Living individually while feeling comfortable within the framework of a collective building: this lifestyle trend is becoming increasingly evident. This inventory of new forms of collective housing in Europe documents forty-five built projects that can serve as models. Selected by leading international architectural critics, all of the buildings—by young, little-known architects as well as by such renowned names as Foreign Office, Manuelle Gautrand, MVRDV, and Miller & Maranta—are presented in texts and images and analyzed according to the same typological criteria.
