Circumstances in life can change in a variety of ways and may need to increase the space of your home. One of the significant advantages of private construction is that it is easy to do more. Before expanding, it is important to become familiar with how to properly build an extension to the house, even if workers will be engaged in its construction.

Various extensions to houses

Structures of buildings from various materials

An extension can have many variations of forms, design and technical capabilities. Not only the construction material can differ. Each frame extension to a wooden house requires following certain rules and has its own characteristics. A certain type of project may have its pros and cons. That is why it is important to weigh everything carefully and decide which type of project is best suited.

In construction material plays a key role. The functionality and cost of the building depends on which raw materials will be selected for construction. For example, in the construction of a wooden frame, you can live in summer and in winter. If the wall material to a greater extent consists of glass, then this type is reassigned only for the warm season. So, there are several types of materials:

  • foam blocks,
  • timber,
  • brickwork,
  • frame assembly.

Project of a wooden extension from timber

The shape and purpose of the extension

The buildings differ not only in the material chosen for construction, but also in the shape of the structure. Such facilities are divided into the following types:

  1. Additional room.
  2. Veranda with open or closed type.
  3. Enlarged porch with a visor.

Additional room

This project involves the construction of another additional room in which you can live all year round. Typically, such projects are made from raw materials that retain heat well and do not let the cold through well. Wood serves as an excellent heat insulator, and all rooms are made mainly of wooden beams. You can use foam blocks or bricks, but in this case it is important to warm up well. This type of project has a number of positive and negative qualities.

Additional room in the annex


  1. You can significantly extend the useful area of ​​the house.
  2. Unlike a separate building, it is easy to conduct light and heating.
  3. In this case, the construction of an extension to the wooden house will perfectly complement the existing interior and exterior, without violating its integrity.
  4. Even after the end of the construction cycle, a room can be easily converted for any needs (bathroom, pantry, kitchen or living room).


  1. A good insulation and a strong foundation is required, which guarantees an increase in the total price of the building.
  2. The implementation of this project requires a lot of free space. This is a significant drawback for those who have a small area.

Closed veranda

The project in the form of an attached veranda has two main varieties. The extension to the house of brick and lumber fenced with four walls that protect from the effects of external factors. Verandas of the closed type are rarely heated, they are often used seasonally. The traditional finishing material is glass. Such an extension fits perfectly in almost any design. Veranda closed, will be a great place to relax in any weather.

Open veranda

The frame extension attracts with its simplicity and functionality. Often such projects are made of wood. Similar verandahs are used in tandem with wooden houses of the same material. This option is much easier to implement than the gazebo. Moreover, such extensions generally do not take up much space and require a minimum amount of raw materials. Such projects have gained great popularity due to its practicality and the mass of positive aspects.

They are equipped with special chairs or chairs and can be used as a small gazebo.

Construction of the frame extension to the house

Any construction requires careful planning. An extension to a brick house is hard work that does not do without experience and skill. The same can be said about the implementation of a specific project for wooden structures. No matter what type was chosen, the principle of construction is one. The whole cycle of the erection of a structure can be divided into several stages:

  1. Construction of the foundation.
  2. Walling.
  3. Installation of the subfloor.
  4. Installation of the roof and ceiling.

Construction of the foundation

The foundation of any building is the foundation, which means it must be made of high-quality materials. In the case of use of unsuitable raw materials with low performance indicators extension to the house from the frame will be damaged. If the foundation begins to collapse, then you may have to disassemble the walls and roof, which threatens serious financial costs. In addition to the acquisition of quality materials, it is necessary to strictly follow the technological process.

Foundation for the extension

Any laying of a new foundation to the old foundation requires precise calculations. Ideally, it is necessary to lay the foundation for two structures at once, but this happens very rarely. For docking use special reinforcement, which allows you to cling to the foundation of the house. When pouring it is important to know and take into account two factors:

  1. The identity of the composition.
  2. Uniform Depth.

Concrete must completely repeat the composition and structure. This will ensure a uniform structure and a stronger connection. Uniform depth allows the foundation to sink at the same level. If this is not taken into account, cracks will go along the foundation, and the structure of the house will be badly damaged.


After the foundation has been formed, you need to proceed to the next stage - the construction of the walls. There is an unspoken rule - to use material that is identical with the main building. So, if an extension to the shield house is performed - you need to use walls made of shields, if the house is brick - to use bricks, etc. But what if there is no similar material? You can use an additional layer of the same lining. Finishing the house completely is a costly matter, but the problem of unification will be solved.

It is important to remember that if an extension to the old wooden house is needed, the projects will have to be chosen in the general style. It is necessary to use the material from which the house is made. The closer the similarity, the more organic the structure will look.

Laying the walls

At the time of planning, you need to understand whether the extension will have its fourth wall? If it is in the project, what is the gap between the two buildings? If the additional room is well heated and it is planned to live in it all year round, then the additional partition is meaningless. In a badly heated room, an airbag will protect the house from the cold.

Installation of a subfloor

A flat floor is the basis of a comfortable life. In order not to suffer later, it is important to make a smooth and even draft for the floor covering. When performing pouring and screed, it is important to use modern equipment such as a laser level. It is important to know that without proper experience in building and expensive equipment it is impossible to do the perfect job. "Curved" rough floor will give a complication in the construction of a warm floor. If you lay the parquet on poor-quality coating, then creaking and sagging is a guaranteed result.

Installation of the subfloor

Installation of the roof and ceiling

As with the walls, the roof of the roof should be a continuation of the main house. Due consideration should be given to beams and ceilings.They must comply with all modern standards and fire safety standards. If the selected project does not imply permanent residence, then you can do without insulation. The same applies to the ceiling. For example, in the veranda or porch you can do without a ceiling. It all depends on the extension plan and the project of the main building.

When planning the construction of additional square meters, it is worth taking into account that this is a complex technological process. If you take up construction with your own hands, the risk of making a mistake is increased. To avoid unnecessary expenses, it is better to seek help from professionals who know their business. Having in their arsenal a sufficient amount of experience and professional expensive equipment, they will perform quality work in the shortest possible time. As a result, the owner is waiting for high-quality work without overpayments, time and extra nerves.
