In the middle of the up-and-coming growth district of Berlin-Spandau, Klingsöhr has added an attractive new office building to a listed ensemble. The representative multi-storey building named WILHELM23 with its clinker brick façade blends harmoniously into the historic townscape. The approximately 400 m² floors offer all the design freedom necessary for sustainable corporate success. WILHELM23 combines sustainability, down-to-earthness and flexibility - the rooms, including a spacious roof terrace, offer contemporary comfort and can be adapted precisely to the needs of the tenants.
