It can significantly change the design of the facade. In addition, this method allows you to significantly increase the useful living space with a minimum cost of money and labor. Traditionally it is believed that the additional structure should be created from a material similar to the main building. However, if there is a huge choice of building materials, you can make a general finish or pick up a successful imitation. Materials for walls can be brick, wood, foam concrete, etc. The most profitable is the frame structure.

Types of additional premises
- Room. New residential premises require a special approach, since in fact it is the completion of a house. The room is carefully insulated from all sides and is provided with reliable waterproofing.
- Kitchen. The room has the same quality requirements as for the room, but in addition communications must be provided: water supply and sewerage.
- Veranda. The room is mostly intended forsummer holidays, and also protects the main building from rain and wind. It can be closed, with or without thermal insulation. Also an open version is used, where only the floor with the racks and the roof on the extension to the house remain. In this case, there are options for such designs are not the cheapest.
The erection of the basement for the annexe
The foundation is made columnar or ribbon. It depends on the preferences of the owners and the nature of the soil.
1. Tape foundation
The basis is made in the following cases:
- under the construction of a considerable mass;
- The house has a basement, a ground floor or an underground garage;
- heterogeneous soil.
The foundation can be below the freezing depthsoil at 200-300 mm or shallow depth (depth - 550-600 mm). For light extensions, the latter option is used as the most rational in terms of costs and technical characteristics.
Important!! The attached foundation must be in places with thethe foundation of the house is to make one with it. A single monolith can not be made, but you can connect them with each other if you slam the metal rods in the old foundation and tie them with the reinforcement skeleton. After it is poured concrete.
note!! Tape foundation must be poured in one step, and for this it is better to turn to professionals with the appropriate technique. Preliminary work can be done by yourself.
2. Column foundation
Columns are erected from concrete, bricks or theircombination. Here it should be borne in mind that the underground will be open or unheated, although the problem is solved by installing a vial with additional insulation during the laying of communications.
The posts are placed in 1.5 m increments, with mandatoryinstallation on the corners. Their depth of immersion is 500-600 mm. Underground part is smeared with bitumen for waterproofing. The bars adjoining the main foundation are expediently connected with it by means of reinforcing bars hammered into concrete.
Judging by the reviews and numerous articles, an extension to the house under the roof in most cases is made as a skeleton, since it is the cheapest, and it is quite easy to build it yourself.
The above-ground part of the basement of the house and the annexe are trying to be located at the same height, but for the veranda it can be made lower by connecting the passage with steps or a small staircase.
For any type of foundation, a wooden floor is suitable. For tape it can be made of concrete.
The foundation is stacked aroundperimeter of beams with a height of 150 mm and a width of 100 mm. You can use logs that are cheaper. At the corners they are connected by locks. Before this, a waterproofing from several layers of ruberoid is laid.
For the floor and under the spikes of racks in beamsare made through a 50 cm groove. They put up the racks and fasten the nails. In the places for windows horizontally fasten the beams on which the window board will be installed.
Racks make the height of the room. If the roof is odnoschatnaya, the wall of the house they set a higher height to create an inclination. To ensure that they are located exactly vertically, they are temporarily nailed to them.
From above perform the strapping, in it grooves are maderafters, which are fastened with nails or nails to a horizontal bar. The other side they rely on a wooden bar cross-section 100h89 mm, fixed on the wall of the house with anchor bolts. Rafters are supposed to be fastened to the mauerlat, which is installed on top of the strap. For small buildings, you can do without it.
The roof of the extension must go under the roof of the main house.
The rafters are stuffed with a crate. It can be with lumens or solid, depending on the applied roofing material.
In the grooves of the bar of the lower strapping, lagswith a step of not more than 1 m. The quality of the floor depends on how they are fixed. Each lag is set by level. If the verandah is open, a slight deviation from the house is made, so that the rainwater drains outward.
The floorboards are attached to the lags by screws.
The walls are built in two layers, with an arrangementbetween them waterproofing and insulation. Outside use OSB, plywood, boards, and then trim with siding. Interior decoration is done by sheets of plasterboard or lining.
Attaching the roof to the roof of the house can be done in this way:
- under a common roof;
- annex with a broken roof.
1. Single roof
The most economical option is a one-stageroof extension to the house with a longitudinal adjoining it. Reviews speak in favor of this design, with the exception of design. You can find another, more effective option, if the means allow. The roof is located on the lags of the upper strapping. If you decide not to touch the old roof, which is in good condition, one new ramp is made.
Rigid connection of buildings with each other is notis done. Attachment is fixed by creating a sliding connection with the longitudinal groove, which provides a strong connection of the walls with the possibility of shrinkage. The problem is often the precipitation in the place of the joint of the roof with the wall. To drain the water, a corner or a groove made of galvanized sheet is arranged. With sufficient slope, moisture will not enter.
The single-pitched roof of the extension to the wooden house has distinctive features.
- Tilt angle not less than 100.
- The roof of the extension is put under the roof of the house.
- The extension is subject to the same loads as the house. In addition, its roof is located below the main, and most of the precipitation can fall on it, which makes it necessary to impose strict requirements on the additional structure for strength and waterproofing.
- Externally, the roof of the extension should not look shabby, despite the simplicity of the form.
2. The gable roof
The option is suitable for constructionfull-fledged heated room with an attic. Attachment to the house with a gable roof is more difficult. For its installation, first beams are installed (150x100 mm), which are the basis of the future ceiling. They lie on the upper bandage with a step of not more than 70 cm, and after they are attached to the wall of the house. After the beams a rafter system is installed (bar 100x100 mm).
The distance between them is the same as that of the beams. On the rafters, a crate is punched with a step corresponding to the type of roofing material. The last stage is laying the roof and installing drainage.
3. The broken roof
This method is more expensive, but functionalit is better, because under the roof it is possible to equip an additional room. Due to this, it is possible to save the area of the plot that goes under the housing. Attachment to houses with a broken roof does not always look beautiful. Most often make a continuation of the roof of the main building. In terms of design, you can change its shape here.
Reviews of broken roofs are the most controversial, because sometimes the design is very difficult, and it is difficult to choose the appropriate design.
Broken and gable roof extension to the houseare built on a similar technology. For the dilapidated construction it is advisable to erect a new roof on the house, which will become common for him and the extension. In this case, the structure will increase significantly in size.
For the new roof of the house, the truss system is assembled on the ground in advance. Also, shields for the crate are prepared. As a result, the replacement will be made quickly and efficiently.
Join the roof of the extension and the house
An economical option is to attach the roof to theThe roof of the house, where they connect with each other. But here it is necessary to ensure shrinkage, otherwise there will be a subsidence at the junction. The roof of the extension is 2-3 cm below the main one. The presence of an overlap will not allow moisture to enter the house.
An additional structure attached tothe main house, is an important object, to which the same requirements are mainly imposed as to the independent structure. Especially important is the addition of the roof to the roof of the house. If the work on erecting this structure is carried out step by step and not to make mistakes, it will be convenient and durable.
