To design a single-family house is to focus on one of architecture’s key issues – the design of permeability. Since its origin as both shelter and inscription, architecture has been concerned with the separations and passages between indoors and outdoors, something decisive when articulating the need for privacy and protection with the need for territorial demarcation. But at the same time the dwelling is also the programme in which the building and its inhabitants establish a greater intimacy, and in which the profanation of the object by its users becomes a key element, therefore reinforcing the idea of architecture as collective practice, existing only as far as inhabiting takes place.
