Very often, you want to attach a veranda or a terrace to a finished home in order to increase the available living space and simply transform the look of a residential object. In such cases, an extension to a wooden house is being erected, the designs of which can be very different depending on the size of the new object and the materials from which it will be built.
An extension to a wooden house of a veranda and a terrace can be built in different ways in terms of design features. This is most often done in several ways:
- The annex is erected from the side and has a single roof with the house.
- The annex is located on the side, but under a separate roof.
- The veranda is located on the second and higher floor or in the attic.
Of course, most often the extension is made from the side of the house. The option with a common roof is more convenient and more profitable, but for this it is important that you can make a roofing system common with the house. As for the add-in, the process is not easy. So, first of all, it is important to take into account the possibilities of the foundation of the house, which may simply not withstand the load under the influence of the built-up terrace.
What material to choose
The veranda extension to a wooden house can be built using different materials. Most often it is a bar, log or frame technology, since these options look harmoniously against the background of the general exterior of the cottage. But no less popular are brick or foam block extensions. We note right away that each of the options has its own nuances in terms of construction. Let's consider the features of the construction of each material in more detail.
Bar extension
Is the most common material. This is due to the peculiarities of the material itself:- Its production is carried out in a factory, so the wood is of high quality.
- Due to special processing, the material is highly resistant to rotting and fungus.
- Environmental friendliness and naturalness are the main advantages of any type of timber.
But before making an extension, you need to solve a number of questions for yourself. The most important thing is the foundation of the future home. There are a lot of options for its creation, but any foundation must be firmly "tied" to an existing building. Ideally, an extension needs the same foundation as that of the house. Therefore, it is important to study the condition of the soil, its type, to think over what the load from the extension will be. After that, it is necessary to solve the second question: the veranda will be combined with the general perimeter of the house or will be erected as a separate structure. It is not easy to combine structures, since it will shrink, and even experts will not answer what it will be.
Frame extension
From the frame is a budget option, since significant investments in its construction are not required. In addition, the construction of a veranda or terrace itself will be much faster with minimal expenditure on materials. The construction of the structure is carried out on the basis of a frame consisting of a wooden beam or metal profiles. The frame is being erected along the entire perimeter of the future veranda.
Reading time ≈ 4 minutes
A private house needs expansion over time - there is a need to expand the kitchen, add a veranda or arrange an additional room. Therefore, the owner of the house has a question - how to make an extension to the house with his own hands? Below are the stages of construction using frame technology.
The advantages of wireframe technology
The frame extension to the house has important advantages:
- low cost and minimum amount of building materials;
- work is done quickly;
- there is no need to equip a massive foundation.
Schemes and drawings of the extension project are understandable to any novice builder. The technology is similar to assembling a constructor, but in the end you get a comfortable and cozy additional room.
Preparatory work
The construction of an extension to the house begins with preparatory measures. Carefully inspect the site for construction, remove all debris and vegetation from it, mark the area and stock up on the following materials and tools:
- metal pipes for supports;
- components for concrete mix - sand, cement, gravel;
- self-tapping screws, nails, metal corner for fastening;
- boards for logs 5 cm thick and 15 cm wide;
- perfectly finished boards for finishing the floor;
- natural wooden wall paneling;
- bar 50 mm;
- concrete mixer;
- hammer, screwdriver, building level, rope and circular saw;
- block house under a log for cladding an extension from the outside;
- metal roof tiles.
Be sure to provide a drainage system under the extension. To do this, tamp the ground under the veranda and make a slope at this place for water drainage. Below is a step-by-step instruction for the construction of an extension.
Step-by-step instructions for building an extension to a house
1. Installation of supports. Nail a wooden plank at least 5 cm wide to the wall of the house, which will become a support. Along the edges of the marked area for construction, install wooden structures - "rags". They need to be installed a little further than the marked area. Pull a strong rope over them. Check that the markings are correct so that everything is at right angles.
