The exterior is made up of aluminum and includes solar panels and a rainwater collection system, meeting the demand for electricity and water.

Inspired by the idea of a simplistic home, Piano created the self-sufficient solitary retreat that measures under three meters on each side, and says about his project, 'This little house is the final result of a long, long journey partially driven by desires and dreams, but also by technicality and a scientific approach.' The ancient thinker was known for his Cynicism, viewing society as corrupt and promoting a simple lifestyle, as he established his place of shelter and rest in a large ceramic jar. Named after the Greek philosopher Diogenes of Sinope, the wooden unit is a small home designed to fit and host one person and his/her necessary living accommodations.
