Upside Down House, Gettorf, Germany
This upside down house was built in March 2010 for a local zoo in Gettorf, Germany. Local carpenter Gerhard Mordhorst and his colleagues Gesellse Splettstosser and Manfred Kolax put the unusual building together. The 'crazy house' is reminiscent of a home described in Roald Dahl's children's book The Twits. This house was thought up by Hamburg investor Dirk Oster.
