Habitat 67 is a landmark residential building complex in Montreal. It was originally conceived as an architectural thesis by Moshe Safdie and later realized as a pavilion for the 1967 International and Universal Exposition, commonly known as Expo 67. The project was designed to explore new modes of urban living by integrating the benefits of a suburban home, such as gardens and fresh air, into a high-density urban environment. The structure is composed of 354 identical, prefabricated concrete modules arranged in various combinations. These modules form 148 residences, each offering multiple levels and private terraces. The complex is interconnected by a network of pedestrian streets, bridges, and elevators. Habitat 67 represents a significant experiment in modular construction and brutalist architecture. It has received numerous architectural awards and is recognized as a historically significant monument. The complex remains a functioning private residential community.
