Expo 67 was nicknamed "Man and his World", taken from Antoine de Saint Exupéry's memoir Terre des hommes (literally "Land of Men"), translated as Wind, Sand and Stars. Housing was one of the main themes of Expo 67. Habitat 67 then became a thematic pavilion visited by hundreds of thousands of visitors who came from around the world. During Expo 67 it was also the temporary residence of the many dignitaries coming to Montreal.
It was designed to integrate the variety and diversity of scattered private homes with the economics and density of a modern apartment building. Modular, interlocking concrete forms define the space. The project was designed to create affordable housing with close but private quarters, each equipped with a garden. The building was believed to illustrate the new lifestyle people would live in increasingly crowded cities around the world.The complex was originally meant to be vastly larger. Due to its architectural cachet, demand for the building's units has made them more expensive than originally envisioned.
The building is owned by its tenants, who formed a limited partnership that purchased the building from the Canada Mortgage and Housing Corporation in 1985.
Its design was created by architect Moshe Safdie based on his master's thesis at McGill University and built as part of Expo 67.
