Currently, electronic devices transport the self to virtual realities, blur public with private, even the innermost, and provide a foretaste of a different domestic spatiality. Facing this challenge, and taking a resistant stance, architecture turns its gaze to the recent past and is capable of constructing a privacy in which materiality still preserves its full evocative power. The third volume of the GENEROSITY series is dedicated to delving into how this privacy is built in the collective housing environment.
