The Unité d'habitation (French pronunciation: [ynite dabitasjɔ̃], Housing Unit) is the name of a modernist residential housing design principle developed by Le Corbusier, with the collaboration of painter-architect Nadir Afonso. The concept formed the basis of several housing developments designed by him throughout Europe with this name. The most famous of these developments is located in south Marseille.
The first and most famous of these buildings, also known as Cité radieuse (Radiant City) and, informally, as La Maison du Fada (French – Provençal, "The Nutter's House"), is located in Marseille, France, and was built between 1947 and 1952. One of Le Corbusiers's most famous works, it proved enormously influential and is often cited as the initial inspiration of the Brutalist architectural style and philosophy.
The building is constructed in béton brut (rough-cast concrete), as the hoped-for steel frame proved too expensive in light of post-War shortages. In July 2016, the Unité in Marseille and several other works by Le Corbusier were inscribed as UNESCO World Heritage Sites. It is also designated a historic monument by the French Ministry of Culture. It was damaged by fire on February 9, 2012.