2. Dig a trench along the width of the foundation, one meter deep. Prepare a cement mixture of sand, gravel and cement with the addition of water. Make wood formwork. Begin to install the support pillars, make the distance between the pillars no more than 1.5 m.Pour a gravel cushion about 10 cm thick at the bottom of the trench. Saw the pipes in advance, and install them vertically in the pit, fixing them with boards. Next, fill the gaps between the support posts and the walls of the trench with the prepared solution. So that the vertical position of the pipe in the pit is not violated - fix the supports with spacers and wait three days for the solution to freeze. After it has hardened, the formwork can be removed.
3. Creation of the floor. At the next stage of creating an extension to a wooden house with your own hands, take log boards. Two boards are mounted to the supports with metal mounting angles at the end of the extension - place the rest between them. When installing lags, do not forget to check their horizontal position with a level. The transverse lags are mounted with 120 mm nails and grooves to the longitudinal part of the annex foundation.
4. Installation of the base for the walls and roof. Work begins by screwing the beams to the base of the floor using dowels and a hammer drill. The side rails are nailed to the walls. You can get acquainted with the video and photo of this work in our article. The stability of the structure is ensured by diagonal beams laid at the outer corners. Don't forget to mark the door and window openings. The whole structure is reinforced with transverse insert bridges. Outside, the base of the extension is sheathed with a block house. It is advisable to lay a layer of glassine on the boards of the sheathing before sheathing, it will protect the building from moisture.
5. Arrangement of the roof. After installing windows and doors, the roof is covered with metal tiles. Cover the place where the roof adjoins the building with a galvanized iron apron.
6. Internal work. An extension to the house with their own hands will soon be built, internal work remains. The walls and ceiling are sheathed with natural wooden clapboard. Before that, they can be insulated with penofol. To create a floor, you first need to make a rough floor. On the sides of the genital logs, a rough bar is laid, edged boards are laid on it. Insulation in the form of mineral wool is placed on them, and then proceed with the installation of the finished floor.
We hope that our instructions have helped you learn how to build an extension to your house. If you carefully study the sequence of work and properly prepare building materials and tools, as well as be patient, you can easily make a beautiful veranda yourself.
DIY video of the construction of an extension to the house
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 - they will live there. And what, that a person will also conduct any economic activity - no. In addition, sometimes there is an urgent need to increase the living area of the house. An extension made of foam blocks, a brick extension, a wooden one - the creation of these structures will help to solve this issue once and for all.
Types of extensions
The type of buildings is determined depending on what exactly should be in it. This can be a room, toilet, garage, kitchen, or whatever. By the way, in central Russia you can often find a structure in the form of a greenhouse, where 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 a building must be agreed upon, even if we are talking about wooden terraces or a veranda is simply attached to the house.
Project creation and selection of an extension location
Projects and construction of such structures involve the following stages:
As for the choice of materials, it is better to be guided by the following rule: it is necessary to create projects and build an extension from such materials that the house itself consists of.
Sectional structure of a frame house 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 far from always being observed.
Let's say a person wants to breed chickens, he needs a high-quality, windproof, warm brick extension. In this case, this option should be preferred, despite the fact that the house is wooden.
Options for the location of annexes to a standard wooden house Estimate calculation
Actually, the estimate itself is not so difficult to make, it is necessary to take into account the following:
An example of a veranda attached to a wooden house 
An estimate for construction must be drawn up immediately after the projects are ready, regardless of whether the terraces will be attached or just wooden household blocks. This will allow you to avoid unpleasant surprises in the future.
Erection of the foundation and connection of the foundation
Baths are often attached to wooden houses in Russia. Even the construction of an ordinary terrace for a wooden house involves the creation of a new foundation for it. The option with lengthening the old foundation disappears immediately: it is impossible to do this, but to connect both foundations into a single whole later is not only possible, but also necessary.
For example, even for wooden terraces, you will need to make exactly the same foundation as for the main house. So, first you need to decide on the type of the foundation itself.
