In order to make the house comfortable,the optimal solution is to create an additional area. 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 is easier to make changes to them than to rework the already finished construction.
Objectives of building an extension
- Arrangement of a summer veranda or porch.
- Creation of a technical room (workshop, garage, boiler room, electrical room, pantry).
- Expansion of 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 differenceadditional premises, there is a mandatory 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, cant timber and even aerated concrete blocks are suitable for it. But the wooden extensions remain preferable.
The most rational option isattaching the frame structure. The presence in the sale of modern materials makes it possible to make the new premises as comfortable and functional as possible throughout the year.
What should be considered when creating an extension?
The construction should include the following factors:
- View of the foundation and its dimensions.
- The condition of the walls with the roof and what elements require replacement.
- The ability to rigidly connect structures and create a transition between rooms.
- Transitions between rooms.
Due to the fact that the wooden extension givesshrinkage during the first year after construction, its rigid attachment to the walls of the house is not recommended. Between them leave the so-called deformation seam, providing relative slippage of the walls vertically. 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, polystyrene foam, plastic mass of bitumen, silicone or acrylic.
When combining different materials in placeconnections are used embedded elements: fittings, channel, corner. The tightness of the joint is created with a gap of 1-2 cm, which is subsequently filled with mounting foam and closed with a splat. Metal should be carefully painted to protect against corrosion.
It is quite possible to create a basement under the newby the room. In this case, a strip foundation is required. But to lay a new foundation below the sole of the old can not. The sole of the extension base must be the same as that of the house, or placed higher.
The most popular projects are extensions tothe wooden house thanks to profitability, simplicity and efficiency. First of all, the project is created. The extension complements the house, creating a whole, and not a separate part of it. It is important to consider the state of the walls in contact and, if necessary, replace the rotted parts.
Should adhere to one style.The dimensions of the additional building should not exceed 2/3 of the house. It should be borne in mind that the overall appearance of the facade is not disturbed. The area of the veranda is usually about 20% of the house.
The extension may be a two-story.It is important to ensure its reliable thermal insulation. If the adjoining room is combined with the rooms of the house with doorways, it should be reliably insulated. Otherwise, it will affect the microclimate of the whole house. Protection against cold should be provided on all sides.
When changing a dwelling house permission is requiredCity Architectural Committee. Prepare all the necessary drawings. The price of the services of a construction company, which is taken to create a project of an extension to a private house, is from 25,000 p. You can select the appropriate option for the proposed photo.
Typical ready-made projects are difficult to apply.as necessary to bind to the existing structure of the house and the condition of the soil. 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.
Building a new foundation
When projects are designed extensions towooden house, special attention is paid to the foundation. So that it does not shrink, it is connected to the base of the house. Monolith can not be obtained, but you can get closer to this. At first the trench is dug and the attached parts of the main foundation are released. The waterproofing is removed from it, and then the cuts to a depth of 60-80 mm are drilled out with a crown with a diameter of at least 100 mm. Then, instead of a crown, a drill is inserted and thin holes are drilled in the concrete. Then the reinforcement is hammered into them. The framework of the new foundation is tied to it and it is poured with concrete. After hardening, waterproofing is laid on the base, after which you can 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, over time they can disperse.
How to make a roof?
The roof of the annexe is built separately.It makes a shed and with a big slope. Connection with the main building is not made. At the same time 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 shrinking and shrinkage of the structure.
The roof is located below the main or done withher as one. It should be envisaged that the shrinkage of the new structure does not lead to the subsidence of the roof. If the decision is made to build a common roof, then it will be necessary to reconstruct the entire roof.
Construction of an extension from a bar
Projects extensions to the wooden house most oftenprovide for the manufacture of new designs 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 there are around the house. Then the foundation is made the same, and the roof can be common or one-sided pitched. Under the veranda used lightweight column base.
The walls are built using the same technology as for the main house. The beam connects among themselves dowels. Fastening to the main wall is made with plates with screws or brackets.
The extension of the bar is usually designed for residential premises.
For her, the roof can be made common by connecting the overlap with metal corners. The design of the drain system is made whole.
Expenses for an extension are added as follows:
- type of construction and decoration;
- number of floors;
- basement complexity;
- availability of communications;
- type of timber.
The general list also includes the project price, transportation and construction complexity.
The frame base is the simplest andcommon solution for the construction of an extension to a wooden house. Despite the fact that this technology has appeared recently, it has received universal recognition due to its economy and speed of construction.
The frame is made of wood or metal.The cost of construction depends primarily on its purpose. The highest costs are required for the construction of residential premises where insulation of mineral wool, foam plastic, polyurethane foam and other heat-shielding materials is required.
Metal structures are made of profiles of different shapes and sizes by welding. Cheaper wooden frame is also durable and durable.
The foundation is small and may be shallow or columnar. It is displayed on a par with the main one on the upper level.
The wooden frame is treated with antiseptic andfire-fighting composition. Then it is assembled. On the side of the facade, the walls are sheathed with sheets of plywood or OSB, trimmed with siding or plastic, and from the inside with clapboard. If it is precoated with several layers of lacquer, the service life of the material will last significantly. Between the outer and inner lining fit insulation.
The extension of the porch to the frame structure is not difficult. Under it is a small foundation associated with the main.
The extension to the house allows with minimalcosts increase living space and create a comfortable living environment. This can be done with your own hands, if you competently develop your own or make changes to ready-made projects with reference to specific conditions. At the same time it is impossible to make mistakes in construction.
