Most projects individual houses provide only a residential part without additional outbuildings. Over time, residents, if available free space near the house, there is often a need to expand the structure with your own hands or with the involvement of qualified specialists. This may be due to a variety of reasons, for example, an increase in the number of residents, the purchase of a car that will require a garage, and other circumstances. An extension is an auxiliary part of a building that is adjacent to its main walls on one or more sides.

Types of attached buildings

The structure can be:

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

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

Necessary approvals

A project for an extension to a private house can be ordered from specialized design organizations or developed independently. To change the structure of a building, it is necessary to obtain a building permit from the local administrative authorities, which is necessary, as is the case for the construction of the main house. The project must be coordinated with the Sanitary authorities. and fire supervision, utility department. If the distances from the border with neighboring areas, regulated by building codes, written consent of the neighbors is required, preferably notarized. The illegality of the construction of an extension is also recognized in the absence of written consent of all co-owners of the building to carry out the work.

It should be borne in mind that a permit to carry out work is issued only if the rights to own a land plot and a house are registered in Rosreestr and taken into account in the state cadastre. In the absence of the necessary approvals, the structure may be declared illegal and subject to demolition. It is not necessary to obtain permission to build simple sheds or porches.

Structures and materials for the construction of the superstructure of buildings

The added part must fit harmoniously into general interior Houses. A two-story extension to the one-story building, which will also significantly complicate construction. It is recommended to use the same materials from which the main structure is constructed for the construction of walls. For an extension to wooden house apply wood and brick brick. You can use foam or aerated concrete blocks, and for a harmonious combination with the structure of the house, clad it in wood or brick. A high or turning porch, as well as open verandas and terraces, must be framed with railings.

It is advisable to build the foundation of a major extension to an old house of the same type as the one existing under the main building. Of course, to build a simple shed, porch or open veranda there is no need for a strong foundation. In most cases, a device is sufficient columnar base with a shallow depth or screw piles.

For permanent buildings and garages, reliable and durable foundation structures are needed. Mainly prefabricated and monolithic tapes or monolithic slab. When using pillars and screw piles, it is necessary to tie it with a grillage, and to protect the space under the floor, cover it with basement siding with insulation made of basalt mineral wool or other similar insulation materials. At the top of the foundation it is necessary horizontal waterproofing from roll waterproofing materials (glass insulation, waterproofing, rubemast or roofing felt).

A good option - frame extension To home. The frame is constructed from wooden blocks filled with insulation (for example, mineral wool boards) and lined with thick moisture-resistant plywood, OSB boards or other materials. The attached building can be made with window openings. Doorway The internal one is more convenient, which allows access to the attached part without going outside. But an entry device directly from the street is also acceptable.

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

The floor, depending on the purpose of the room, can be concrete (mainly in garages, workshops and storerooms), wooden, lined with porcelain stoneware or tiles. “Warm floors” are often installed.

It is recommended to construct garage walls from non-combustible products (brick, concrete or lightweight concrete blocks) covered with reinforced concrete slabs or corrugated sheets. It is imperative to provide a number of ventilation holes.

How to connect an extension to a house

Connecting an existing building with an extension is one of the most critical moments of construction. In case of non-compliance construction technologies cracks inevitably form at the junctions, opening up to large gaps. This is caused by the difference effective loads and the complete absence or slowdown of settlement of the foundation of an old house.

Connection of the attached part is carried out in the following two options:

