The brief required a prototype structure for four forestry stations. The architects designed an elemental system that could be adapted to various locations. This development consists of a raised administration tract, a garage (built in concrete to meet fire regulations) and an open hall. The hollow-section panels in the hall span a width of 5 m and rest on 10 m steel beams with trussed lower chords. These, in turn, are supported by 6- to 8-metre high rough tree stems. The hall structure is braced by diagonal steel cables above the roof. The floor and roof of the administration tract consist of hollow-section beams supported by diagonally braced timber posts.
