Microcosmi documents the didactic activity of Valentin Bearth’s Design Studio at the Mendrisio Academy of Architecture between 2004 and 2012. It describes the methodology and the premises of the course within the context of the school and presents a selection of student projects. The didactic report is completed by the transcription of a lecture by Aurelio Galfetti, where the parallel presentation of two built projects, the Rotalinti House in Bellinzona and his house on the island of Paros, offers a significant contribution on the theme of inhabitation.