1. With an expansion joint without direct contact between foundations, walls and roof. Recommended for problem soils (peat or clay). A gap is provided between the constructs, which is later filled with elastic heat and waterproofing materials. It is permissible to lay boards processed in several layers bitumen mastic. The resulting seam is covered with decorative inserts. It is imperative to eliminate the possibility of the formation of “snow bags” on the roof at the junction points.
2. Inclusion of all constructs in working together. The new foundation is laid at the same depth as the existing one. It is used on bases made of soils that are not subject to heaving. The contacting surface of the old one is cleared of soil and waterproofing layer and a notch is made using a hammer drill. IN drilled holes The reinforcing bars are driven tightly and the holes are sealed. The resulting embedded parts are connected by welding to reinforcement cage foundation of the extension, and concreting is carried out with careful compaction of the mixture using an internal vibrator. Brick walls connected in the same way. The rods are placed every two rows in the seams of the new masonry. Wooden structures are fastened with steel bolts or studs with double-sided threads, complete with wide washers, nuts and locknuts. To match the roof, it will be necessary to remove part of the roofing and jointly fasten the rafters and beams of the house and the extension with the addition of new additional nodes and racks. In some cases, it may be necessary to build a common rafter system or replacement with elements of longer length.

The second option is more complex, labor-intensive and costly, although it cannot be guaranteed that the joints will not come apart over time.

Depending on the design, materials existing house and the purpose of the attached premises, the foundation type, material and thickness of the walls, rafter system and roofing materials for a new building.

Before deciding how to build an extension, you need to provide for all possible nuances of future construction and guarantee to protect yourself from possible administrative sanctions.

Advantages of an extension compared to a free-standing building

• Reducing the amount of installation work engineering communications(electricity, water supply, heating, sewerage, ventilation).
• Less material consumption and cost of construction, since at least one already existing wall is used.
• Rational use territory without cluttering with additional buildings.
• Additional insulation, preventing cold air from penetrating directly into the house and reducing heat loss.

Some time after the construction of a house, there is often a need to expand 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, it should be provided that constructive solution, which would eliminate the occurrence of cracks. When choosing the architectural form of the extension, we must not forget about the need to create a complex that is uniform 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. Roof summer room It can be with 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 a foundation, use block or monolithic structure. 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 capital construction is necessary, it is necessary to build 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 structural elements construction 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 to pour the monolithic type foundation. Connecting the walls of two structures becomes possible when partial dismantling boxes at home. To integrate the roof structures, the rafter system of the house is dismantled and connected 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 foundations on the same soil exhibit different shrinkage. To prevent this phenomenon, identical base designs should be used.

Construction of an extension

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 that increases the service life of wood. If necessary, the finished product undergoes heat treatment to give the 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.

The most difficult thing is to connect the extension to the house

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 metal frame or wooden structure. To create the surface of the walls, the frame is sheathed on both sides using chipboard or OSB boards. Between them is placed a layer of thermal insulation made of 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 on the rear side of the building is not excluded. 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 increase in the price of materials and additional costs for constructing 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 of 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.

Light extension on a columnar foundation

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 the structures. 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. A unified drainage system must be organized.

It is better to make the roof from the same material as the main building

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.

Proper construction of extensions for various purposes can not only expand the residential part of the house, but also improve it appearance and protect against wear. The construction of a veranda adjacent to the house, regardless of the type of structure, requires careful development of the project, with the determination of materials and construction technology.

Proper execution and approval project documentation in government agencies will not only insure you against problems with the law, but will also help you draw up a plan and estimate for the structure.

Design

A typical veranda is a roofed frame structure built on a strip or column foundation, with glass or half glass walls. The statement that the veranda should be built from the same materials as the main building, with the emergence of new styles and fashion trends in architecture, has lost its relevance.

In the photos below - ready-made solutions verandas attached to the house, with different principles compatibility. In some cases, the new extension is made of the same materials and is completely combined with the house, in others the new is combined with preservation common elements– roofs, beams, etc.

There are also projects in which the original design of the extension introduces a new architectural touch, updating the exterior.

When choosing materials and construction technologies, you should also take into account the parameters of proper ventilation, moisture resistance and thermal insulation. With full glazing, it is necessary to provide opening segments for ventilation.

If you are building an open veranda, or, as it is also called, a summer terrace, you need to take care of the frost-resistant lining and the slope of the floor towards the site.

Designs with removable frames are optimal for year-round use. Installing large sliding doors will also allow the building to be used in a dual-mode version.

In a typical project, the veranda area is rectangular and ranges from 10 to 15 sq.m. For smaller areas it will be too cramped; for larger ones, additional reinforcement for the roof will be required. Polygonal and semicircular foundations are also possible.

