Under a green roof

The body of the building consists of two cuboids placed upon each other, connected by interior staircases at the centre point, and a two-level high external conservatory. The community places are located in the ground-floor block; the private rooms and the mechanical part are in the floor areas set at an angle.

Due to energy optimization, only the living spaces are within the insulated shell while the conservatory and the parking place are outside the shell. The conservatory and southern glass surfaces of the living room are equipped with shading: electrically-controlled external shuttering. The parking place is open, established so that the first floor of the building covers it; however, later it can be converted into a closed one by an assembled shell when needed.

The building is of flat roof construction with an extensive green roof. Above the ground floor section there is a roof-garden, and the solar collectors are situated above this floor level.
