In order to make the house comfortable, the optimal solution is to create additional space. First of all, extension projects for a wooden house and any other should be correctly legally executed.
This is better to do beforehand, since it is easier to make changes to them than to redo the already finished structure later.
The purpose of the construction of the extension
- Arrangement of a summer porch or porch.
- Creation of a technical room (workshop, garage, boiler room, switchboard, pantry).
- Expansion of the living room (living room, bathroom, kitchen, dining room, hallway).
It should be borne in mind that the extension has some features in comparison with other structures.
Which annexes are suitable for a wooden house?
Despite the functional difference between the additional rooms, there is a prerequisite - ensuring the safety of the main building. For wooden houses, the use of extensions of the same material is advisable in order to create harmony and prevent overloading the foundation. If the main building is a log house, logs, timber and even aerated concrete blocks are suitable for it. But wooden outbuildings remain preferred.
The most rational option is to attach the frame structure. The availability of modern materials on sale makes it possible to make new rooms as comfortable and functional as possible year-round.
What to consider when creating an extension?
The following factors should be provided for in construction:
- Type of foundation and its dimensions.
- The condition of the walls with a 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 shrinks during the first year after construction, it is not recommended to rigidly fix it to the walls of the house. Between them leave the so-called deformation seam, providing relative sliding of the walls vertically. It is necessary even with a common foundation and separates all parts of the building from the bottom up, down to the roof. Finally, the seam is filled with elastic bands, polystyrene foam, a plastic mass of bitumen, silicone or acrylic.
When combining different materials at the junction, embedded elements are used: fittings, channel, corner. The tightness of the joint is created using a gap of 1-2 cm, which is then filled with polyurethane foam and closed with a stripper. The metal should be carefully painted to protect against corrosion.
It is quite possible to create a basement under a new room. In this case, a deep foundation tape foundation is needed. But to lay a new foundation below the sole of the old is impossible. The sole of the foundation of the extension should be the same as the house, or placed higher.
Project work
The most popular were the extension projects to the wooden house due to its cost-effectiveness, simplicity and efficiency. First of all, a project is created. The extension complements the house, creating a single whole, and is not a separate part of it. It is important to consider the condition of the walls in contact and, if necessary, replace the rotten parts.
One style should be followed. Dimensions of the additional structure should not exceed 2/3 of the house. In this case, it is necessary to take into account that the general appearance of the facade is not disturbed. The area of the veranda is usually about 20% of the house.
The extension can be two-story. It is important to ensure its reliable thermal insulation. If the annexed room is combined with the rooms of the house with doorways, it must be reliably insulated. Otherwise, it will affect the microclimate of the whole house. Protection from the cold must be provided on all sides.
When changing a residential building, permission from the city architectural committee is required. All necessary drawings are prepared. The price of the services of a construction company, which is taken to create an extension project to a private house, is from 25,000 p. A suitable option can be selected by the proposed photo.
It is difficult to apply typical finished projects, since it is necessary to bind to the existing construction 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.
The construction of a new foundation
When projects are being developed for an extension to a wooden house, special attention is paid to the foundation. So that he does not shrink, he is connected to the base of the house. You won’t be able to get a monolith, but you can get closer to this. First, a trench is rummaged and the attached parts of the main foundation are freed. Waterproofing is removed from it, and then, with a crown with a diameter of at least 100 mm, recesses are drilled to a depth of 60-80 mm. Then, instead of the crown, a drill is inserted and thin holes are drilled in concrete. Then the fittings are clogged in them. The frame of the new foundation is tied to it and it is poured with concrete. After hardening, waterproofing is laid on the base, after which it is possible to build an extension of any material, but it is not recommended to create heavy structures.
If the reinforcement of the two foundations is not done, they may diverge over time.
How to make a roof?
The roof of the extension is being built apart. It is made single-handed and with a large bias. Connection to the main structure is not performed. 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 one or is made with it as a whole. It should be provided that the shrinkage of the new structure does not lead to subsidence of the roof. If you decide to build a common roof, then you will have to do a reconstruction of the entire roof.
The construction of an extension of the beam
Projects of extensions to a wooden house most often involve the manufacture of new structures from the same material, for example, from timber. The building is usually attached to the wall of the facade and can have as many floors as there are at home. Then the foundation is made the same, and the roof can be general or one-sided pitched. A lightweight columnar base is used under the veranda.
The walls are erected using the same technology as for the main house. The beam is interconnected with dowels. Fastening to the main wall is done with plates with screws or brackets.
An extension of the beam is usually intended for residential premises.
For it, the roof can be made common by connecting the floors with metal corners. The design of the drainage system is made integral.
Extension costs add up as follows:
- type of construction and decoration;
- number of floors;
- foundation complexity;
- availability of communications;
- type of timber.
The general list also includes the price of the project, transportation and construction complexity.
Frame extension
The frame base is the simplest and most common solution for the construction of an extension to a wooden house. Despite the fact that this technology has appeared recently, it has been universally recognized because of the cost-effectiveness and speed of construction.
The frame is made of wood or metal. The cost of construction depends, first of all, on its purpose. The biggest cost is the construction of a living room where insulation with mineral wool, polystyrene foam, polyurethane foam and other heat-shielding materials is required.
Metal structures are made of profiles of various shapes and sizes by welding. The cheaper wood frame is also strong and durable.
The foundation is made small and may be shallow or columnar. It is displayed along with the main one at 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, the walls are sheathed with sheets of plywood or OSB, decorated with siding or plastic, and from the inside - lining. If it is pre-coated with several layers of varnish, the service life of the material will significantly extend. Between the outer and inner skin insulation is laid.
The extension of the porch to the frame structure is not difficult. A small foundation is made under it, connected with the main one.
Conclusion
The extension to the house allows you to increase living space and create comfortable living conditions at minimal cost. You can do it yourself if you competently develop your own or make changes to finished projects with reference to specific conditions. At the same time, mistakes in construction should not be allowed.
