With provocative and sculptoresque projects, Stefan Eberstadt (1961) works in Munich (Germany) where teaches at Academy of Fine Arts. In parallel with Eberstadt’s academic career, his projects can be seen all around Germany. The most famous of it is the Rucksack Haus, attached in September 2004 in a Leipzig residential building façade. The sculpture, wich is also habitable, consists in 2,50 x 2,50 x 3,60 m box supported by cables. It has been called “backpacking house” and may be installed anywhere, according to the owners’ wish, as Eberstadt has idealized.