General diagram of the device of the pediment of a frame house Actually, there are 3 options for the foundation that can be used as a base for an extension:
- Monolithic;
- Columnar;
- Ribbon.
The columnar foundation is used extremely rarely in Russia, since it can only be installed on very hard soils such as mountain ones.
It can be used, for example, for the construction of a gazebo, however, such structures are usually not attached to the house, but placed next to it. By the way, for a gazebo, instead of a foundation, you can take old tires - this will be quite enough.
Layout of the masonry 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 adding a garage to a wooden house As noted above, it is as easy as shelling pears to place any communications in the extension, because the room will adjoin directly to the house itself. What does this mean?
For example, it is enough just to lengthen the existing water supply, sewage or heating system - that's it, no foundation pits and exhausting welding work. The same applies to the laying of electrical wiring, which, probably, even the most careless worker can carry out with the help of a puncher.
It's another matter when it comes to really complex engineering systems. Let's say you need to run a branch from the main gas pipeline to the extension. Firstly, no one will let you do it yourself.
Arrangement of a veranda attached to the house Secondly, it will require, speaking without exaggeration, colossal spending. So it's worth considering. 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 extension 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 imply a solution to the problem with communication between the annexed structure and the rest of the house.
This problem has 2 solutions:
A covered terrace is a great option for an extension - An extension to a house from a bar can communicate with the house using a doorway made in the main wall of the house;
- The entrance can be carried out from the side of the street (an extension to the house from a bar allows you to easily 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 increasing. But there is one extremely important nuance: the approval process in this case can take many months, because you need to make changes to many documents.
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.
Cutting the opening in the load-bearing wall should be done with utmost care!
If there is not enough money and there is no desire to go through the bureaucratic circles of hell, then the option with an entrance from the courtyard will not be so bad. Moreover, in terms of cost, it will come out much cheaper.
Video
You can watch a video on how to make a frame extension to a wooden house.
The construction of an extension allows you to significantly expand the area of a wooden house and make it more solid in appearance. Similar structures are assembled from a variety of materials. This can be, for example, wood, brick or gas blocks. Of course, when building an extension, certain technologies should be followed. We will talk further about how such structures are assembled correctly.
Drafting a project
When planning such a structure as an extension to a wooden house, first of all, you should decide:
- With material for walls, foundations and roofs. A timber frame or log structure is usually attached to a wooden building. Sometimes the walls are made of bricks or gas blocks. It is better to choose the roofing material for the extension the same as the roof of the building itself. In any case, you should try to make sure that the colors of the coating sheets are at least in harmony with each other. The foundation for the extension is chosen of the same type as the foundation of the building itself.
- With the dimensions of the structure. The extension area should not be more than 2/3 of the house area. Otherwise, the building will look awkward and ugly. The house looks most harmonious when the area of the new building is 1/3 of the old one.
The addition of a terrace to a wooden house, a veranda or a closed capital structure is carried out in such a way that their roof is located just below the main roof. Of course, the angle between the two should not be negative. Otherwise, snow and water will accumulate at the junction.
Erection of the foundation
The markup for such a structure as an extension to a wooden house is done in the usual way - using a level or using the "Egyptian" triangle method. The foundation of the extension should be laid at the same depth as the base of the building itself. Rigidly concrete tapes of houses and outbuildings are usually not tied together. Otherwise, when the new structure shrinks, cracks may appear at the junction. However, sometimes the foundation of an extension to an existing one is nevertheless tied. In the event that cracks subsequently appear, they are simply covered with cement mortar.
The choice of the type of mating depends mainly on the type of soil and wall material. If strong shrinkage is expected, it is better not to tie the foundations. The base for the extension is poured in the usual way: with a sand cushion, waterproofing and reinforcement.
Frame constructions
This is the cheapest type of extension with good performance. Such structures are erected literally in a few days and do not shrink at all. Even an inexperienced private builder can assemble a very convenient and aesthetic frame extension to a wooden house. The designs of such structures are unusually diverse. If necessary, using this technology, it will not be difficult to build an ordinary summer extension-veranda, an insulated residential structure, a workshop, a kitchen and even a boiler room.
