The D Haus is an incredible home designed by David Ben Grunberg and Daniel Woolfson that can morph into 8 different configurations. The home rotates and moves in order to follow the sun, the seasons and the will of the owners. Originally, the house was conceived to be built in Finland, but now the design has been adapted to be built anywhere. The D Haus has a particularly pointed design. This shape was inspired by the mathematical formula to turn an equilateral triangle into a square.
I question how easy it is to actually morph the home, and how often the owners use this feature of their home. It would be fun to have people over for the night, and then change the whole set-up of the house for when they wake up, just to mess with them -- oh, the possibilities.
