The Klein bottle is a well-known and interesting surface similar to the Mobius strip. In mathematics, the term means a closed nonorientable surface (a two-dimensional manifold) with no identifiable “inner” and “outer” sides. Ideas of the German mathematician Felix Klein intrigued architects from Charles Ryan McBride who wanted to create something unique. The result is original, futuristic Klein Bottle House, located near Melbourne, Australia. It revolves around a central courtyard, a grand regal stair connecting all the levels. Also you may notice origami stylization. Despite the complete creative freedom, inspired by the mysticism of mathematics, there are usual rectangular rooms inside for comfortable living. The House has won many prestigious awards including World Best House 2009 (World Architecture Festival), Best International Home 2010 (Grand Designs).
