Le Corbusier called it a "machine for living," but the Unité d'Habitation in Marseille is better understood as a small town stood on end. Built between 1947 and 1952 as postwar France scrambled to house its population, the great concrete slab at 280 Boulevard Michelet packs 337 apartments, shops, a hotel, a school, and a rooftop landscape into a single 137-metre-long block raised on massive pilotis.
The section does the work. Apartments are duplexes, interlocking like bottles in a crate, each stretching from one facade to the other so every home gets sun and a deep loggia balcony — the famous brise-soleil, whose sculptural concrete fins modulate the fierce Mediterranean light. Streets run inside the building: wide internal corridors serve as "streets in the air" every third floor. On the roof, Corbusier built a communal acropolis — a paddling pool, a running track, a gymnasium, sculptural ventilation stacks that look like a child's drawing of mountains.
It was meant as a prototype. Versions rose in Nantes, Berlin, Briey, and Firminy, and its DNA is visible in housing estates across the world, for better and worse. The imitators usually kept the concrete and dropped the generosity: the shops, the school, the rooftop. Marseille's original, damaged by fire in 2012 and meticulously restored, joined UNESCO's World Heritage list in 2016. It remains the clearest argument that density and dignity were never opposites — the failure was in copying the form while forgetting the idea.
