How did the Charterhouse of Ema influence Le Corbusier’s ideas about housing?

During his travels between 1907 and 1911, Le Corbusier visited the Charterhouse of Ema at Galluzzo, Italy, which became a foundational influence on his architectural philosophy.1

The monastery provided him with a compelling contrast between vast, shared collective spaces and small, private "individual living cells". This organizational model served as the basis for his later conceptions of residential buildings, where he sought to balance communal living with private domestic space. This influence is notably reflected in his design for the Unité d’Habitation in Marseille, a vertical community that incorporates shared services and "streets" within a structure composed of individual, stacked apartment units.12