According to its location, the veranda can be corner, end or facade. An original solution can be considered the construction of a terrace along the entire perimeter of the house, which can have glazed, open and closed areas for various purposes: they can accommodate a hallway, a recreation area, and a large storage room.

Foundation

The foundation of terraces and verandas attached to the house must fit tightly to the main building, but at the same time have independent supports.

A strip foundation is suitable for large and heavy structures; in all other cases, a columnar foundation can be erected. When pouring concrete, you need to leave a gap of 3-4 cm with the main wall, which will subsequently be filled with waterproofing foam.

At the first stage of preparation for construction, the soil is cleaned and compacted. Then, for the pillars, corner holes are dug along the depth of the house foundation (about 1 m on average), a cushion is made of crushed stone, gravel and sand, onto which concrete is poured.

After setting, supports made of asbestos or metal pipes are inserted. Can also be used concrete pillars or brick. The same method is used to lay high piles for buildings adjacent to the second floor level.

Depending on the area and weight of the terrace, intermediate posts may be needed, installed every half meter.

For a strip foundation, a 30-50 cm trench is dug, the formwork is placed 15-20 cm higher. Metal reinforcement bars or reinforcing mesh are placed into the soil. Concrete is poured onto a layer of crushed stone and sand.

Wood frame

The frame is assembled from beams or logs with a width of at least 12 cm, which are covered with a waterproofing layer. For the strength of horizontal knitting, experts recommend using fastenings in the foot, the surface of the connection will be at an angle. Vertical posts are secured with diagonal interceptions.

At the final stage, the wooden frame is covered with rafters for the roof. For cladding you can use plywood panels, chipboards, etc.

Construction wooden veranda- the best budget solution in terms of prices for materials, but when choosing this type of construction you need a professional approach and knowledge of the nuances of construction from wooden beams.

Other materials for verandas

The foam block structure is erected on a strip foundation. This type of masonry is easy to do yourself. The laying is carried out using a special glue, with the seams bandaged for strength.

When finishing, internal and external waterproofing layer, plasterboard finishing, wooden shields, moisture-resistant wallpaper and paints. External surface can be faced with ventilated facades.

The construction of the structure is made of polycarbonate, a modern and attractive option. This material goes well in buildings with wooden and brick frames.

For a building that consists entirely of bicarbonate panels, you do not need a foundation. The earth can simply be compacted and covered with paving slabs.

The structure is created using aluminum profiles, it is necessary to provide for the possibility of ventilation and water drainage. Polycarbonate panels and frames of various types can be tailored to specific needs for lighting and thermal insulation.

Before you attach a veranda to the house, you need to decide on the functions that it will perform. In addition to the necessary drainage and ventilation systems in any case, proper connection to the permanent structure and roof structure, the schedule for using this part of the house is important.

Design and construction summer verandas differs from the requirements for premises with year-round operation. It is also important to note that any extension will require the same care and updating as capital buildings.

Photo of the veranda attached to the house

Planning a future extension to a house requires fairly thorough preparation and at least an approximate calculation of the parameters of the foundation, walls, and roof. It will be necessary to resolve issues of material selection and, of course, you need to understand the issue of how to legalize an extension to the house. Without legal registration of a new house-building plan, the extension will be considered an unauthorized construction and, according to all laws, is subject to demolition.

Where to start planning an extension

Any option for an extension to a house is based on four main documents, on which the future fate of the building will depend:

• Permits for the construction of a building;
• A project for a new building with detailed details of the implementation of the most important components, for example, a diagram of the connection to the main building or the construction of the foundation;
• A diagram of the location of the extension on the site plan, with marked distances between individual buildings;
• Construction estimate.

Often, the construction of an extension to a house is just a small cosmetic expansion of an existing veranda, porch or open terrace. Both elements already appear in the original design of a private house, so its owners believe that nothing needs to be changed in the documents. The external dimensions of a house with an attached room do not change, the distances between objects according to sanitary and fire safety standards remain the same, so there is no point in fiddling with bureaucratic procedures for re-registration of a capital structure.