Construction features
The foundation is pre-established within a month. When erecting under frame walls, anchor bolts should be poured into it in increments of about 1.5 meters. The lower harness is fixed on them. Its corners are usually connected using the "half-tree" method. A frame extension to a wooden house will turn out to be even more reliable if metal rods 40 cm long are poured into the foundation at the corners so that they protrude 20 cm above the surface.In this case, holes are drilled in the strapping beam in the appropriate places.
The assembly of the frame begins with the installation of corner posts. Holes are drilled under the rods-pins in their ends. Next, intermediate racks are attached (with a step of 1.5 m). Fixation is usually made on galvanized steel corners. In order for the pillars not to deviate from the vertical during construction, they should be fastened with temporary jibs. The next step is to start assembling the upper strapping. It is also fastened to the corners, and in the corners - by the "half-tree" method.
The construction of such a structure as a frame extension to a wooden house is continued by fixing the lags to the beam of the lower strapping and sheathing the floor with an edged board. The floor beams are fixed to the top. After that, you can start wall cladding. First, from the side of the room, a vapor barrier membrane is attached to the pillars of the frame (in blocks). Next, the inner lining is performed. Then, between the pillars from the side of the street, a heater is installed (if the extension is winter). At the final stage, the structure is covered with a waterproofing film and sheathed with clapboard, board or siding.
Erection of cobbled walls
Such an extension to a wooden house looks beautiful and is durable. It is also not too difficult to build, but it costs more than a frame one.
The lower crown of such an extension is laid on a waterproofed foundation in the same way as the strapping of a frame structure - that is, with fastening to an anchor. Logs are fixed to it, and the floor is covered with a board. The walls are assembled in the usual manner. The corners can be joined by "butt-joint" or "half-tree" methods.
Expansion joint
A very reliable extension to a wooden house is obtained from a bar. Projects can provide for the construction of this material as open verandas and capital heated buildings. However, in any case, one simple rule should be observed: you cannot rigidly connect the walls of the extension with the house right away. The timber after erection gives a very strong shrinkage. Therefore, an expansion joint should be arranged at the junction of the walls. This is very easy to do. On both sides of the wall of the extension (from the side of the room and the street), beams of 100 x 100 or 50 x 50 mm are nailed to the house itself. All gaps are filled with some kind of plastic material - for example, mastic or special sealant.
If necessary - at least two years after construction - an extension to a wooden house or any other, made of timber, can be attached, including rigidly. In this case, either staples or special plates with screws are usually used.
Brick construction
Wooden outbuildings are, of course, beautiful structures and are just perfect for a suburban residential building. However, many owners of cobbled and log houses still prefer to build more durable and capital structures of brick. Such an extension is assembled in the usual way with bandaging the seams, the thickness of which can be 1-1.5 cm.
Of course, a rigid connection between the walls of the extension and the house should not be done either. The brick structure is very heavy and sinks significantly. Therefore, the interface between the walls is simply arranged end-to-end with the filling of the seam with polyurethane foam, or in the same way as in the first case between the beams.
Features of the construction of roofs
Thus, the addition of a veranda to a wooden house or more capital structure is usually carried out without rigid fastening of the walls. The same rule should be observed when assembling the roof. The roof of the extension can have any shape, but most often the usual shed structure is erected.
At the first stage, the ceiling is hemmed from edged boards or plywood. Further, any vapor or waterproofing material is laid on top of it. Then - insulation. After that, the resulting overlap is sheathed with a board from above.
The rafters are attached on one side to the top harness or Mauerlat. In this case, metal corners or fastening "in the knot" with preliminary cutting of the seat nests are used. From the side of the house, on the harness, you can either simply put a wide beam on the edge, or install it on the racks. A waterproofing material (with a slight sag) is stretched onto the rafters and the crate is stuffed. Then the roofing sheets are attached. The joint between the roof of the extension and the wall of the building can be sealed with mastic or foamed.
