An apartment building with built-in premises, an attached underground car park and a closed-type multi-storey car park is designed on the site. The assignment for the design of the construction is provided in 2 stages. Stage 1 of construction - an apartment building with built-in premises and an attached underground parking lot. 2nd stage of construction - closed-type above-ground car park. The apartment building is designed as a four-section (sections A, B, C, D) multi-storey (14, 17, 19 floors, including a technical attic), in a L-shaped plan. The size of the residential building in the plan is 1 m in the axes "6-95,40", and 66,45 m in the axes "A-G". The height of the building from ground level to the top of the parapet is 59,12 m (to the top of the machine room of the elevators 60,32 m). The residential building is classified as category B in terms of comfort. In the basement floor, technical rooms for engineering support of the building are designed - ITP of the residential part and built-in premises, main switchboard, water metering unit, ventilation chambers, fire extinguishing pumping station, technical rooms, cleaning equipment room. An attached underground car park for 185 cars has been designed at the basement level. Built-in premises are provided on the 1st floor of the designed house: three insurance agencies, three premises for operational services. On the 1st floor, apartments, entrance areas to the residential part of the building with elevator lobbies, waste collection chambers, a control room and a homeowners association are also designed. On the 1st floor of section B, a through passage to the yard area is designed. In an apartment building, in accordance with the design assignment, one-room, two-room, three-room apartments and studio apartments (apartments with kitchen niches) are designed from the second floor and above and, partially, on the 1st floor. Starting from the third floor, balconies with stained-glass windows are designed. The technical attic is provided for laying engineering communications. The height of the first floor in sections is 3,3 meters (from the level of the finished floor of the 1st floor to the level of the finished floor of the 2nd floor). The height of the remaining residential floors is assumed to be 3,0 meters. The main entrances to the residential sections of the house are designed from the side of the courtyard. Entrances to the built-in premises are designed both from the side of the courtyard and from the side of the main facade. Each residential section has two elevators with a carrying capacity of 400 kg and 630 kg with a machine room. For access of the residents of the house to the parking lot, elevators are provided in the stair-lift blocks, having a stop at the level of the underground parking lot. Passage to these elevators from the parking area is provided through a vestibule with air overpressure. The outer walls of the apartment building above 0,000 are designed as non-bearing, brick, insulated with mineral wool slabs and subsequent cladding with porcelain stoneware (ventilated facade system). The monolithic reinforced concrete walls of the basement and the parking lot are planned to be insulated with extruded polystyrene foam slabs above the blind area with the facade surface facing with Melikonpolar concrete decorative stone. The decoration of the facades of the 1st-3rd floors is designed from Melikonpolar decorative stone - 120 mm (granite color), above the 3rd floor - from porcelain stoneware slabs on a metal frame according to the ventilation facade system (light yellow with white inserts). Socle - facing with concrete decorative stone "Melikonpolar". Finishing the facades of a technical attic - painting with facade paints on a plastered surface. Internal interior partitions are designed from expanded clay-concrete stone. Window blocks - metal-plastic with two-chamber double-glazed windows. The design documentation for the yard area includes: an underground attached parking lot for 185 cars and a multi-storey above-ground closed-type parking lot for 107 cars, with independent entrances and exits. The multi-storey above-ground car park is designed based on the structures of the underground attached car park. Entry-exit to the underground car park is provided by a covered double-track ramp through the overhead sectional gate. Entry-exit to the multi-storey closed-type car park is designed to the 1st floor directly from the ground level through the lifting sectional gates, the rise to the 2nd-3rd floors is along a single-track ramp. At the entrance to the car parks there are automatic gates that open with the car user's electronic key. The outer walls of the above-ground parking lot are hinged sandwich panels with an outer finish of the basement with concrete decorative stone "Melikonpolar". The roof of the above-ground car park - with a roll-up cover and external organized drains.  Block complete transformer substation (2BKTP) is developed according to separate design documentation. The project documentation provides for a set of measures to ensure accessibility to all entrances to the building and movement around the site, to the entrance to the residential building for disabled people in wheelchairs. For access of disabled people in wheelchairs to the level of the first floor of a residential building, built-in premises and HOA, it is planned to equip all flights of stairs with stair lifting devices with a platform - BK 350. For access of disabled people in wheelchairs from the apartment to the parking lot from each section of the residential building passenger-and-freight elevators with a stop in the parking lot are provided.

Structural and space-planning solutions

The required fire resistance of structures is confirmed by calculations. The level of responsibility of buildings is the second (normal). The service life of buildings is assumed to be at least 50 years. The mark of the floor of the first floor, corresponding to the absolute mark of 0,000, was taken as 12.80. The foundations are developed in accordance with the results of engineering and geological surveys performed.
