For communication between floors there is a two-march closed staircase. The building has one exit outside.

Balconies, a veranda staircase, a platform on the attic floor are equipped with railings.

The facade is finished with face brick. Window and door openings are made with quarters and widens along the perimeter. The corners of the building are also widened.

The walls are three-layer (brick bearing part 250 and 380 mm, insulation 100 mm made of polystyrene foam plates, face brick 120 mm).

The building slabs are made of 220 mm prefabricated hollow flooring. The flooring includes a noise-absorbing layer of wood-fibrous boards and expanded clay.

Filling of window and door openings is carried out with plastic windows and doors with double double double-glazed windows, the front door is steel. Fabrication of window and door blocks is performed upon the fact of opening.

The roof of the building is four-pitched with an external organized drain. The roof is made of metal cuttings according to a grate, counter-grate and wooden rafters. Insulation (polystyrene foam boards) is laid between the rafters. Channels for ventilation of internal layers of coating are provided. Access to the roof is provided by an attachment staircase and running stairs.

Flooring in the main rooms is performed by laminate, in bathrooms - by ceramic tiles.

Brick partitions 120 mm thick, gypsum board 100 mm thick. Lintels in brick walls and partitions are made of rolling profiles.

The internal surfaces of brick walls and partitions are plastered, painted with water-emulsion paints.

On the 1st floor of the building there is a fireplace. The thickness of the walls of the fireplace and the ceiling is 250 mm. The inner verst (120 mm) is made of refractory brick. The fireplace furnace hole is closed by a door made of heat-resistant glass. On the floor in front of the fireplace, a pre-fireplace made of ceramic tiles measuring 500 mm from the front wall of the fireplace is laid out. On the sides, the boundary of the platform is not less than 200 mm from the furnace hole on each side. Side walls of smoke collector connecting fireplace furnace with chimney are made with inclination of at least 45 ° to horizontal.

Design Solutions

The foundations for the building are tape from FBS units, monolithic columnar verandahs for columns.

Bearing external and internal walls are made of red brick of ordinary thickness 380 mm, brand M75, as well as a layer of insulation 100 mm and face brick 120 mm.
