Apartment floor plans have a decisive influence on our lives. In the last 30 years, Swiss housing architecture has successively introduced the new ideal of floor plans with open and flexible uses. The aim is to offer spatial qualities to residents who are not yet clearly defined, thereby fulfilling the changing requirements of a diverse society. This publication presents five Swiss architects providing insight on their “good plans” with short texts and images: Elli Mosayebi (EMI Architekten); Jeannette Kuo (Karamuk Kuo Architects); Maria Conen (Conen Sigl Architekt:innen); Lütjens Padmanabhan (Lütjens Padmanabhan Architekten); Philipp Esch (Esch ­Sintzel Architekten).
