Habitat 67 is a one-of-a-kind housing complex located in Montreal, Quebec, Canada.

Habitat 67 developed out of architect Moshe Safdie’s 1961 thesis design project and report ("A Three-Dimensional Modular Building System" and "A Case for City Living" respectively). The building was realized as the main pavilion and thematic emblem for the International World Exposition and its theme, Man and His World, held in Montreal in 1967.
