A construction permanently connected with the ground, with foundation, separated by means of construction partitions (walls and covers), i.e. surrounded by walls and covered by a roof, with or without a cellar, together with built in plumbing, sewerage, heating, electrical gas and other installations, as well as with built in furniture constituting normal builing installations.

A separate building is a building separated from other buildings by free space, and in case of being directly adjacent to other buildings (e.g. in buildings joined under one roof but serving various economic functions), a building separated by gable walls. In semi-detached or terraced residential buildings, each segment containing a separate exit to a lot, street or garden is considered as a separate building.
