become very popular. Open veranda looks great in tandem with a wooden house.
Outdoor terrace with beautiful views of the lake.
Advantages of open design:
- much smaller financial investments for construction using minimal materials;
- the opportunity to stay outdoors;
- the need for a smaller building area than for a full-fledged residential room;
- ease of installation;
- functionality and convenience.
An open terrace with one glazed wall.
Among the disadvantages, it is worth remembering that the use is strictly seasonal. Moreover, in too cold summer weather, when strong wind or in the rain, staying on the veranda will be uncomfortable. In addition, insects will torment you in the evening.
The veranda adds completeness to the exterior of the house.
Porch
Looks like several support pillars and roofing material and serves to protect the space from rain and snow. The porch is the simplest, but at the same time the least functional option extension, which serves a largely decorative role. However, if you install chairs on it, coffee table, a small bench, a porch can easily replace a gazebo.
A miniature porch with a bench and an armchair.
Design advantages:
- ease of construction;
- low financial costs;
- no need for a solid foundation;
- transformation of the façade of the building.
Obviously, in bad weather conditions you won’t be able to relax on the porch, and it will only be possible to use it in the warm season. Together with little functionality, these are all disadvantages of this type extensions.
Spacious porch front door.
Most often, the porch is located on the front of the building, through which residents and guests of the house get inside. However, it is not necessary to build a porch at the front door. If you place the extension in the backyard, you will get a cozy enclosed patio. Space can be expanded comfortable furniture, table, hammock and turn it into a place for a summer dining room, playground, a space for friendly gatherings and romantic dinners.
The porch in the backyard of the house serves as a favorite place to relax.
Materials for building an extension
You can build a terrace or room from various materials- this is even with a wooden house structure modern materials will look harmonious thanks to the finishing.
When choosing materials for an extension, it is worth moving away from the common stereotype that the house and the extension should be made of the same material. Of course, an extension is a harmonious continuation of the house, but a combination of different materials can look more advantageous and interesting.
Most often, the following materials are used to construct an extension:
- Beam. Practical, environmentally friendly, aesthetic and very durable material. Thanks to special impregnation, the wood is resistant to pests, rot and fungus. When building from timber, it is necessary to have an expansion joint between the structures. The walls and roof are erected in the same way as the main living space.
- Brick. Natural, durable material for the construction of extensions.
- Foam block. Extremely common now, durable, affordable material with excellent thermal insulation properties. An additional advantage is fast construction premises thanks large sizes blocks. It is convenient to build additional rooms from foam blocks and closed verandas. The disadvantage is the mandatory need for exterior decoration due to the unaesthetic appearance of the blocks.
- Frame. This option is the least expensive in terms of finances and time resources. Using the frame you can build a terrace, veranda or porch. The method consists of making a wooden or metal frame, which is then finished with chipboard (OSB) boards and insulated special material(foam, mineral wool etc.). Due to their lightness, frame structures are excellent for the construction of two-story buildings.
- Polycarbonate. This material is used in the construction frame buildings. This material is extremely popular now due to the following properties: ease of use, lightness and strength, aesthetics, the ability to build any extension geometric shape. It can only be used for
An extension made of foam blocks does not require such a solid and powerful foundation (a columnar one is sufficient), but a brick and paving structure necessarily requires the laying of high-quality strip foundation to avoid distortions and deformations under the weight of the brick.
The roof of the extension, made of polycarbonate, provides high natural light to the extension.
Main stages of construction
Before you start building an extension to a wooden house with your own hands, it is worth studying in detail finished projects with photos and draw up a work plan. What it should include:
- location of the extension;
- type and design of the extension;
- type of foundation (based on the previous paragraph);
- list of necessary construction and finishing materials;
- supplying communications (minimum electricity);
- budget calculation (which includes, in addition to the cost of materials, also transportation costs and wages of employees).
When drawing up a project for a future building, it is necessary to indicate the following aspects: soil composition, level of freezing and moisture absorption, condition of the walls and foundation of the main building.
Laying the foundation
For verandas, a columnar type of foundation is most often used, and if the building is quite large, pillars need to be laid every 60 cm around the perimeter.
Work progress:
- Holes are dug to a depth of 100 cm. The depth of the holes must exceed the freezing depth of the soil.
- A cushion of layers of sand and crushed stone is placed at the bottom.
- The pits are filled with concrete mortar.
- Since the veranda is being built for a wooden house, we construct support posts from beams.

