Habitat 67 began as a McGill architecture student's thesis and ended up as the defining image of Expo 67. Moshe Safdie was 26 when his idea — a dense, humane alternative to both the suburban house and the concrete tower — was chosen as a pavilion for Montreal's world exposition. The result, completed in 1967, is 354 prefabricated concrete boxes stacked and interlocked into a cascading ziggurat on the Saint Lawrence River.
The proposition was elegant: give every apartment the qualities of a house — a private garden terrace, fresh air, multiple exposures — while achieving the density of a city. The modules were cast in a factory, fitted out, and craned into place, each one a complete room or set of rooms. No two of the roughly 150 residences are alike, and the gaps between the boxes become the gardens, streets, and sky-wells of a vertical neighbourhood.
It was never repeated at scale — the economics of custom prefabrication defeated the imitators — but the building outlived the exposition and became one of the most photographed housing projects on earth. Designated a Montreal heritage monument in 2009, Habitat 67 now reads as both a period piece and a prophecy: the questions it asked about density, privacy, and the industrialisation of housing are the questions cities are asking again.