- The junction of the foundation of the extension and the base of the house, in the event that they are not rigidly fastened, should be laid with a strip of roofing material.
- All wooden elements of the building are pre-treated with an antiseptic against fungus and a composition that increases the fire resistance of the material.
- The cobbled annex is best erected during the cold season. In winter, this material shrinks less.
- When assembling an extension of any type, it is worth using only galvanized fasteners. This will extend the life of the entire structure.
The construction of outbuildings, as you can see from the article, is a completely simple matter. The most important thing is to comply with all the required technologies. In this case, you will get a reliable, durable and convenient structure.
Without first obtaining permits, an extension to the house with your own hands is an illegal increase in the area of \ u200b \ u200bthe dwelling. It cannot be legalized in fact, if it violates the interests of neighbors, is built of materials that do not meet the norms of SNiP, and is located near underground utilities. The optimal solution is the design before the start of work with preliminary design by specialists.
An extension to the house is an excellent solution for expanding free space in a suburban dwelling of any type. It is important that all construction work can be done independently.
Of course, this will require certain construction skills and knowledge of work technologies, but there is nothing particularly difficult in this. The help of specialists may be required at the design stage of the structure, as well as when supplying communications inside the structure. In addition, certain problems often arise when legalizing an extension in the regulatory authorities.
The annex can perform a variety of functions.
Most often, an extension is built to form an additional room, summer kitchen, garage, veranda, terrace, awning, porch. There are a huge number of options - everything will depend on personal requirements and wishes. Of course, it will be very difficult to build something from a technological point of view, but often all construction is done by hand.
The main thing here is to correctly complete the construction of the foundation, walls, roof, insulate and isolate the room from moisture, and also correctly attach the new base to the old one.
Types of outbuildings for country houses
Before starting any construction work, it is necessary to clearly determine the type of construction, because an extension to the house can only be made if there is a clear plan and project. There are several of the most common types of extensions in our country:
Canopy
This is the simplest and least expensive extension for a country house from all points of view. The main functional task of such a structure is to ensure the protection of people and things located under a canopy from sunlight, rain and other precipitation. It will be good to rest under such a canopy in the warm season and have lunch, or you can park the car.
Carport.
An important advantage of the canopy is that the construction of the foundation is not required, because the support pillars (made of metal, wood, concrete) will act as the base. The canopy frame is fixed to these supports.
Summer room
To form a summer room, more capital construction will be required than in the case of a canopy. Such rooms are intended for relaxation in the warm season, gatherings, reading books, etc. Naturally, a foundation device is required.
It is recommended to use a columnar or strip base, depending on the type of building material and the dimensions of the room. Planks, foam concrete blocks, frame panels are usually used to create walls. For better illumination, the walls and roof, in whole or in part, can be made of glass.
Summer room.
Such an extension usually has a pitched or gable roof. It is recommended to use the lightest roofing material. Installation of heat-insulating materials, as a rule, is not carried out, because such premises are not used in the cold season.
Living room
Before attaching a room to the house, it is necessary to complete all the required calculations and draw up a project. In this case, a thorough approach will be required, which implies the construction of the foundation, capital construction of walls and roofs, installation of waterproofing and heat-insulating materials, and the supply of all necessary communications.
Warm living room.
Particular attention is paid to the insulation of the premises, so that it was possible to live here in the winter without spending a lot of energy on heating.
Kitchen
As a rule, extensions are not intended for kitchen equipment. Such a structure must be capital, therefore, it must be insulated as efficiently as possible.
Wooden kitchen.
It is possible to build such an annex correctly only with the use of a high-quality project created by professionals, because the kitchen needs all communications: sewerage, water supply, electricity, gas, ventilation system. This, of course, leads to serious financial costs, for which not everyone is ready.
Garage
The use of an extension for a garage device is a very common trend in recent years. The garage will require the construction of a strip or monolithic foundation, and for the construction of walls, foam concrete blocks or bricks are usually used.
