Citizens leave town to rest in other places: houses, sheds, and also sites more organized like sea resort or mountain resort. Leisure areas have often been both the counterpoint and the mirror of this new urban order.

At the XXI century, the space mutation due to human activity entails new meanings. Indeed depletion of fossil energies and pollution consequences lead to reconsider ways of wasting space and raw material for building, organizing urban economy and for inhabiting territories.

Nowadays imagining a sustainable minimum house for leisure entails new resolutions in technique, spatial and social fields linked to a new sense of responsibility, in which the technical invention supports a new economy of inhabited space. (Jana Revedin, GAU:DI)
