Le Corbusier's five points of architecture are pilotis, the roof garden, the free plan, the horizontal ribbon window and the free facade. Published in 1927 for the Weissenhof housing exhibition in Stuttgart, they describe what becomes possible once a reinforced concrete frame, rather than masonry walls, carries a building's loads.
Most students meet the five points as a checklist next to a photo of Villa Savoye. That reading misses the real argument. Le Corbusier and his cousin Pierre Jeanneret were not proposing a style. They were pointing out that a new structural system had quietly made the old rules of house design optional, and that architects had not caught up. Read that way, the points form a chain of cause and effect you can test on your own project.
What Are Le Corbusier's Five Points of Architecture?
The five points are a short set of design principles that Le Corbusier and Pierre Jeanneret set out in a German-language brochure printed for the 1927 Deutscher Werkbund exhibition in Stuttgart. According to the Fondation Le Corbusier's page on the Weissenhof houses, this was the first time he published the main principles of his work in that form. A revised text then appeared in the first volume of his Oeuvre complète in 1929.
In their usual order, the points are:
- Pilotis: slender columns that lift the house off the ground.
- The roof garden: a flat, usable roof that replaces the pitched attic.
- The free plan: interior walls placed wherever the program needs them.
- The horizontal window: a long band of glazing across the facade.
- The free facade: an outer skin designed independently of the structure.
The French title, Les cinq points d'une architecture nouvelle, treats the points as facts that follow from construction, not as taste. The full text, summarized in the Wikipedia entry on the Five Points, presents each one as a consequence of building with a concrete skeleton.
Where the Five Points Came From: The Dom-ino Frame
The five points trace back to a drawing Le Corbusier made in 1914, the Maison Dom-ino. He developed it as a quick, standardized construction system for rebuilding homes destroyed in Flanders during the First World War. The diagram is almost nothing: three flat concrete slabs, six thin columns set back from the edge of the floor, and a stair connecting the levels.
Once columns carry the floors, walls carry only themselves: a partition can sit anywhere and a facade can be opened or glazed at will. Every one of the five points is already latent in that 1914 frame, and the 1927 text simply names them. Our explainer on how reinforced concrete works covers why slab and column can do this work.
📌 Did You Know?
The Dom-ino system was never mass-produced in the form Le Corbusier drew it. It stayed a diagram for a century, until the Architectural Association commissioned a full-scale Dom-ino, built in engineered timber by Valentin Bontjes van Beek for the 2014 Venice Architecture Biennale. The unbuilt sketch still ended up as one of the most reproduced images in twentieth-century architecture.
The Five Points One by One
Each point solves a specific problem of the load-bearing house, and each depends on the others.
1. Pilotis: Lifting the House Off the Ground
Pilotis are the columns of the frame, exposed at ground level. Le Corbusier argued that a house set directly on damp earth wasted the ground floor on cellars and service rooms. Raising the living spaces gave you dry rooms, better views and light, and a ground plane that could stay open for gardens, paths or cars.
At Villa Savoye the curve of the ground floor was set out so a car could drive in under the pilotis, turn and park, a detail the Fondation Le Corbusier's Villa Savoye entry highlights. That hovering lightness came from the structure, not from styling.
2. The Roof Garden: Giving Back the Ground
If the building occupies a patch of land, Le Corbusier reasoned, it should return that land on top. A flat concrete roof could hold soil, planting and terraces instead of an unused attic under a pitched roof. He also claimed that keeping the roof covered helped protect the concrete slab from thermal movement.
For the modern technical version, with layers and drainage, see our guide to green roof types and benefits.
3. The Free Plan: Walls Where You Need Them
In a masonry house, walls stack on top of each other floor after floor because they carry the load. The plan of the first floor is largely fixed by the plan of the ground floor. With columns doing the structural work, each floor can have a completely different layout. Curved bathroom walls, open living rooms and freestanding partitions all become routine.
The free plan is arguably the most lasting of the five points. Almost every open-plan office built since depends on the same separation of structure and enclosure.
4. The Horizontal Window: Light Across the Whole Room
The fenêtre en longueur, or ribbon window, runs the full width of a facade. Le Corbusier argued that a long horizontal opening lit a room more evenly than a tall one and framed the landscape like a panorama. Because the facade carried no load, nothing stopped the window from running from corner to corner.
This was the most contested point. From late 1923, the architect Auguste Perret, Le Corbusier's former employer, defended the tall French window, which he saw as matching the upright figure of a person standing in the room. Historian Bruno Reichlin's 1984 essay "The Pros and Cons of the Horizontal Window" in the journal Daidalos (issue 13) gives a detailed account of that quarrel and is worth reading if you want to see how a window shape became a theory of vision.