Two garages.
The roof, in most cases, is made of profiled sheet or metal, slate or roofing material. Obligatory communications for the garage are ventilation and heating.
Connection of an extension with a country house
Many people take a long time to choose where to attach a new room to their home, so that it is easier to connect it to the main structure. Here you have to choose from two options:
- Independent facility. In the event that complex soil conditions are observed on the terrain (for example, heaving soils or a high level), then it is recommended to build an independent structure that will not be connected to the main house in any way. In this case, the extension and the main structure do not have points of contact, so they do not depend on each other. At the same time, the minimum possible distance is observed between the two buildings, which is a technological gap, which must be filled with heat-insulating and waterproofing materials.
- Introduction of an extension to the structure of the old building. Such a solution implies a certain laboriousness, because the construction will imply the observance of all the necessary technologies and the conduct of many calculations and studies. First of all, it will be necessary to correctly build and insulate the foundation, which must be correctly connected to the base of the country house. This is usually done with reinforced rods. The walls and roof of structures are connected using approximately the same technology.
Features of the construction of a roof for an extension to a house
The roof of the extension to the house can have any shape - here again everything will depend on the requirements and wishes of the owners. At the same time, most often suburban homeowners choose a pitched roof, because it is simple to perform, it is easy to insulate it on its own, it goes well with other types of roofs that the main structure may have, and also removes precipitation well, not allowing the entire structure to experience additional load.
In order for precipitation from the roof of the extension to flow down in normal mode, the design of the roof implies a roof slope of 20 degrees or more.
In addition, special attention should be paid to the establishment of a roof annex under the roof of a country house. If everything is done correctly, the wall located between the extension and the country house will be protected from water ingress through the joint between the two structures. In addition, the roof of the extension should be extremely harmoniously combined with the roofing material of the main building and harmoniously fit into the exterior of the building, without standing out from the general background.
In the design process, it is very important to correctly calculate the load that the roof structure will give. Consider the weight of the rafters, roofing material and other structural elements used in the construction of the roof.
It is important to understand that an extension to a house on screw piles or poles is not designed for too serious loads, unlike a monolithic or strip concrete foundation. You also need to insulate the roof (you can insulate it using any suitable thermal insulation materials, which it is recommended to cover with waterproofing on top).
How to legalize construction?
Building an extension to an old or new country house is half the battle. Any additional premises erected on the land plot must be documented and obtain permission to carry out construction work from the regulatory authorities.
An extension to the house with your own hands can be done as you like - no one will force you to invite builders, however, the suburban homeowner must present a competently drawn up project of the building to the employees of the controlling services.
The procedure for processing all the documentation for an extension to an old country house usually takes from several months to a year.
An interesting point - you can start collecting documents and obtaining a building permit after all the work has been completed. This is permitted by applicable law.
At the same time, when considering the documents, the employees of the supervisory authority may have some claims that will have to be corrected without fail (for example, the location of the building relative to underground utilities or the use of unsuitable building materials).
Consider buildings to the house and not annexes
Pergola is the simplest structure and a great place to relax.
The barbecue is a great place for receiving guests and celebrations.
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 - they will live there. And what, that a person will also conduct any economic activity - no. In addition, sometimes there is an urgent need to increase the living area of the house. An extension made of foam blocks, a brick extension, a wooden one - the creation of these structures will help to solve this issue once and for all.
Types of extensions
The type of buildings is determined depending on what exactly should be in it. This can be a room, toilet, garage, kitchen, or whatever. By the way, in central Russia you can often find a structure in the form of a greenhouse, where you can grow fruits and vegetables even in winter.

Indeed, in this case, all the necessary engineering communications can be easily extended from the house. Of course, the construction of a building must be approved, even if we are talking about wooden terraces or a veranda is simply attached to the house.
Project creation and selection of an extension location
Projects and construction of such structures involve the following stages:
As for the choice of materials, it is better to be guided by the following rule: it is necessary to create projects and build an extension from such materials that the house itself consists of.

