VitraHaus

This unique architectural creation is called the VitraHaus. It was designed and built by Swiss architects Jacques Herzog and Pierre de Meuron of Basel-based architecture firm Herzog & de Meuron Architeckten. It is located in Weil am Rhein, Germany on the Vitra Campus and is used as a showroom for the Vitra Home Collection. This crazy design looks like a dozen houses, like the ones you drew as a kid: a square with a triangle on top, haphazardly stacked on top of one another. "The concept of the VitraHaus connects two themes that appear repeatedly in the oeuvre of Herzog & de Meuron; the theme of archetypal house and the themes of stacked volumes." The whole structure is 5 stories tall and is made up of 12 houses. The interior is very open with high ceilings and long spaces and large windows letting in a lot of natural sunlight. The large windows also allow the houses to look lit up at night.

Here is a good photo gallery showing the exterior and interior of the VitraHaus.
