GFC Antriebssysteme GmbH is looking back at more than 100 years history of developing and manufacturing of worm gear and hydraulic gear units at its enterprise location Coswig near Dresden. The existing production hall was established a faceless, simple box in standardized construction way from precast concrete parts. The existing building did no longer meet the requirements to modern jobs and an increased place requirement within the logistics area. We decided to use the structure of armoured concrete, which was in a good condition and to extend the original building with a two storeyed administration building, logistics and stock area. The spatial connection between administration and production is made by wide glazings in both levels. Different materials signify different functions. The administrative tract is coated by walls from exposed concrete, production and logistics are characterized by the use of shingles from stainless steel and translucent boards from polycarbonate. The large, calm surfaces stress the sculptural character of the whole body. The carrying structure of the office area is done as a grid from columns and beams from exposed concrete. The support structure is slanting in two directions, forward and sidewise and thereby the facade along the railway line Dresden-Berlin creates a motion impelling model. The movement arising from this skew is continued in the facade around the entire structure.