Actually, the estimate itself is not so difficult to make, it is necessary to take into account the following:
An example of a veranda attached to a wooden house
An estimate for construction must be drawn up immediately after the projects are ready, regardless of whether the terraces will be attached or just wooden household blocks. This will allow you to avoid unpleasant surprises in the future.
Erection of the foundation and connection of the foundation
Baths are often attached to wooden houses in Russia.
Even the construction of an ordinary terrace for a wooden house involves the creation of a new foundation for it. The option with lengthening the old foundation disappears immediately: it is impossible to do this, but to connect both foundations into a single whole later is not only possible, but also necessary.
For example, even for wooden terraces, you will need to make exactly the same foundation as for the main house. So, first you need to decide on the type of the foundation itself.
General diagram of the device of the pediment of a frame house
Actually, there are 3 options for the foundation that can be used as a base for an extension:
- Monolithic;
- Columnar;
- Ribbon.
The columnar foundation is used extremely rarely in Russia, since it can only be installed on very hard soils such as mountain ones.
It can be used, for example, for the construction of a gazebo, however, such structures are usually not attached to the house, but placed next to it. By the way, for a gazebo, instead of a foundation, you can take old tires - this will be quite enough.
Layout of the masonry extension from foam blocks
For capital buildings and garages, reliable and durable foundation structures are needed. Mostly prefabricated and monolithic tapes or monolithic slab. When using pillars and screw piles, it is imperative that the grillage is strapped, and to protect the space under the floor, it is taken from the cladding with basement siding with basalt mineral wool insulation or other similar heaters. At the top of the foundation, horizontal waterproofing from roll-up waterproofers (glass-fiber, waterproof, rubemast or roofing material) is required.
A good option is a frame extension to the house. The frame is constructed of wooden blocks filled with insulation (for example, mineral wool boards) and cladding with thick moisture-resistant plywood, OSB boards or other materials. The attached building can be made with window openings. The doorway is more convenient than the internal one, which allows passage to the attached part without going outside. But the device of an entrance directly from the street is also permissible.
The roof is most often arranged with a pitched roof. It is important to ensure that snow cannot accumulate at the abutment point, therefore the roof is made with an angle of inclination ≥ 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), wooden, faced with porcelain stoneware or tiles. Warm floors are often arranged.
It is recommended to build garage walls from non-combustible products (bricks, concrete or lightweight concrete blocks) with overlapping with reinforced concrete slabs or corrugated board. It is imperative to provide a number of ventilation holes.
How to attach an extension to a house
The connection of an existing building with an extension is one of the most critical moments of construction. Failure to comply with construction technologies in the abutments will inevitably form cracks with opening 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.
The attachment of the attached part is carried out in the following two variants:
- With an expansion joint without direct contact between foundations, walls and roofs. Recommended for problematic soils (peaty or clayey). A gap is provided between the structures, which is later filled with elastic heat and waterproof materials. It is permissible to lay a board treated with several layers of bituminous mastic. The resulting seam is closed with decorative inserts. It is imperative to eliminate the possibility of the formation of "snow bags" on the roof at the junctions.
- Inclusion of all constructs in joint work. The new foundation is being built at the same depth as the existing one. It is used for foundations made of soils that are not subject to heaving. The contacting surface of the old one is cleaned of soil soil, a layer of waterproofing and a notch is made using a perforator. Reinforcing bars are tightly driven into the drilled holes and the holes are sealed. The resulting embeds are welded to the reinforcement cage of the annex foundation, and concreting is performed with careful 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 pulled together with steel bolts or studs with double-sided threads, complete with wide washers, nuts and locknuts. To mate the roof, it will be necessary to remove part of the roofing and joint fastening of 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 erect a common rafter system or replace with longer elements.
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, rafter 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 possible nuances of future construction and to ensure that one is secured against possible administrative sanctions.
