As part of the first Darmstadt architecture summer Franken Architekten developed a BDA guerrilla urban space action. Selected buildings and objects were assigned with tape art and were alienated. In the distance, the tapes provide a graphical oversubscription of the girder. They change the usual ingredients of public space and perception, highlight and simultaneously call them into question. The questions on the tapes should stimulate to an interaction with architecture and the urban space.
