The Klein Bottle House is located in Rye, Australia and designed by Rob McBride. The unusual home design was inspired by its namesake: the Klein bottle. This 19th century invention has no distinguishable inside or outside. The house recently won the Harold Desbrowe-Annear Award in architecture. It is made from concrete sheets and black metal, which are both folded and twisted to create a multitude of angles.