Advantages of an extension compared to a detached building
- Reducing the scope of work on the supply of engineering communications (electricity, water supply, heating, sewerage, ventilation).
- Less material consumption and construction cost, since at least one existing wall is used.
- Rational use of the territory without cluttering up with additional buildings.
- Additional insulation that prevents cold air from entering directly into the house with a decrease in heat losses.

An extension to a wooden house is a great way to increase the area. Projects of such structures are striking in their variety and scale. After choosing a suitable project, you need to prepare special materials. An additional extension will come in handy when creating a kitchen area, or a luxurious terrace. Any room can be built independently, but it is necessary to choose the right type of building.

Extension to a wooden house: projects of structures from various materials
After some time after construction work, it may be necessary to increase the usable area. A wonderful way out can be the creation of an extension to a wooden house. Projects of various structures can be viewed in the photo.
Choosing the architectural form of the structure, do not forget about creating a single ensemble in style. Such a structure requires special documentation and permission. Before construction work, it is necessary to study the technological features and design options.
The following extension options are worth considering:
- Simple designs include either a dining area. It is used for weather and sunshine protection. You can have picnics and receive guests under the canopy. For its construction, a strong foundation is not required. Pillars are installed as supporting supports, to which the frame and the intended wall surfaces are attached.
Such structures are often erected from logs, beams, foam blocks, and also from bricks. Frame technologies are often used.

Extension to a frame house: design and installation features
When making an extension to a house from a frame, significant costs will not be required. This is a budget option. The construction is made on a frame basis, which consists of beams or strips made of metal. After the installation of the frame structure, the walls are clad on both sides. In this case, OSB or chipboard plates are used. Heat-insulating material is placed between the plates. It can be expanded polystyrene or mineral wool.
In terms of thermal insulation properties, frame structures are not inferior to more solid stone or brick buildings.
Construction work is carried out in several stages:

An extension to a house made of foam blocks: photos of interesting projects
You can build an extension to the house from foam blocks.
This design is in demand due to the following features:
- The material has an affordable price.
- For the installation of the structure, it is not necessary to mount a complex and expensive foundation.
- The elements retain heat well. This is possible due to the porous structure and low density index.
- Foam blocks are produced in overall dimensions, which affects the speed of construction.
For structures made of foam blocks, a special foundation is required. It can be a strip or monolithic base. High-quality waterproofing is required. Construction work starts from one selected corner. After installing two rows. This is necessary to ensure better adhesion of the elements.
Extension to a wooden house from a bar: the nuances of installation and style features
A beautiful and solid extension to a wooden house can be made from a bar. Individual projects and photos can be found on the Internet.
The material has the following features:
- The production of timber is carried out according to factory technologies.
- The surface is treated with a special compound that protects against fungi and decay processes.
- Naturalness and high environmental friendliness are considered important advantages of the material.
The extension must be connected to an existing building. Usually, the same foundation is made for the structure as for the main building.
A separate foundation and a special wall should be created for the living space. The void and gaps between the two walls are blown out with polyurethane foam. This will prevent damage to the building wall when the new extension shrinks.
A more economical option for a foundation is a pile foundation. The walls are erected from profiled beams. After installing the first row, the surface of the tree is treated with antiseptic compounds. Then lags are mounted on it. Voids and cracks are filled with special heat-insulating material.
Each row is secured with wooden dowels. The installation of corner zones requires special attention. For this, logs with a protrusion and a groove are used for a stronger grip.
For your information! Reinforcement is applied to join the two foundations.
Before starting construction, you should take into account some of the nuances of installing an additional structure to the main structure. The length of the new structure must be in harmony with the wall length of the main building site. The width of the additional structure can be any.
The extension does not have to be adjacent to the wall where the entrance to the house is. The exit to the spacious veranda or kitchen area can be from the living room. If a bathroom is planned in the additional structure, then the exit can be performed from or. The front or end part of the house is considered a suitable location for the structure. The choice and amount of material depends on the type of future structure.
