Habitat was completed in 1967, built for the government as a part of Expo ’67. It was based on Moshe Safdie’s thesis design of 1961, which investigated the possibility of a modular, three-dimensional building system. His other goal was high-density living in a high rise urban setting that introduced features only found in a suburban garden home. Safdie envisioned a project that was a three-dimensional urban structure of modules that could be pre-fabricated and mass-produced, and that would be adaptable to any site in the world. The project was originally conceived as a multiple-use project that would include 950 residential units, as well as shops, offices, and institutions. Due to limited government funding, it was downsized to only 158 units, which are made up of a total of 354 individual modules. Modules are clustered along a spine of 3 hill-shaped structures, and they could be arranged to produce 16 different living spaces
