- 1993 to 2004: Station building Markkleeberg-Großstädteln (near Leipzig)
- Since 2004: New company building in the industrial area Wachau (near Leipzig)
Despite numerous renovations and enlargements for the research and development department (R&D), the space in the formerly rented building had become insufficient. Therefore, a new building was established in the industrial area Markkleeberg-Wachau. It meets all requirements concerning modern R&D work places and enlargement of the manufacturing capacity, up-to-date test labs included.