Construction of the frame
After laying the foundation, you can begin to build the frame of the building:
- First, the lower trim is mounted, the corners of which are fastened with a connection like “ dovetail" Dowels or nails are used to fasten the entire structure. The bottom trim can also be made double and the racks of the future veranda can be placed on it.
- Support beams are installed. At the wall of the veranda adjacent to the main room, the posts should be higher to construct a pitched roof.
- If the veranda should be closed, cross beams will determine the height of the windows.
- The installation of the frame is completed by installing the top trim.
Keep in mind that a roof angle of 45-60° almost doubles the consumption of roofing material. At this angle, the wind resistance of the coating is expressed, but, on the other hand, the roof is well cleared of precipitation.
Frame of a wooden veranda.
When using timber, its cross-section should be 10*10 or 18*8 cm, but if a log is used, then the cross-section should not be more than 12*12 cm.
Roof and flooring
For verandas attached to the house, pitched roofs are most often used. If the extension is located at the end of the building, it is advisable to use gable roof. Rafters and sheathing are attached to the top frame, onto which the roofing material is then laid.
Types of roofing for the roof:
![](https://i1.wp.com/mainavi.ru/wp-content/uploads/2018/07/pristroyka-k-kryiltsu-doma-foto.jpg)
Practical asbestos-cement slate roof.
To arrange the floor, logs with a distance of no more than 1 m are installed on the lower frame, on which a board is placed. Self-tapping screws are used for fastening. The board must be impregnated with a special solution to prevent fungal infections.
If the veranda is supposed to be open, the floor should have a very small angle for water to drain.
Finally, the building needs to be furnished with furniture, decor, and flowers to suit your taste.
After arranging the furniture and decor, the veranda looks very nice and cozy.
As you can see, to build a beautiful, modern extension building a wooden house with your own hands is actually not that difficult, focusing on ready-made projects and photos. If you have certain knowledge and skills, you can do it on your own and hire professionals. But in any case, an extension is a great opportunity to expand the space, transform the house and make it even more comfortable!
You can watch the video on how to build an extension:
Some time after the construction of a house, there is often a need to expand the usable area. The only way out of this situation is to build an extension to a wooden house. With proper design of the structure and selection of appropriate materials, this activity can be completed independently.
What do you need to know?
The construction of any object requires the creation of a project that is based on calculations. The construction of an extension to a wooden house is no exception. In this case, a design solution should be provided that would eliminate the occurrence of cracks. When choosing architectural form extensions, we must not forget about the need to create a unified complex in style.
In addition, it should be understood that the construction of the extension must be approved by the relevant organization and have all the necessary accompanying documentation. Otherwise, the constructed facility will be considered an unauthorized construction and in the future the developer will have to resolve the issue of legalizing it.
Types of extensions
Before starting the construction of an extension to a wooden house, you should study possible options structures and technological features their construction. After analyzing the information, the choice of materials and work technology is greatly simplified. This approach will allow the extension to be harmoniously connected to the existing building.
Canopy. This is the simplest extension design. It is necessary to protect the porch and people from sunlight and bad weather. In addition, under the canopy you can spend leisure time and receive guests.
The construction of a canopy does not necessarily require the construction of a powerful foundation. Installing pillars that act as supports can provide a fairly solid foundation. A frame is mounted to them, and the surface of the walls is designed depending on the taste preferences of the developer.
A wooden house may need an extension
Summer room. It is often built out of an extension. The room is intended for relaxation and serves as a place for friendly feasts. As the base of such an extension, a strip or columnar foundation. Wall material frame structure Plywood, boards or brick serve.
In order to create better illumination, the walls are made partially glazed. The roof of a summer room can have one or two slopes, and it is undesirable to make its structure heavier. Insulation or creation heating system in such a room is impractical.
Living room. The construction of a full-fledged living room implies a full construction cycle. When constructing the foundation, a block or monolithic structure is used. Brick, foam blocks or timber are used to build walls. When building a roof, a layer of waterproofing is required. The entire structure of the structure must also be properly insulated.
Kitchen. Arranging an extension indoors is quite a complex undertaking. This is due to the fact that in addition to the construction of a capital structure, all communications are required, including sewerage and ventilation.
Garage. This structure is built on a surface on which walls made of bricks or blocks are located. Also under construction reliable roof made of slate, metal tiles or corrugated sheets. In addition, the room must be well ventilated.
Porch. Often when installing various designs extensions, it is necessary to build a porch. The material can be concrete, timber or metal. If the porch is of significant height or has a turn, railings must be installed.
Installation features
The construction of an extension to a wooden house largely depends on how the room is intended to be used and whether it will be residential. If necessary capital construction needs to be built reliable foundation, separate from the base of the main building and the wall. It is also necessary to lay communications.
The main problem with building an extension is connecting it to the house. If there are omissions at this stage, then the formation of cracks in the structural elements of the structure is inevitable.
There are the following methods of connecting structures:
- Construction of an independent building. The method is used in the case of construction on moving soil. The base is arranged closed around the perimeter, having no points of contact with the main foundation. The gaps between the surfaces of the walls of buildings are provided with reliable hydro- and thermal insulation. The roof is constructed using a similar technology.
- Integration of the extension into the main structure. Carrying out work using this method is associated with certain difficulties. To connect structures, anchors or pieces of reinforcing steel are installed in the foundation of the house. Then, using welding, a connection is made to the frame of the base of the attached structure. At the end of this event, they begin pouring the foundation. monolithic type. Connecting the walls of two structures becomes possible when partial dismantling boxes at home. To integrate the roof structures, disassembly is carried out rafter system home and connecting it to the extension. Moreover, the fastening occurs both to the rafters and to the beams of the main building. After this, the roof covering is laid so that it represents a single surface.
When building a foundation for an extension, it is necessary to take into account the type of foundation under the house. This is due to the fact that different types of foundations on the same soil give different shrinkage. To prevent similar phenomenon The same base designs should be used.

