Promoted as a standard, easy-to-build product, The Unité d’Habitation concept spread all over the world after WWII. The first 5 units (Marseille, Firminy, Rezé, Briey and Berlin) built by Le Corbusier himself became the standard for almost all public housing project between 1950 and 1990.
Another transformation of the Unité d’Habitation was the so-called Urbanisme sur dalle (urbanisme on slabs). Instead of being raised on pillars one by one, buildings were raised in groups, with an elevated ground floor between them.
