For the design of the outdoor area between the town hall and the grammar school, the town of Schloß Holte-Stukenbrock opted for an event area with a permanent membrane roof. The galvanised steel arches of the stage roof have a height of approx. 5.85 m at the front and approx. 5.70 m at the rear. The membrane, consisting of PVC-coated polyester fabric, is divided into two elements, each of which is attached linearly to the trusses by means of clamps. The rear canopy neatly encloses the area to be covered.
