For the 2022 State Garden Show in Beelitz, Textil Bau and its subcontractors constructed the membrane roof for the open-air stage. The structure, made of straight and radial steel tubes, forms the basic framework for the textile covering of the approximately 24-metre-long stage. Special attention was paid to the water drainage of the membrane.

The open-air stage was designed like an amphitheatre, so that spectators can see the Beelitz church tower and the roofs of the town during performances. Events such as the Beelitz Festival are to be held here not only during the State Garden Show, but also afterwards.
