How Le Corbusier's Five Points of Architecture Modernized Urban Housing Design
Quick fact
Le Corbusier's Five Points, published in 1926, were fully realized in his Villa Savoye (1928-31), which essentially became a manifesto in concrete-and-glass that influenced thousands of public housing projects worldwide.
Why this is interesting
You've seen thousands of apartment blocks with open ground floors and ribbon windows, but have you ever wondered why they look so similar? The answer lies in a short list of design rules written nearly a century ago.

Understanding How Le Corbusier's Five Points of Architecture Modernized Urban Housing Design
Imagine a traditional house as a box of load-bearing walls: the walls hold up the floors, so openings are limited and the interior is divided into fixed rooms. Le Corbusier proposed turning this box upside down, using a reinforced-concrete skeleton (posts and slabs) that carries all the weight. This small change unlocks an enormous freedom. The 'pilotis' are the slender columns that raise the building off the ground, freeing the street-level for cars, gardens, or passage. Because the walls no longer support anything, the interior can be arranged in an open 'free plan', and the facade can be a thin membrane with windows wherever you want—the 'free facade'. Instead of vertical windows, you run a long 'horizontal window' along the facade to let in even light. Finally, the flat roof becomes a 'roof garden', turning the space you lost at ground level into a green terrace. These five ideas work together as a system: each one relies on the structural logic of the frame.
A deeper explanation
The mechanism that makes the Five Points work is the shift from masonry construction to a reinforced-concrete frame. This is what engineers call a 'domino' frame, named after a schematic domino by Le Corbusier. Because the columns are set back from the facade and the floor slabs are flat, the entire building can be organized without traditional walls. The result is a total flexibility of space: you can divide a floor into different rooms with partitions that can be moved, or leave it open-plan. This flexibility directly modernized urban housing because it allowed for efficient, repeatable floor plates, uniform window strips, and the stacking of identical dwellings into high-density towers. The pilotis also became an urban device: they lifted housing above the street, allowing a continuous flow of traffic and greenery underneath, which Le Corbusier later scaled up in his plans for 'vertical garden cities'. Thus, the Five Points were not just a style; they were a structural revolution that made the modern housing block possible, shaping the way cities around the world were rebuilt after World War II.
