How to Build an Extension to the House?

The house is being expanded to increase the area. The only way to do this is to build an extension. Works are accompanied by building nuances, for example, an extension to a wooden house has some features compared to other building materials. In addition, legal requirements must also be observed.


Features of the home extension

Wall material, identical to the main one is chosen more for external harmony. At the same time, the main thing is that the foundation for the extension to the house should correspond to the basic one. When you build it, it is necessary to observe the rules, ignoring of which leads to subsidence, distortion, destruction of the base.

Before making a decision to expand the area of the house, study the following parameters of the facade:
Type of foundation, its width, depth, height;

Condition of walls and roof; the need to replace certain elements or dismantle the roof;

The possibility of attaching the wall rigidly, making the transition to the main part of the house;

Type of entrance to the additional part (common entrance to the house or through the internal rooms).


Features of the wooden structure is that it shrinks throughout the year. This means that the extension to the wooden house should not be rigidly attached to the wall of the facade. In this case, leave the expansion joint, which is a small space between the house and its new part. The height of the foundation and the depth of its bedding should coincide with the parameters of the base of the house.


How to make an extension?

So, according to the project, a foundation is being built. If the material of the extension is not a tree, but a brick or foam block, then the foundation is connected to the base of the house, because it does not shrink. To do this, use the method of hammering the reinforcement in the old foundation. The new foundation may be less deep, but never deeper. For example, an extension to the house of foam blocks is constructed from the same material with the same lining. Then it is enough to make a shallow-landed strip foundation, as it has a small weight and a smaller area.


After the waterproofing of the upper part of the base, the walls are erected and the floor is lined on logs. If an additional part is being built to the old house, it makes sense to dismantle the roof and put a new one on the whole house, including a new part. In this case, the construction of an extension to the house is complicated by a large volume of roofing work. However, the result will be the unification of the two buildings into one harmonious house. This is especially true if the residential part is being completed. If a separate roofing device is planned, a simple option is a roof with the same roofing material as the main one.


Additional constructions

It is important for external insulation of the new area to calculate the dew point, since it is necessary to make an extension to the house with facing properly. In the cold time it should not move towards the inner half of the wall. Errors will lead to the appearance of condensation, then to dampness and wetting of the surface. It will ruin the microclimate in the extension, and in the whole house, if a doorway or arch is made between them.


The completed part can be heated from the heating system of the house. Then build up pipes, install radiators. Other elements: it can be a veranda connecting the residential part of the house with the street. In this case, a doorway is made in it, if desired, a porch is added to it too.


Variants of structures depend on the purpose of the extension. For example, if it is planned to place a kitchen, a bathroom or a bath, it is equipped with a water supply and sewage system. In general, it follows that if the foundation technology is observed, the area of extension can be any. Also it can be 2-storied, if you want to combine it with a 2-storied house.
