Project of a two-story small brick house up to 170 sq.m. with a garage.

Convenient and easy to build. Economical project houses with 2 floors with total area up to 200 sq.m.

The house design provides small balcony from the bedroom on the second floor. One of the bedrooms on the second floor can be converted into a children's room. Optimal layout convenient for a family of 5-6 people. The house has a small attached garage to store one car. At the customer's request, the garage can be extended to the left to store two cars. A cozy and spacious living room on the ground floor of the house will become a comfortable gathering place for the whole family for an evening meal.

The price of construction of the presented house without interior decoration premises 2.4 million rubles, for comparison the cost studio apartment in the city of Belgorod in prices as of September 1, 2014 is 58-60 tr. for 1 sq. m. in a new building. Build a house yourself and you will receive: 1. Personal living space built to suit your preferences. 2. Comfort and environmental friendliness of country living. 3. A way to save money by purchasing housing for yourself and your family.

Concerning exterior finishing at home, preference has recently been given to facing bricks. But siding and classic cement-sand plaster are still popular. It is also possible to apply frescoes and mosaics to the facade, but this is a rather labor-intensive and expensive type of finishing.

The final result depends not only on preferences and financial resources the customer, but also on the level of professional qualifications of the builders.

The total area of ​​the house is 160 sq.m.

The cost of the house project is 8000 rubles.

For a 20 kW boiler, a chimney with an internal diameter is suitable 160 mm and height 7 m.

The degree of insulation is determined based on the total heat loss of the building and depends on the material, thickness and number of layers:

  • - enclosing structures
  • - walls;
  • - wall insulation;
  • - roofs;
  • - roof insulation;
  • - roof coverings;
  • - floor insulation;

And also on the type and area of ​​glazing and entrance openings.

Examples non-insulated buildings:

The walls are single-layer (without insulation), made of material with a thermal conductivity coefficient above 1.300 - concrete on crushed stone, reinforced concrete, solid concrete...

Roof and floor insulation is single-layer or absent.

Examples of buildings with a low degree of insulation:

The walls are single-layer, made of material with a thermal conductivity coefficient from 0.440 to 1.300 - silicate brick, ceramic brick, slag brick, red clay brick, FBS block, alabaster slab, hollow brick.

The floor and roof are insulated.

Examples of buildings with an average degree of insulation:

Mostly single-layer, made of material with a thermal conductivity coefficient from 0.090 to 0.440 - TEPLOSTEN block, multi-layer construction cardboard, wood, silica brick, ceramic brick, thermal insulating concrete, wooden beams, plasterboard, expanded clay concrete, foam concrete, building gypsum, ceramic brick (hollow), hollow brick.

The floor and roof are insulated.

Examples of buildings with a high degree of insulation:

Mostly two- or multi-layer, walls and insulation are made of material with a thermal conductivity coefficient for walls - up to 1.000, for insulation - from 0.001 to 0.085 - polyurethane foam, fiberglass, polystyrene foam, polystyrene, expanded polystyrene, foam rubber, mineral wool, glass wool, dry sawdust.

The floor and roof are insulated.
