Architectural and space-planning solutions

The building to be reconstructed to accommodate a multifunctional shopping and entertainment center is located in a block of existing development, limited by streets. The building is detached, two-storey, brick, with reinforced concrete ceilings and riveted metal trusses above the hall, without a basement, rectangular in plan, built in 1883. During the operation, the building was overhauled. The entrance and access to the building is carried out from the side of the main facade from the street, oriented to the west, and there are also entrances from the southern and northern facades. The building is not an object of cultural heritage. At a distance of 21 and 24 m from the reconstructed building there are objects of cultural heritage. According to the section of the project Volume 12 "Measures to ensure the preservation of cultural heritage sites", the zone of influence of reconstruction on cultural heritage sites is 8,1 m. The surrounding cultural heritage sites are outside the zone of influence of the planned construction works. The project documentation provides for the reconstruction of the building into a multifunctional shopping and entertainment center for organizing celebrations, bowling and billiards competitions. Provision is made for the sale of culinary and confectionery products in the restaurant block.

The project documentation provides for the placement of three functional blocks in the building: a block of restaurant premises, a block of entertainment center premises, and a block of administrative premises. The height of the building from the planning mark of the ground to the roof ridge is 13,825 m, the existing one is preserved. On the ground floor, it was designed: a hall, a wardrobe, a vestibule, technical premises for the operation of the house (a heating point, a water metering unit, an electrical panel room), a block of restaurant premises with production, auxiliary and sanitary facilities; a block of premises of the entertainment center with halls, a security room, wardrobes, locker rooms, sanitary facilities, billiard rooms, a multifunctional hall, storerooms and auxiliary and administrative premises for staff. On the second floor, it is planned: a hall, restaurant premises (recreation area, administration offices) with an internal staircase connecting the ground floor restaurant hall, a block of entertainment center premises with premises: halls, bowling halls and areas, technical premises, lamp storage room, staff room ; a block of administrative premises with sanitary facilities. A ventilation chamber is designed in the attic. The vertical connection between the floors and the evacuation from the building is designed through L1-type stairwells with exits to the outside. Exits to the roof are provided from the attic. The height of the premises from floor to ceiling: on the first floor from 3,00 to 6,70 m, on the second floor from 2,8 to 4,8 m. Windows - metal-plastic filled with double-glazed windows.
