The change house with warming provides an opportunity for a comfortable stay in it, regardless of the circumstances. But it also happens that this living space is not enough, then an extension comes to the rescue.

Building options

In most cases, the cabin is an auxiliary room, entering which a person immediately enters the room. There is no free space for the hallway, so additional construction will be very useful.

Did you know? One of the most unusual buildings is rightfully recognized as a building erected from paper blocks, which, in turn, consist of out-of-circulation banknotes. This attraction is located in Ireland.

There are three types that differ from each other in purpose and, therefore, functions:

1. Veranda - A closed, often glazed, small room. Suitable for the location of kitchen appliances. If you put a heating system and insulate the walls, then such a building will be relevant year-round. In addition, you can stay at the summer version of the kitchen and make it a reception area. Often used as a summer residence option.
2. Terrace it is an open area limited by a railing or a balustrade, a canopy is used instead of a roof. Often the room is operated for relaxing in the warm season, it contains a sofa, armchairs, tables, elements of garden furniture, deck chairs, etc.
3. Another way to increase the change house - build porch. This is a small open area (maximum 1.5 m) with steps and a canopy. It can be used as a hallway - in this case, the size of the living space increases significantly.

Preparatory work

When planning to modify a household building, it is important not to lose sight of a large number of features. The extension is always organized from the side of the door, since it is its characteristics that determine the length of the selected structure. The width is determined directly by the owner, and depends on personal preferences, as well as the materials available.

Drawing and site preparation

The foundation scheme directly depends on the extension option and its approximate appearance, so first you need to decide on these parameters, sketch ideas on a piece of paper. The next step is to transfer all preferences to the computer program for creating drawings - there are quite a lot of them, they are simple to use, so this stage will not take too much time. However, it is quite important, because it helps to build all the components symmetrically, rationally in relation to each other.

A fairly simple way, not involving a lot of time, is to search for ready-made drawings on the Internet - often they all go for standard extensions, but you can also find quite unusual ones.

If you are not confident in your abilities, you can choose the simplest, but at the same time the most costly option - contact a construction company. There, in a short time, you can get a ready-made and absolutely correct project in all respects, without worrying that the site being built will collapse.

When the sketch is ready, you can begin to prepare the place. First of all, it is necessary to clean the desired plot of land from weeds, debris, dry leaves, etc. Then arm yourself with a building level, wooden pegs and a rope - with the help of these materials it will be possible to derive the extreme points of the future structure. Further, the extension site must be freed from the topsoil (20 cm), covered with gravel and sand, so that each layer is 10 cm, plus small layer-by-layer rammers.

With correctly completed work, a square or rectangle will have equal diagonals. If the digital values ​​of the segments do not coincide, in no case should you leave structural elements in this form.

Necessary materials and tools

Regardless of the type of construction, the following building materials will be needed:

• wooden boards for the manufacture of lathing 25 mm thick;
• bars of 50 × 50 and 100 × 100 mm;
• reinforcement, rods or mesh;
• boards for flooring with a thickness of 3 cm;
• roofing sheets, combined with the material from which the roof of the trailer is made;
• any desired windows (if the veranda);
• fences and partitions (for a terrace);
• finished railings and jibs or bars for their manufacture;
• regulatory supports - 4 units (necessary if the area of ​​residence has high humidity and the tendency of the soil to subside).

Important! Since the building is temporary, it is recommended to insulate it with inexpensive materials such as polystyrene or glass wool.

The amount of materials taken from the calculation of schematic data. Screws, nails, straight and oblique metal corners, as well as self-tapping screws are used as fasteners.

Tools required:

• hand or chainsaw;
• drill;
• Bulgarian;
• screwdriver;
• electric planer, etc.

Construction stages

Having prepared the desired plot of land, you can proceed to the most time-consuming and lengthy process - construction. Conventionally, it can be divided into five stages: laying the foundation, lower strapping, installation of supports, upper strapping and creating a roof, as well as finishing. Each of them is relevant to any type of construction mentioned earlier, since the construction technique is not very different. Having studied the recommendations and tips below, you can simplify the task.

Foundation laying

If the foundation was not laid at the stage of designing the change house, it is advisable to do it now. In the case of a terrace, this step is optional: previously prepared crushed stone base is poured with cement mortar, wooden logs are laid on top, which protect from dampness, and covered with a special waterproofing mastic.

The wooden frame is attached to the cabins with metal corners. If we are talking about a porch or a veranda, under them you need to put ready-made concrete blocks or create a strip foundation - it is universal, and using a closed circuit, you can prevent future subsidence of the structure.

Did you know? Despite the fact that cement is an extremely important and integral material in the construction process, it has one significant drawback — its production creates an emission of a large volume of greenhouse gases.

The foundation is laid as follows:

1. To buy or create a solid formwork yourself from the beams according to the dimensions specified in the drawing. Mount it in a ditch.
2. With the help of reinforcement (several rods need to be fastened with wire), reinforce.
3. Pour the structure with cement, let it harden completely.

In the case when you give preference to blocks, you need to place them at each extreme point and in the middle, while observing a step of 2-3 meters.

Bottom harness

The wooden frame often begins to be erected from the bottom trim, preferably double. To do this, use bars with a thickness of 100 mm. For fastening them together, screws and metal corners are used. At this stage, the binding should completely repeat the foundation. It is mounted on blocks or fittings. Fixation to the change house itself is also done with the help of corners and screws.

Important! Between wood and cement it is worth installing waterproofing — materials such as roofing material or foamed polyethylene will come in handy.

Installation of supports

At this stage, vertically mounted wooden poles are mounted, following the drawing. The distance between them should be the same, with the help of a level gauge everything is checked for compliance. In the process, temporary fixation of the supports by prepared strong beams (jibs) is used.

When the supports are firmly fixed, it's time to start arranging the subfloor: lay the boards, and then fix them with screws or special fasteners. On top of this, it is recommended to immediately carry out insulation work (flooring glazed floor will be the best solution).

Top harness and roof

The design helps to strengthen the frame in general. The organization of the upper harness - on the same principle as the lower. First you need to dismantle the decorative elements of the change house. It is definitely worth measuring and taking into account the slope of the existing roof. It should be at least 10 cm.

Next, the previously established temporary cuts are removed. The bars of the upper harness are connected to the vertical supports with the help of corners and screws. After that, they choose places for windows and doors, if any. The width of the openings needs to be fixed additional racks and nail horizontal jumpers.

Before installing the roof, it is worth removing the screws from the edges of the existing roof of the change house. The rafters are laid with the lower end on the strapping, the upper ones are connected to the rafters or rest on the run. Next, lay the roofing sheets under the corrugated board.

In the racks, you can make the right number of recesses to make a railing.

Finish

The final stage of the construction of the extension is the decoration of the walls and floors. This is necessary to give the room an aesthetic appearance both outside and inside. To begin with, they lay the final floor, and also insulate the walls.

Then round the outer corners, correct visible defects, if any, remove roughness and often give an unusual shape to some decor elements, which is perfect for an electric plane. Other trim elements are also installed: skirting boards, fillets, as well as platbands and fillers, if windows and doors are supposed to be installed.

Following the step-by-step instructions on the proposed technology, you can attach a terrace, porch or porch without any difficulties, while the appearance will turn out no worse than with professional help. And using modern power tools, you can speed up the process several times.
