Annex to the house from the frame (photo)

How to make an extension to a private house, many owners of suburban areas would like to know. And no wonder. After all, this is a great opportunity to expand the area of ​​a residential building, spending a minimum of money. In fact, the construction of such a structure is a rather simple procedure. However, it is still necessary to have an idea of ​​some features of the technology of its assembly.

Stages of work

An extension to the house from the frame in several stages is being built:

• A project is being drawn up.
• The foundation is being built.
• Going wall frame.
• The rafter system is mounted.
• The roof and walls are sheathed.

Next, we consider what should be the order of work at each of these stages.

How to make a project

Of course, frame extensions to the house are being built (photos of which you can see on the page) with preliminary drawing up of drawings and diagrams. The development of the project will avoid unnecessary costs during the construction of the extension, as well as correctly calculate the amount of necessary materials. The first thing to decide is the area of ​​the future structure and its height. Then they decide how many slopes there will be at the roof of the extension. The choice in this case depends mainly on the architectural features of the building itself. Most often, small-town outbuildings are being erected in suburban small houses. The angle of the rafters depends on the type of roofing material chosen.

The design of such a structure as an extension to the house from the frame should include a detailed diagram indicating all sizes. It’s also nice to attach to it:

• Proportional sketch or 3D model.
• Drawings in profile and frontal projection.
• Detailed plan.
• A sketch of the house itself with an extension.
• Drawings of important connection nodes.
• Foundation scheme.
• Roof scheme.

How to legalize an extension to the house?

Getting permission to build an extension is still at the stage of designing the project. For this, the following documents should be submitted to the local government:

• Application for permission.
• A document confirming the ownership of the house.
• Copies of the data sheet.
• Certificate of registration of each resident.
• Project coordination in architecture management.
• Written consent of all residents.
• Help message received at BTI.

So, now you know how to legalize the extension to the house and how to draw up its project. Next, we will see what exactly will need to be purchased for its construction.

What materials will be needed

To build an extension you will need to buy:

In addition, you will need to purchase the following tools:

• Screwdriver and hammer.
• Concrete mixer, shovel, buckets.
• Scissors for metal.
• Roulette, square.

Base fill

At the first stage of the construction of such a structure as an extension to the house from the frame, marking is carried out for the foundation. In this case, you can use the method of the Egyptian triangle or two arcs.

Further, pegs are driven into the corners of the future foundation, between which a cord is stretched. It is necessary to mark both the outer contour of the concrete strip and the inner one. The width of the foundation is usually equal to the thickness of the walls plus 10-15 cm. The further procedure will be as follows:

• According to the marking, a trench is excavated. Its depth should be equal to the level of laying the foundation of the house itself.
• The bottom of the trench is carefully leveled.
• Then sand is poured into it with a layer of at least 5 cm.
• Stripes of roofing material are spread on the sand.
• Then poured concrete about 3-5 cm thick.
• While the cement mixture will harden, you can do the manufacture of formwork. They knock it down from 2 cm thick boards and 40 * 40 cm boards.
• At the next stage, they begin to assemble the reinforcing cage. The rods are connected to each other by wire.
• After installing the frame, the tape is poured with concrete. This must be done in tamped layers. Top concrete should be installed anchor bolts, which will be attached to the lower harness.

After laying the concrete mixture, the tape is leveled on top, using the level, and left to stand for a month. Formwork can be removed after a couple of days.

The annex to the wooden house is frame, just like to a concrete or brick house, it can also be erected on a columnar foundation. Such a base will cost less. The choice of the variety of the foundation largely depends on the characteristics of the soil in this particular area.

Installation of the lower harness

The foundation tape is pre-waterproofed. Bars of the lower harness are mounted on anchor bolts. Previously, each element is laid on the foundation and tapped with a hammer. Holes are drilled in the resulting dents. Next, the beam is laid on the tape, passing through them the rods of bolts. Mounting is made on hex nuts with wide washers. In the corners of the bars are connected by the method of "half-tree". Further to the finished lower harness, lags are attached to the corners. Then they are trimmed with a edged board.

Rack Installation

At the next stage of the construction of such a structure as an extension to a residential building, they begin to install racks. The first to fix the corner. Further - intermediate. The distance between these elements should be slightly smaller than the width of the insulation boards. The step at the locations of windows and doors is calculated based on their size. Having installed several racks mounted on galvanized steel corners, they are leveled and fixed in this position with temporary jibs. Next, proceed to install the next "party". In the event that in the future it is planned to assemble a single-pitched roof, the length of the racks along the width of the structure is calculated taking into account the angle of its inclination.

It is worth knowing that the frame extension to the house is not rigidly fixed. Unlike the building itself, the new structure will be upset. If you attach the extreme racks to the wall, cracks will certainly go along them.

Installation of the upper harness and the installation of floor beams

After all racks are installed, their verticality is once again checked by level. Next, proceed with the installation of the upper harness. The fastening of its bars to the racks is also made on steel corners. To the finished upper harness perpendicular to the wall of the house, floor beams are mounted. At the final stage, temporary jibs are removed and the racks are fixed permanently (two for each).

Sheathing and insulation of the ceiling

At the next stage, a vapor insulator is mounted on the floor beams from below on the bars. Next, a trim board is mounted on the resulting crate. After that, insulation plates are installed between the beams. Then the boards are stuffed on top.

Rafter system assembly

The annex to the wooden house frame, as already mentioned, is usually covered with a shed roof. In this case, the installation of the roof frame of the structure begins with the installation of intermediate racks under the rafters along the wall of the house. Next, the rafters are cut and fixed to the run and the lower harness. Fixation, since wooden structures give quite a considerable shrinkage, are performed on special “slide” fasteners, which ensure their mobility.

Warming and wall decoration

The frame extension to the house is sheathed in the following order:

• A vapor isolator is mounted inside the annex.
• Plywood is mounted on top of it.
• Between the racks, the insulation boards are installed.
• From above they will need to be closed with a waterproofing film. Like a steam insulator, they attach it to the bars.
• A siding or lining is mounted on the resulting counter-lattice.

Roof sheathing

Previously, on the rafters across, with a slight sag, the waterproofing film is fastened with the bars . Then they fill the crate from a narrow board. Sheets of metal are fixed on it with self-tapping screws.

On this, the process of assembling such a useful structure as an extension to the house from the frame can basically be considered completed. Then it remains only to put the windows, hang the door, knock down the porch and finish the finish from the inside.
