The subject of this bachelor’s thesis is the preparation of project documentation for the construction of a residential apartment building. The building is located in the cadastral area of Bystrc in the city of Brno on plot no. 678/1. The apartment building has four above-ground storeys and is fully basemented, with a flat green roof. The first and the top above-ground storeys differ in layout from the second and third above-ground storeys. The above-ground storeys contain 10 residential units intended for housing approximately 20 people, a common room, a bicycle and pram storage room, and a ventilation machinery room with a separate entrance. Access to individual residential units is provided exclusively through common areas such as corridors and staircases. The basement includes storage cubicles assigned to each apartment, a cleaning room, a heat exchange station, a server room for the photovoltaic system, and a room intended, for example, as a fitness area. The structural system of the building is a transverse load-bearing wall system. Both external and internal walls are made of Heluz ceramic blocks; the perimeter walls in the basement are reinforced concrete, as is the elevator shaft. The building is founded on a reinforced concrete foundation slab. The building is insulated using an external thermal insulation composite system (ETICS) composed of mineral thermal insulation boards Rockwool. The insulated façade is designed in a combination of white and light brown colors. The frames of external openings are anthracite-colored. The floor structure is designed as a reinforced concrete slab. The staircase is also designed as a monolithic reinforced concrete structure. The roof structure consists of a green flat roof bounded by a parapet.