This logic can still be understood if we're talking about about a country panel house, wooden dacha or any other structure erected without a foundation or falling under the definition of temporary. If we are talking about the construction of capital-type structures, the arrangement of an extension always entails certain consequences.

For your information! Refusal to register, other than a fine or forced dismantling of a building, is primarily an investment “in the air” with the risk of losing everything.

A professionally designed and built extension to the house, photo, can increase the capitalization of the property from 30 to 60%. The situation is quite common for modern brick buildings erected on the slope of a hill or mountain. Instead of a veranda, an extension is being built on stilts brick house, which allows you to increase living space by 40-50%.

Properly executed documents will allow, for example, to increase the amount of collateral in the bank or simply sell the building at its real price. Whereas an illegal extension to the house will only create problems.

Registration of an extension, let's look into the details

In order to correctly assess the possible amount of bureaucratic red tape, it is necessary to draw up the following description in as much detail as possible:

• Decide on the purpose of the future building, its size and location relative to the house;
• Make sketches, you can even draw them by hand, but with mandatory compliance generally accepted rules paperwork, it is best to use ready-made projects for extensions to the house;
• Include in a separate document the details for the construction of the foundation or base, walls and roof of the extension.

All of the above will be required in order to correctly classify buildings. Any options for an extension to the house, photos are classified either as permanent buildings or non-permanent buildings.

The paperwork scheme depends on how the city inventory bureau employees classify the building.

Papers for non-permanent buildings

The question of correct classification is not as obvious as it might seem at first glance. Non-permanent extensions include:

• Stairs and porches at the new entrance to the house;
• Canopies, terraces, verandas, balconies;
• Auxiliary and temporary extensions, if they do not affect communications or supporting structures of a permanent structure.

Some experts and some lawyers define a non-permanent extension as a structure without a foundation, but it would be wrong to be guided by such a rule in all situations since there are a huge number of by-laws and clarifications to the norms of the Town Planning Code, plus numerous court decisions that contain provisions that contradict each other. Therefore, before legalizing an extension to a private house, it will be useful to get acquainted with at least some of the regulatory documents.

To design such an extension to the house, do the following:

• Order a drawing for the extension and make a technically competent description of the structure;
• Write an application to the Bureau of Technical Inventory to make changes to the passport of a capital building, that is, a house with an extension;
• Wait for the inspection of the erected structure of the extension to the house;
• Document changes to the house design.

As a rule, there are no problems with registering a non-permanent extension to a house, but even if an official refusal is received, registration can be done by court decision.

Design of a permanent extension

Most brick, stone or metal frame extensions are considered permanent by law. One of the arguments used by experts to justify their decision is the presence of a foundation in any form. Therefore, when planning a full-fledged extension to the house, owners show miracles of ingenuity, which is what it costs to erect a building with a cantilever or balcony type fastenings to the walls of the main house.

According to the law, a major extension will require a building permit from the regional department of architecture and capital construction.

Documents to be submitted:

• Application with a photocopy of the passport;
• Registration certificate for the house and attached site plan;
• Project for a future extension with a short explanatory note.

Upon a positive decision, the owner is issued a written permit to erect the structure, subject to the design and registration of the structure in the state register.

After the extension to the house is completed, you will need to go through all the bureaucratic procedures at the BTI, where they may be forced to do an additional examination to determine the compliance of individual components with SNiP and GOST standards. After entering the technical documentation for the house, the changes are registered in the state register of capital construction and real estate.

Of course, you can build a building without all this bureaucracy, but as practice shows, it is still cheaper to register the attached premises.

How to plan a house extension

The second headache of any process of building an extension is the inadequacy of the frame of the main house building. Only in 1 out of 100 cases, when drawing up a house project, does the future owner have the wisdom to foresee the possibility of expanding the main structure of the building through one or two extensions. The most common problems are imperfect foundation systems or complaints from neighbors.

