The new production hall on the outskirts of Hettenhausen was intended to show what the company does – manufacturing and assembling glass façades, metal construction and interior finishing – while allowing the clients to construct as much as possible themselves. Hence the architect designed a two-storey, flat-roofed hall using steel skeleton-frame construction with a rein-forced concrete core. A double reinforced concrete wall on the west side strengthens the building further and functions additionally as thermal mass. The hall is glazed to the full height of the building on three sides, signalling openness and transparency. Production is open and visible on the ground floor, offices and reception are arranged along the south façade on an intermediate level. A glass dividing wall allows visual contact with the hall and unrestricted communication between the planning and manufacturing departments. The exterior is characterized by a modular grid of horizontal formats.
