By stacking concrete “boxes” in variant geometrical configurations, Safdie was able to break the traditional form of orthogonal high rises, locating each box a step back from its immediate neighbor. This ingenious method provided each apartment with a roof garden, a constant flow of fresh air and a maximum of natural light: qualities which were unprecedented for a twelve story apartment complex. Habitat 67 thus pioneered the integration of two housing typologies—the suburban garden home and the economical high-rise apartment building.