What to do with the foundation

The simplest situation is when a full two-meter strip foundation is laid under the main building. In this case, you can use a shallow type for an attached room without any particular concerns. strip foundation. If the height of the extension is higher than one floor, then the foundation will have to be deepened to the freezing level; the upper reinforced belt will have to be tied to the slab interfloor covering main building.

The most reliable and durable extension to a house is one made on the same foundation as the brick frame of the house. For example, you can use a section of the foundation occupied by an open veranda. To reduce the pressure on the corner sector of the foundation, the extension box is partially supported on the foundation of the veranda, and most of the weight is transferred to piles driven at a distance of at least 60 cm from the blind area line.

If the house stands on a shallow or pile foundation, then the simplest solution to the problem would be to use slab foundation. The foundation slab for the building is poured over an area 2 times larger than the dimensions of the building itself. At first glance it looks wasteful, but in fact it is just a way to reduce the impact on the foundation of the house and make a foundation for the future. In all other cases, experts recommend erecting the building on a pile foundation without rigid connection to load-bearing structures Houses.

Wall and roof materials

Three types of materials are most often used to construct an extension box:

• Gas silicate blocks or foam concrete on a strip foundation;
• Wooden or metal frame structures on a pile foundation;
• Hollow ceramic brick on a slab foundation.

In principle, you can build an extension from any material, even from rubble or concrete blocks, but in practice they try to make the attached room as light as possible so as not to break the foundation, so even brick buildings are a rarity today.

Most often, the box is built from foam concrete blocks; they are lightweight, relatively easy to lay walls and cost less than brick. Thanks to its excellent heat and sound insulation characteristics, the building can be made with huge windows or even an entire wall of glass.

The second most popular is the frame system. Using profiled pipe and steel profile allows you to assemble an openwork glass extension on two floors. The weight of such a design will be only slightly greater wooden frame, so a particularly powerful foundation for the building is not required. The only condition for the construction of a metal-frame extension will be the correct placement of the structure relative to the foundation of the house. The best option is internal corner facade, ensuring maximum rigidity of the foundation and stability of the walls.

Traditionally, they prefer to install an attached room to a house on the corner of the main building. This part of the foundation of a brick or block house has the highest rigidity and stability, which in turn has a beneficial effect on the attached box itself.

If the additional room is built from wood concrete or aerated concrete, and the place for the foundation is in the center of the main building, in this case it is necessary to take measures to increase the stability of the attached box by all available means.

As such they may be additional wall made of brick or a rebuilt common roof.

The exception is frame buildings made of timber, as a rule, a box made of boards and timber has sufficient rigidity and relatively light weight, so it can be attached anywhere in the house, without regard to the foundation.

Conclusion

Choosing a plan or project small room it is necessary to take into account possible problems from neighbors. Oddly enough, according to statistics, the largest number of court decisions on the forced demolition of extensions in the private sector are based on complaints and claims against neighboring houses. Therefore, it is not enough to plan the foundation and start construction; it is also necessary to provide the structure permits in case of a possible conflict.

An excellent way to increase space is to add an extension to a wooden house. Projects of such structures amaze with their diversity and scale. After choosing a suitable project, you need to prepare special materials. An additional extension will be useful when creating a kitchen area or a luxurious terrace. You can build any room yourself, but you need to choose the right type of construction.

Extension to a wooden house: designs of structures made from various materials

Some time after construction work, there may be a need to increase the usable area. A wonderful solution could be to create an extension to a wooden house. Projects of various structures can be seen in the photo.

Choosing architectural form designs, do not forget about creating a single ensemble in style. For such a structure, special documentation and permission are required. Before construction work, it is necessary to study technological features and design options.

Worth considering the following options outbuildings:

• TO simple designs refers or dining area. It is used for protection from bad weather and sunlight. Under the canopy you can have picnics and receive guests. A strong foundation is not required for its construction. Pillars are installed as supporting supports, to which the frame and planned wall surfaces are attached.

Such structures are often built from logs, beams, foam blocks, and also bricks. Frame technologies are often used.
