A wooden extension to a wooden house can begin to be erected 2-3 years after the end of the felling of the main building. Such a need may arise in several cases. For example, in case of financial difficulties at the time of the work or when there is a need to increase the originally conceived area of the house.
Preparation before construction
Before starting work, it is recommended to make a drawing of the extension. It is necessary to consider how the docking will be carried out. This is required in order to eliminate the occurrence of gaps. At the same time, it is important to make an extension harmoniously combined with the house. If you decide that you need a warm annex to a wooden house, you will have to get the appropriate document from 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, the service will cost about 25,000 rubles or more, the specific amount will depend on the complexity of the project.
Varieties of extensions
A wooden annex to a wooden house may be based on a frame or be deprived of it. In order to determine which structure will be the basis, it is important to take into account the number of floors, the availability of free space for work, the extension area, as well as the characteristics of the main house. The most common option is the one that assumes the presence of the same material as the walls of the main building at the base of the extension. For example, if a house is built of glued timber on the plot, then the extension should also be built from it, but the exterior finish can be from any material. If you bypass this recommendation, you may encounter the problem of different shrinkage. This will certainly cause cracks in the mates. If there is a desire, then it is possible to make not one, but two floors, the technology allows this. The roof should be pitched one-sided, and the roof should be common.
Construction Guidelines
The wooden extension to the wooden house will have such characteristics that are influenced by the fact whether the owners are going to use it for living.
If yes, then it is necessary to erect a separate base, and after that - a connecting wall, a communication system must be provided here. Under the described conditions, the main building is not rigidly connected with the annex by means of fasteners; in addition, there must also be a deformation seam. It is required for shrinkage processes. Among its features, mobility and the ability to breathe can be distinguished, which eliminates the likelihood of damage to the walls of the extension.
A frame extension to a wooden house is the most common addition option, as a rule, it is made using a beam. After the construction, the extension must be insulated, and its external walls are finished with finishing material similar or identical to that used in the construction of the main building. The construction of the frame involves fixing it to the main walls by means of steel brackets, brackets or plates.
Construction Technology
In order to build a wooden annex to a wooden house, you must first calculate the required amount of material and purchase it, after you have to build the base of the house, walls and roof. The following is the finishing step.
Foundation construction
As a rule, an extension is done in order to extend the residential part of the house. In this case, as mentioned above, the foundation will be separate. The depth of its laying should be identical to the one on which the foundation of the main house is laid. The pairing of the two bases is carried out by the reinforcement method. If this process is not carried out, then over time, the bases can diverge in different directions. Initially, marking is to be done, then you can begin to work with the ground. For this, a pit is prepared in which the formwork is laid, it is recommended to use plywood or wide boards. In order to eliminate the occurrence of problems at this stage, the walls of the pit should be made as even as possible, compacting them.
By erecting a wooden extension to a wooden house, the photo of which is presented in the article, you can proceed to the reinforcement at the next stage. This implies not only free laying of the rods, but also a bunch with the main foundation. Only after that it is possible to prepare a solution and pour it into the formwork.
The stage of construction of the foundation must be accompanied by waterproofing. For this, it is customary to use roofing material laid on the surface of the base after concrete hardening. In order to get a more airtight system and protect the walls from water, you can treat the base with a solution of bitumen. In some cases, there is a need to build not a residential extension, but a light one, in the form of a veranda or terrace, then construction involves the installation of a lightweight variety of the foundation, while piles can be used. Its independent construction will cost quite inexpensively and will save.
Walling
When erecting a wooden extension to a wooden house, the photo of which is presented in the article, the same wall construction technology that was used when cutting the walls of the main house should be used. In this example, a profiled beam is considered. In this case, the insulation is laid in specially prepared grooves. If a solid log is used, then the insulation should be laid so that its ends hang on both sides of the wall. In both cases, one must not forget about the presence of a deformation seam, the presence of which eliminates the rigid connection of the walls. And the resulting space will have to be filled using construction foam.
If a wooden extension to a wooden house with your own hands is made of the same material, then the walls can be mated using special fasteners. To do this, 5 cm dowels should be made in the beam. Screws and plates will allow the connection to be made. For this, steel brackets are also used, which are located on each 2-3 link.
Roof device
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 rainfall at the junction. Additional pairing with the main structure is not required. In order to provide more impressive strength, it is permissible to install bars, the distance between which will be equal to 15 cm.
A wooden extension to a wooden house with your own hands can be built from two floors, in this case, the roof can be connected to the main one. Why do you have to partially dismantle the main roof and pair the floors using steel corners. After this, the waterproofing material and the roof are laid. When equipping the roof of a two-story extension, you should not ignore the requirement to install a drainage system. In this case, there is a need to make the design of the drainage system unified.
Extension cost
In order to calculate how much money it will take to build an extension to a wooden house, several factors should be taken into account. Among them, one can single out the technology of work and the type of construction, the number of floors, the complexity of the foundation, as well as the type of timber. It is also important how complicated the design will be. So, the construction of the base can cost a minimum of 350, a maximum of 750 rubles. Formwork can cost between 70-130 rubles, reinforcement laying - 130-250 rubles. Laying timber - 1000-2500 rubles / m 2 . Laying a lag costs about 1200-2700 rubles. Installation of the roof costs 150-230 rubles / m 2 . The indicated prices do not include the cost of the material. But even if you decide to attach the room to a wooden house, the prices mentioned will not be final, because you still have to pay for the delivery of the material and the subsequent finishing work.
Opportunity to save
In order to significantly save money, it is recommended to purchase timber in the winter. Filling the foundation with your own hands also reduces costs, the savings will be approximately 20% of the final cost. In addition, you can purchase material that has already been in use. The frame extension will also be cheaper, but in order to match the house, you can finish from a material that simulates a beam. Thus, you can just attach the garage to a wooden house, the frame structure is perfect for him.
In general, of course, independent construction will cost much less. For this, it will only be necessary to purchase material and spend your personal time. And if you built the main building yourself, then it will not be difficult for you.
