Atelier 5 was an architectural firm founded in Bern, Switzerland in 1955 by five architects. They are renowned for designing the Halen housing development between 1955-1962, which is considered a seminal example of post-World War 2 housing. Atelier 5 was influenced by Le Corbusier and focused on designing affordable concrete housing with an emphasis on private and communal spaces. They designed several other housing developments in Switzerland employing rigorous study of place and context without architectural quotes.