Calculation and purchase of materials
At the design stage of an extension to a wooden house, the purpose of the object, its number of storeys and design features are taken into account. This allows you to make the optimal choice of material and draw up a construction estimate.
The following materials can be used for its construction.
timber
Using timber to build an extension to a wooden house is the best option. Moreover, the timber can be of any kind: glued, rounded or planed. Standardized material dimensions greatly simplify installation.
As a rule, timber is produced by specialized enterprises, each product has strictly defined dimensions, and the quality of the wood meets the standards. In the factory, the material goes through everything necessary steps protective treatment, which increases the service life of wood. If necessary, then finished product passes heat treatment to give wood a certain shade. Natural wood environmentally friendly clean materials, which has a beneficial effect on the health of people living in the house.
In addition to the described qualities, the versatility of the timber should be noted, since it can be used to create an extension not only to a wooden house.
If the cost of timber exceeds the construction estimate, then you should pay attention to other materials.

Frame extension
A good option from an economic point of view is the construction of a frame structure for the extension. It is characterized by the ability to carry out work on the existing foundation, which significantly reduces construction time.
The technology for constructing an extension involves the construction of a metal frame or wooden structure. To create the surface of the walls, the frame is sheathed on both sides using chipboards or OSB. Between them a layer of thermal insulation is placed from available heat-insulating material. There must be vapor and moisture insulation on top of the insulation.
The frame structure of an extension to a wooden house is easy to install and is available for self-assembly.
Brick
When using brickwork when constructing the walls of an extension to a wooden house, you can get a permanent structure. The material has good thermal insulation properties, so the extension can have both economic and residential purposes.
To maintain integrity architectural style It is recommended to move the brick extension out of sight. However, its location with back side buildings. Brickwork has a significant mass, so a reliable foundation is built that can withstand the loads from the walls.
The cost of construction in this case increases not only due to the rise in prices of materials and additional expenses for the construction of the foundation, but also due to the costs of finishing work.
Main stages of construction
Foundation installation
The base for an extension to a wooden house is selected depending on design features structures. If you plan to create a residential building, then construction is mandatory. At the same time, its depth should be the same as that of the main building. Reliable connection two structures occurs due to reinforcement.
The progress of work on the construction of the foundation occurs in the following order:
- carry out marking;
- dig a pit or trench of appropriate depth;
- formwork is installed;
- produce a bundle of reinforcement cage;
- pour .
At this stage, protection from moisture should be performed.

Wall installation
The construction of the walls of an extension is no different from the technology of constructing a house from timber or other lumber. At the same time, the resulting expansion joint must be sealed using polyurethane foam.
When using the same materials to build an extension and a house, the walls are connected using different fasteners. Dowels are made in the timber. Screws and plates are used, as well as staples to fix the walls.
Roof installation
In cases where the height of the extension is less than the height of the wooden house, the roof is made with a significant slope. This will allow precipitation to be removed without hindrance. In this case, the connection of both roof structures is not necessary.
When constructing a two-story warm extension It is recommended to connect the roofs of buildings. For this purpose, the roof of the main house is partially dismantled and the floors are tied together metal corners. After that, waterproofing is installed and the roof is laid. Must be organized unified system drainage

How to cut costs?
You can reduce the cost of building an extension to a wooden house if you take into account the following recommendations:
- the cost of timber is lower if purchased in winter;
- independent construction of the foundation will allow you to achieve savings of about 20%;
- use available materials;
- use frame method construction.
