Wooden annex to the wooden house with their own hands (photo)

A wooden annex to a wooden house can be started to be erected 2-3 years after the completion of the main building. This need may arise in several cases. For example, with financial difficulties at the time of work or when there is a need to increase the originally conceived area of the house.

Preparation before construction starts

Before starting work, it is recommended to draw an extension drawing. It is necessary to consider how docking will be carried out. This is required in order to prevent the occurrence of slots. It is important to make an extension that is in harmony with the house. If you decide that a warm add-on to a wooden house you need, you will have to get the appropriate document in the architectural committee. You can create a project yourself, but for this it is important to have the appropriate skills, if you turn to professionals for this, then the service will cost about 25,000 rubles or more, the specific amount will depend on the complexity of the project.

Variation of extensions

A wooden annex to a wooden house can have a frame or be deprived of it. In order to determine which design will be based, it is important to take into account the number of floors, the availability of space for work, the area of the extension, as well as the characteristics of the main house. As the most common option is the one that suggests the addition of the same material from which the walls of the main building consist. For example, if a house is built on a plot of glued timber, then the annex should also be erected from it, but the exterior finish can be made of any material. If you circumvent this recommendation, you can face the problem of different shrinkage. This will certainly cause slots in the mates. If there is a desire, it is possible to make not one but two floors, the technology allows it. The roof must be sloped one-sided, and the roof-common.

Recommendations for construction

The wooden annex to the wooden house will have such characteristics, which are affected by the fact that the owners are going to use it for living.

If so, it is necessary to erect a separate basis, and after - a connecting wall, there must necessarily be a communication system. Under the conditions described, the main building is not rigidly connected with the annexe by means of fasteners, in addition, there must also be a deformation seam. It is required for shrinkage processes. Among its features can be identified mobility and the ability to breathe, which excludes the possibility of damage to the walls of the extension.

Frame attached to a wooden house - this is the most common option of the supplement, as a rule, it is made using a bar. After construction, the extension must be insulated, and its external walls are finished with a finish material, similar or identical to that used in the construction of the main building. The erection of the frame implies fastening it to the main walls by means of steel brackets, brackets or plates.

Construction technology

In order to build a wooden extension to a wooden house, you must initially calculate the right amount of material and purchase it, then you have to build the base of the house, the walls and the roof. Then follows the finishing step.

Foundation construction

Typically, an extension is made in order to extend the residential part of the house. In this case, as was said above, the foundation will be separate. The depth of its laying should be identical to that on which the foundation of the main house is laid. The conjugation of the two bases is made by the reinforcement method. If this process is not carried out, then over time, the grounds may disperse in different directions. Initially, it is necessary to make a markup, then you can start working with the land. For this purpose a foundation pit is prepared, in which the formwork is laid, it is recommended to use plywood or wide boards. In order to avoid the occurrence of problems at this stage, the walls of the excavation should be made as even as possible, compacting them.

Raising a wooden extension to a wooden house, the photo of which is presented in the article, you can move to the next stage to reinforce. This implies not only the free laying of the rods, but also a bundle with the main foundation. Only after that you can prepare the solution and fill it in the formwork.

The stage of erection of the foundation must necessarily be accompanied by waterproofing works. For this, it is customary to use a roofing material laid on the surface of the base after the concrete has hardened. In order to obtain a more hermetic system and protect the walls from the effects of water, it is possible to treat the base with a bitumen solution. In some cases, there is a need to build a non-residential annexe, and a light one, in the form of a veranda or terrace, then construction involves the installation of a lightweight variety of foundation, and you can use piles. Its independent construction will cost quite inexpensively and will save you money.

Walling

While erecting a wooden extension to the wooden house, the photo of which is presented in the article, one should use the same technology of wall construction, which was used in the felling of the walls of the main house. In this example, a profiled bar is considered. In this case, the insulation is laid in specially prepared grooves. If a solid log is used, the insulation must be laid in such a way that its ends hang on either side of the wall. In both cases, one should not forget about the presence of a deformation seam, the presence of which excludes the rigid joining of the walls. And the received space should be filled, applying a building foam.

If a wooden annexe to a wooden house with its own hands is made of the same material, the mating of the walls can be carried out using a special fastener. To do this, you need to make a 5 cm dowel in the bar. The screws and the plates will make the connection possible. For this, steel braces are also used, which are located on each 2-3 links.

The device of a roof

If the extension is supposed to be built much lower than the main wooden house, then the roof should have a significant slope, which will prevent the accumulation of precipitation at the junction. Additional interface with the main structure is not required. In order to provide a more impressive strength, it is permissible to set the beams, the distance between which will be 15 cm.

A wooden annexe to a wooden house with its own hands can be built and from two floors, in this case the roof can be connected to the main one. For this, it will be necessary to partially dismantle the main roof and make the overlapping of the floors, using steel angles. After that, the waterproofing material and the roof are laid. By equipping the roof of a two-storey extension, one should not bypass the requirement to mount a drainage system. At the same time, there is a need to make the design of the drainage system uniform.

Cost of annexe

In order to calculate how much money will be spent to build an annex to a wooden house, several factors should be taken into account. Among them, we can distinguish the technology of work and the type of construction, the number of floors, the complexity of the base, and a variety of timber. It is also important how complex the design will be. So, the construction of the base can cost a minimum of 350, as much as 750 rubles. The formwork can cost between 70-130 rubles, the laying of the reinforcement - 130-250 rubles. Laying of timber - 1000-2500 rubles / m ² . Laying the log costs about 1200-2700 rubles. Installation of the roof costs 150-230 rubles / m ² . The prices indicated do not include the cost of the material. But even if you decide to attach a room to a wooden house, the prices mentioned will not be final, because you will still have to pay for the delivery of the material and subsequent finishing work.

Possibility to save money

In order to save money, it is recommended to purchase the beams in the winter. Pouring the foundation with your own hands also reduces costs, saving will be approximately 20% of the final cost. In addition, you can purchase material that has already been in use. The frame attachment also turns out to be cheaper, and in order for it to match the house, it is possible to finish the material that mimics the bar. So just you can attach a garage to the wooden house, the frame construction for it is perfect.

In general, of course, independent construction will be much cheaper. To do this, you will only need to purchase material and spend your personal time. And if the main building you built yourself, then for you it will not be difficult.
