Housing is the space where we find privacy and where we carry out an important part of our daily activities. In contrast to this, in recent decades in Spain housing has become a driving force, often for speculation. In order not to neglect its social function, that of generating a dignified habitat for citizens, it would be necessary to revise the paradigm with which housing is conceived, to understand it not so much as an object that is finished at a given moment, but as a scenario that transforms itself and adopts different spatial configurations over time. Spatial flexibility, user participation and organisation, and user management can be strategies of flexibility and typological design that allow housing to adapt to people’s changing needs. Personalisation, interaction and participation throughout the lifespan may offer a new opportunity for housing.
