Habitat 67
Habitat 67, an experiment in apartment living, became the permanent symbol of Expo 67 after it closed. It was Canadian architect Moshe Safdie's experiment to make a fundamentally better and cheaper housing for the masses. He attempted to make a revolution in the way homes were built - by the industrialization of the building process; essentially factory mass production. He felt that it was more efficient to make buildings in factories and deliver them prefabricated to the site.
Safdie was dissatisfied with both suburbia, which destroyed open space surrounding cities and cut off people's enjoyment of the amenities of city life, and with the high-rise apartment block, which concentrated people on less land. Apartments generally were too small for growing families, and lacked both privacy and outdoor space. He was convinced the later were inadequate as family housing.
He planned Habitat with the goal to find a way to put a great many people on a small space, yet provide them with at least some of the pleasures of a private home. He wanted to build a city in the sky, a 3- D city and his city would contain 1000 housing units, with shops and even a school. What he proposed was an experiment, not just in housing, but in community life.
But between 1964 and 1966 when construction started, it was downsized to only 158 dwelling units, without shops and a school. What started out as a plan for a small city, instead became a hugely expensive apartment building. Worse, while it was on Expo 67 grounds, when Expo 67 closed, it would be some distance from the rest of Montreal's business and housing neighborhoods.
As Habitat was designed, it resembled a curious concrete mountain of dwelling places, strikingly modern, yet reminiscent of a Taos Indian pueblo village, or an Italian hill town. Its units were built on the ground, then hoisted by crane into place five, six or more stories above the ground.
