This article will tell you how to make a brick extension to the house with your own hands. You will learn about all the nuances and features of the work, what you need to pay attention to, and how to correctly calculate the cost of the foundation and material for walls.
The construction of brick extensions to wooden houses is planned for various purposes. Someone increases the space in the house, using such rooms as a kitchen, bathroom or pantry for storing things. Also, outbuildings are being built as a terrace or veranda.
An extension to a wooden house is a wonderful way to increase the space. They can be of different sizes and configurations, depending on the wishes of the home owner. The extension can be used as a dining area, a terrace for relaxation or a place to store equipment and things for various purposes. You can build an extension to the house yourself, or contact a specialist.
In order for the newly created extension not to be knocked out of the general ensemble of the building, it is necessary to decide in advance on the style and create a project.
Remember that for an outbuilding, you also need to obtain a permit and order design documentation.
For the construction of a dwelling as an annex, it is necessary to carry out an absolute range of construction works using foam blocks, beams or bricks.
The base is prepared from blocks or a monolith. The roof is erected with waterproofing.
The kitchen area has a more complex design, with ventilation, sewerage and other communications.
You can also attach a brick garage to a wooden house, the roof is made of slate or shingles.
The types of extensions to the house are very diverse, from the simplest to the very stylish and modern. An annex, which is erected from the end of the building, thus, the roof will be common for all premises. Also, buildings can be crafted in such a way that the roof is separate, not combined with the general one. There are annexes, which are being built on the second floor, as a cozy attic with a transparent roof.
Features of a bar as a material:
The timber extension is mounted in such a way that it is connected to the main building. The base is often poured in the same way as at the house.
Voids and holes between both walls are sealed with polyurethane foam in order to prevent wall breakage during the shrinkage of the new annex.
The pile foundation is considered a cheaper option. The walls of the annex are constructed of profiled beams.After the first row is laid, the surface is covered with antiseptics, then logs are laid on the bars. Cracks and voids are filled with a special material for thermal insulation.
Each subsequent row is laid with wood dowels. Corner areas require increased attention. For their laying, logs with a groove and a ledge for a tight connection are used.
Before starting construction it is necessary to pay attention to the peculiarities of the installation of the auxiliary structure to the main building. The size and length of the outbuilding must match the length of the house wall
In width, the design can vary up or down.
An annex to a wooden house may not be adjacent to the wall of the house. The exit can be done from the living room. If a toilet or a bathroom will be located in the annex, it is better to exit from the corridor or bedroom.
Any construction associated with considerable costs finance, materials and manpower need careful thought and design. Incorrect calculations and savings on materials can play a cruel joke in the future.
We'll have to finish something or alter, replace. Therefore, it is better to use the rule "measure seven times - cut once."
Each separate type of annexes to the house has a number of features, depending on what it is intended for.
A living space of the type of a separate room requires careful insulation and waterproofing. You also need to think about how to carry out the heating system in the winter.
In additional annexes, a toilet or kitchen is often located. First of all, you need to take care of the communications that start even before the start of construction. Sewer pipes are easiest to run before laying the foundation. If the kitchen is planned to be used only in the summer, you do not need to insulate.
An annex to a wooden house can be built as a veranda.
It is mounted quite easily, it is used for relaxing in the summer heat, it serves as protection from rain, snow and wind to enter the house. The execution options are varied: like a boardwalk, walls on poles with a roof, as well as windows and doors. In this case, waterproofing is not performed. To harmonize the outbuilding with the house, the decoration is the same.
Wood goes very well with any material.
The white brick extension also looks great.
So, before starting work on installing the extension, you need to take into account the characteristics of the soil and the mass of the structure.If you are waiting for construction on so-called heaving soils, take into account the fact that the base can move during use, and the annex will move away from the main wall of the house. Lightweight foundations will not support heavy walls and will shrink under the influence of weight.
Work begins with laying a waterproofing film, the ends of which are left on the surface.
For pillars made of bricks, concrete is poured into the holes and they wait until it grabs. Fragments of brick are laid down to raise the reinforcement by 4 cm.
Before you start laying out the brick walls of the annex, you need to find out how even foundation. If there are deviations, then it is necessary to do additional work to fix the walls of the extension to the main wall. To do this, holes are made in it during the laying of the walls, at a depth of 2/3 through 3 rows of masonry.
Reinforcement is inserted into them, which should protrude by half a meter and will later be placed in the seams of the masonry. Before laying out brick walls, a rope is pulled along the wall, which will help control the evenness of the rows.
The vertical is checked using a plumb line. The thickness of the walls is determined in advance, taking into account the purpose that the extension will perform. For a living room, masonry is made 1 or 2 bricks thick.
For the kitchen it will be enough - 1/2 brick. At the end of laying out the brick walls, they must be poured with concrete from above.
For this, a formwork is made, in which reinforcement is placed and poured with concrete. After the concrete hardens, it is removed, and work begins on the construction of floors from beams, which act as beams. They are attached to the top of the walls at a distance of about 70 cm and secured with corners.
They can also be embedded in a concrete belt by wrapping them with roofing felt. The roof for a brick extension of a wooden house is most often made of one-pitched rafters.
The slope is done at an angle of 25 - 30º. This will allow snow to slide off the roof safely.
For the foundation, the formwork for the basement is made, the film is run inside.
Concrete is poured in layers, each layer is pierced with a rod to release air.
Align the post from above and wait about 2 weeks until the concrete hardens completely. The entire period is poured abundantly with water and covered with foil or burlap.
After the foundation has solidified, the formwork is removed. Next, a bituminous mastic is prepared, warming it up, and applied to the posts.
Then roofing material is immediately glued for the purpose of waterproofing.
The remaining space between the posts is filled up to insulate the floor. For this purpose, use the earth mixed with broken brick or rubble. Fall asleep in layers of about 10 cm and tamp. The strip foundation is laid according to a similar principle, the only difference is that it is solid.
Once the walls are up, you can tackle the annex floor. The cheapest way is to lay tiled polystyrene foam, the density of which is 15 kg / m³.He is not afraid of moisture, but can not boast of high environmental friendliness.
To insulate an annex of a wooden house, use foam or mineral wool.
Minvata is good because it is not afraid of fire and has a low weight. Polyfoam is a cheap material, is not subject to putrefactive processes, is not afraid of moisture. But we are very fond of rodents, when burning, it emits dangerous gases.
The sequence of insulating a brick annex to a wooden house:
For windows, they choose ordinary plastic double-glazed windows or wooden ones if they want more environmental friendliness.
The choice of doors in our time is extensive, from cheap to expensive. Does not forget about the wiring and installation of lighting devices. Facing work is also carried out at your discretion. You can leave the walls brick, then your extension will resemble the loft style, which is quite popular nowadays.
