Projects extensions to the wooden house. Wooden, brick, frame additions

In order to make the house comfortable, the best solution is to create an additional space. First of all, the projects of extensions to the wooden house and any other must be properly legally formalized.

It is better to do this in advance, because it's easier to make changes to them than to rework the already finished construction.

Objectives of building an extension

1. Arrangement of a summer veranda or porch.
2. Creation of a technical room (workshop, garage, boiler room, electrical room, pantry).
3. Expansion of the living space (living room, bathroom, kitchen, dining room, hallway).

In this case, it is necessary to take into account that the annex has some peculiarities in comparison with other structures.

Which extensions are suitable for a wooden house?

Despite the functional difference of the additional premises, there is an obligatory condition - ensuring the safety of the main building. For wooden houses, the use of extensions of identical material is expedient for the sake of creating harmony and preventing overloading of the foundation. If the main building is a log house, logs, timber and even aerated concrete blocks are suitable for it. But the wooden extensions remain preferable.

The most rational option is to attach the frame structure. Availability of modern materials for sale makes it possible to make new premises as comfortable and functional as possible all year round.

What should I consider when creating an extension?

In construction, the following factors should be provided:

1. Type of foundation and its dimensions.
2. The condition of the walls with the roof and what elements require replacement.
3. The possibility of a rigid connection of structures and the creation of a transition between rooms.
4. Transitions between rooms.

Due to the fact that the wooden extension shrinks during the first year after construction, its rigid attachment to the walls of the house is not recommended. Between them, the so-called deformation seam is left , providing relative slippage of the walls along the vertical. It is necessary even with a common foundation and divides all parts of the building from the bottom up, up to the roof. Finally, the seam is filled with elastic bands, expanded polystyrene, plastic mass from bitumen, silicone or acrylic.

When combining different materials at the connection point, the embedded elements are used: reinforcement, channel, corner. The tightness of the joint is created by means of a gap of 1-2 cm, which is then filled with mounting foam and covered with a latch. Metal should be carefully painted to protect against corrosion.

It is quite possible to create a basement under a new premise. In this case, a ribbon foundation is needed for deep deposition. But it is impossible to lay a new foundation below the base of the old one. The sole of the basement of the extension must be the same as that of the house, or placed above.

Project work

The most popular projects are additions to the wooden house due to economy, simplicity and efficiency. First of all, a project is being created. The extension complements the house, creating a single whole, and not a separate part of it. It is important to consider the condition of the adjacent walls and, if necessary, replace the decayed parts.

You should stick to one style. Dimensions of the additional structure should not exceed 2/3 of the house. It must be taken into account that the general appearance of the facade is not disturbed. The area of the veranda is usually about 20% of the house.

Extension can be two-storey. It is important to ensure its reliable thermal insulation. If the attached room is combined with the rooms of the house by doorways, it must be reliably insulated. Otherwise it will affect the microclimate of the whole house. Protection from cold should be provided from all sides.

When you change a house, you need permission from the city's architectural committee. All necessary drawings are prepared. The price of the services of a construction company that undertakes to create a project of an extension to a private house is from 25,000 rubles. A suitable option can be selected according to the proposed photos.

Typical ready-made projects are difficult to apply, because it is necessary to link to the existing design of the house and the state of the ground. They are taken as a basis, making changes of different levels of complexity, depending on the wishes of customers. As a result, an original solution can be obtained.

The erection of a new foundation

When projects are being developed extensions to the wooden house, special attention is paid to the foundation. To prevent it from shrinking, it is connected to the base of the house. The monolith can not be obtained, but you can approach it. First a trench is digging and the attached parts of the main foundation are released. From it, the waterproofing is scraped off, and then the notch with a diameter of at least 100 mm is drilled to a depth of 60-80 mm. After the crown instead of the crown, thin holes are drilled in the concrete. Then the reinforcement is clogged in them. The frame of a new foundation is attached to it and its concrete casting is performed. After hardening, waterproofing is laid on the base, after which it is possible to build an extension from any material, but it is not recommended to create heavy structures.

If the reinforcement of the two foundations is not done, they may disperse over time.

How to make a roof?

The roof of the extension is erected in isolation. It is made of a single-pitched and with a big bias. Connection with the main structure is not carried out. In this case, it is necessary to ensure a tight fit of the roof to the wall of the house. Then its subsidence will not occur in the process of shrinkage and shrinkage of the structure.

The roof is located below the main roof or is made with it as one unit. It should be provided that the shrinkage of the new structure does not lead to subsidence of the roof. If the decision is made to build a roof common, then it is necessary to do a reconstruction of the entire roof.

Construction of an extension of the timber

Projects of extensions to a wooden house often involve the manufacture of new structures from the same material, for example, from a bar. The building is usually attached to the wall of the facade and can have as many floors as their houses. Then the foundation is made the same, and the roof can be common or one-sided pitched. Under the veranda, a lightweight columnar base is used.

The walls are built using the same technology as for the main house. The beam joins together nagels. Fastening to the main wall is made by plates with screws or staples.

An extension of the beam is usually intended for living quarters.

For her, the roof can be made common, by linking the overlap with metal corners. The design of the drainage system is done in one piece.

Expenses for the extension are as follows:

• Type of construction and finishes;
• number of floors;
• Complexity of the foundation;
• Availability of communications;
• View of the timber.

The overall list also includes the project cost, transportation and complexity of construction.

Frame Attachment

The frame base is the simplest and most common solution for erecting an extension to a wooden house. Despite the fact that this technology has appeared recently, it has received universal recognition because of the economy and speed of construction.

The frame is made of wood or metal. The cost of construction depends, first of all, on its purpose. The most expensive costs require the erection of a dwelling, where warmth is required with mineral wool, foam, polyurethane foam and other heat-shielding materials.

Metal structures are made of profiles of different shapes and sizes by welding. The cheaper wooden frame also features durability and strength.

The foundation is made small and can be shallow or columnar. It is displayed on a par with the main on the upper level.

The wooden frame is treated with an antiseptic and fire-fighting compound. Then it is assembled. From the side of the facade walls are covered with sheets of plywood or OSB, with a siding or plastic finish, and inside - with a lining. If it is pre-coated with several layers of varnish, the service life of the material will be considerably prolonged. Between the outer and inner lining is laid insulation.

The addition of the porch to the frame structure is not difficult. Under it is a small foundation, connected with the main one.

Conclusion

Attachment to the house allows you to increase living space with minimal expenses and create comfortable living conditions. This can be done by oneself, if we correctly develop our own or make changes to the finished projects with reference to specific conditions. In this case, you should not make mistakes in construction.
