To create a future-proof, capital oriented system for workshops, a general entrepreneurial team shall be formed under the roof of a "craftsman court" in the city of Bonn. The "craftsman court" is represented by central administration facilities to outside visitors. A special building is placed at the main street. There are flexible big areas and factory buildings for the individual enterprises. The factory buildings can be extended by a universal module, which is equipped with sanitary facilities and office facilities. The buildings are constructed by the "Hebel" building system. The great variability allows the companies to meet the challenges of a changing market.
