Wernerwerk High-Rise / Wernerwerk X (1930)

Siemens was constantly expanding and building new buildings. To prevent confusion, in the 1920s Siemens began naming and numbering them as Wernerwerke (Werner’s Factories), after company founder Werner von Siemens. The architect of Wernerwerk was Hans Hertlein. His sober, functional steel-frame buildings set a new standard and were the face of the distinctive Siemens style. This high-rise building once contained the Siemens & Halske offices, a library, and, on the tenth floor, a lecture hall. To highlight the importance of this cutting-edge building and the revolutionary potential of electricity, on special occasions all of the windows were illuminated. The building is now home to several companies, and the tenth floor is a conference center.
