Shared space is a common space shared by two or more dwellings, but which does not necessarily have to be used simultaneously. The potential that lies in shared spaces have not really taken into consideration on the field of study or practice. The research of flexible housing has mainly focused on private homes and their internal flexibility while the concept of sharing spaces hasn’t very strongly come up. The changing lifestyles and ways of living, as well as demographic changes require flexibility in housing. Shared spaces are one way to get closer to this aim.
