Habitat 67, or simply Habitat, is a model community and housing complex in Montreal, Quebec, Canada, designed by Israeli/Canadian architect Moshe Safdie. It was originally conceived as his master’s thesis in architecture at McGill University and then built as a pavilion for Expo 67, the World’s Fair held from April to October 1967. It is located at 2600 Avenue Pierre-Dupuy on the Marc-Drouin Quay next to the Saint Lawrence River. Habitat 67 is widely considered an architectural landmark and one of the most recognizable and spectacular buildings in both Montreal and Canada. In 2017, Canada Post issued a commemorative stamp for the 50th anniversary of Expo 67 featuring the structure.
Habitat 67 comprises 354 identical, prefabricated concrete forms arranged in various combinations, reaching up to 12 stories in height. Together these units create 146 residences of varying sizes and configurations, each formed from one to eight linked concrete units. The complex originally contained 158 apartments, but several apartments have since been joined to create larger units, reducing the total number. Each unit is connected to at least one private terrace, which can range from approximately 20 to 90 square metres (225 to 1,000 sq ft) in size.
The development was financed by the federal government, but is now owned by its tenants, who formed a limited partnership that purchased the building from the Canada Mortgage and Housing Corporation in 1985. Safdie still owns a penthouse apartment in the building.
