Commissioned by urban dialogues as a mobile and flexible exhibition display for 9UB with the additional support of the BKA – Bundeskanzleramt Österreich and id22 – institute for creative sustainablility,  ISSSresearch&architecture started a participatory design process involving the Youth Theatre Office in Berlin and students of the DIY – DIT summerschool from the BTK – Berliner Technische Kunsthochschule. The exclusive use of recycling material was made possible by support from the MingaNetwork, who provided wood from former exhibition stands, the BSR-Berliner Stadtreinigung, who sponsored trash container wheels, Holz Possling that provided screws and other necessary metal elements and the re-use of leftover materials from previous projects. Special thanks go to Raimund Binder, Chiara Ciccarello, Ferdinand Schmelzer and Christoph Wiesmayr who supported the project with their energy and enthusiasm.
