Celebrated Italian architect Renzo Piano, of the Renzo Piano Building Workshop (RPBW) designed a tiny cabin on the Vitra Campus called Diogene. The structure is very much built as a retreat and one that could function in various climates. It supplies its own power with photovoltaic cells and solar modules, and the needed water is collected in a rainwater tank, and cleaned and reused. The house is meant to provide you with what you need and nothing more, and that’s just what it does. The front space is the living room with a pullout sofa on one side and a folding table on the other underneath the window. Behind the partition is a shower and a toilet, along with a kitchen. We want one!
