Think Small: Renzo Piano's Vitra House | sustainable architecture |

Vitra’s carefully curated campus in Weil am Rhein, Germany, contains works by Herzog & de Meuron, Frank Gehry, FAIA, and Jean Prouvé, among other top-tier designers. Now the venerable Swiss furniture company has added a tiny prefab house by Renzo Piano Building Workshop to the mix. In 2013, Vitra unveiled Diogene, a 43-square-foot prototype.

In keeping with the no-frills lifestyle of its ancient Greek namesake, the philosopher Diogenes, the house consists of only one room. A slim, ultra-efficient layer of insulation is sandwiched between the cabin’s wood frame and aluminum skin. “The house is really minimal,” says Vitra project manager Aja Huber. “It’s a life where you have to think, do you want the sofa or the bed?”
