The project represents a system of elements for assembling wooden houses and is designed for adapting to different type of terrain- from plain to medium sloped, and this is possible because of the designed spot concrete foundations. The building designed for example is one-storey with dimensions 12,94/ 7,56 m. The surrounding panels are wooden with thermal insulation filling protected by water-and-vapor insulation and finished with cement fibre-boards and OSB. The wall panels are supporting walls. By assembling to each other they form supporting columns on which wooden beams bearing the roof are mounted. Bolt-and screw connections are designed to allow the assembly and disassembly of the prefabricated surrounding walls on the site.
