Hans Hollein is an austrian architect. He designed this inflatable mobile office where he can work when and where he wants to.


He developped this "parasit cells" which are mass-produced in factories and can be fixed to a facade in order to extend a space.


In 1972, the Austrian architecture collective Haus-Rucker installed Oasis Nr 7 at Documenta 5 when the environental pollution and potential catastrophe started to be an important concern.

A steel pipe structure was cantilevered out the window of the Friedericianum, and a platform, two palm trees, and a hammock were installed. The entire thing was enclosed in an 8-meter translucent vinyl bubble.
