Short description of the project Arrangement of two independent, structurally similar membrane roofs over a restaurant building at the shoreline of lake Constance.
The both membrane roofs are put together in a special angle and covers the service- and the accommodation part of the new restaurant building.
The wave-line shape of the roofs corresponds to the environment and offer a great atmosphere of lightness to the visitors. Several curved frame tubes and one circumferential border cable are used as boundary structure for the curved membrane fields.
The membrane forces are shortcut in the upper beam structure itself, so it was possible to build the structure without any tie down cables.
Description of the environmental conditions The isle of mainau is a well-known holiday resort at lake Constance in south west Germany. The small island near Konstanz is generally known for his colourful botanical garden.