5. The Free Facade: A Skin, Not a Wall
Since the columns sit back from the edge of the slab, the outer wall becomes a thin membrane hung in front of the structure. Its openings can follow the interior's needs and the composition of the elevation rather than the position of piers. This is the direct ancestor of the curtain wall that wraps most office towers today.
💡 Pro Tip
When you analyze a five-point building for studio, draw the column grid on its own sheet first, then overlay each floor plan and each elevation. Wherever a wall or window ignores the grid, you have found the free plan or free facade at work. Juries respond far better to that layered drawing than to five labeled photos.
The Five Points at a Glance
The table below sets each point against the constraint it removed and the building where it is easiest to study.
| Point | French term | Constraint it removed | Where to study it |
|---|---|---|---|
| Pilotis | Les pilotis | House sitting on damp ground and cellars | Villa Savoye, Unité d'Habitation |
| Roof garden | Le toit-jardin | Unused attic under a pitched roof | Villa Savoye solarium, Weissenhof houses |
| Free plan | Le plan libre | Stacked load-bearing walls fixing every floor | Weissenhof semi-detached houses |
| Horizontal window | La fenêtre en longueur | Narrow openings between masonry piers | Villa Savoye upper floor |
| Free facade | La façade libre | Elevation dictated by structural walls | Villa Cook, later curtain walls |
Weissenhof 1927: Where the Points Were Launched
The five points were not written in a vacuum. They accompanied a real building exhibition, Die Wohnung (The Dwelling), organized by the Deutscher Werkbund and financed by the city of Stuttgart. The Weissenhof Museum's history of the estate notes that under the artistic direction of Ludwig Mies van der Rohe, 17 architects presented 33 designs for modern, healthy and affordable housing.
🏗️ Real-World Example
Weissenhof houses (Stuttgart, 1927): Le Corbusier and Pierre Jeanneret built a single-family house and a pair of semi-detached houses on the estate. The semi-detached pair shows thin metal columns in the recessed ground floor, a long window across the main facade and a roof garden, and it now houses the Weissenhof Museum.
Visitors could walk through the claims instead of reading them. The semi-detached houses used movable interior elements, which the Fondation describes as giving flexibility in the fittings and a great saving of space. The free plan was shown as something a family could rearrange from day to night.
Villa Savoye and the Points in Their Purest Form
The best-known application is Villa Savoye in Poissy, designed from 1928 and finished in 1931. It lifts its main floor on pilotis, wraps it in a continuous ribbon window, opens the interior around a ramp, and ends in a rooftop solarium. Our full piece on Villa Savoye as a modernist icon walks through the house room by room, so here the focus is on what it proves about the five points themselves.
Savoye shows that the points work best together: the pilotis free the ground for the car route, the free plan lets the ramp cut through every level, and the free facade lets the ribbon window run unbroken. Remove one and the others lose some logic.
It also shows the cost. The flat roofs and large glazed surfaces leaked badly and swung between hot and cold, and by around 1939 the house was barely habitable. The ideas had run ahead of 1920s waterproofing and glazing.
Criticism and Limits of the Five Points
The five points have drawn real criticism, and history exams expect you to know it.
- Climate: a sealed, glazed box on stilts suits a mild French suburb far better than a hot desert or a cold northern site. Le Corbusier himself later added the brise-soleil to shade exactly the large glass walls the free facade had made possible.
- Context: houses lifted on pilotis often ignore the street and the neighboring buildings, a failure later critics of modernism stressed.
- Universality: the points assume a single structural system works everywhere. Postmodern architects pushed back on that claim, a debate covered in our comparison of modernism vs postmodernism.
🎓 Expert Insight
"A house is a machine for living in.", Le Corbusier, Toward an Architecture (1923)
The line is usually quoted as cold functionalism, but the five points are what it looks like in practice: a house rebuilt from how it is made and used. The leaking roofs at Savoye are the reminder that a machine also has to work in the rain.
How the Five Points Shaped Later Architecture
Le Corbusier bent the points as his work changed. The clearest example is the Unité d'Habitation in Marseille, commissioned in 1945 and opened in 1952. It holds 330 apartments in 23 types, sits on massive concrete pilotis so that greenery, pedestrians and cars can pass underneath, and puts a running track, gymnasium and nursery school on the roof. The slim white columns of the 1920s had turned into heavy sculptural legs of raw concrete, which made the building an early reference for the movement described in our brutalist architecture guide.
In 2016 the World Heritage Committee, meeting in Istanbul, inscribed 17 of his projects across seven countries (France, Switzerland, Belgium, Germany, Argentina, India and Japan) as The Architectural Work of Le Corbusier. The Weissenhof houses and Villa Savoye are both part of that listing.
Outside his own work, raised ground floors, flat terraces, open plans and glass skins became so normal they rarely read as a position. If you are building a diagram set to explain these ideas on a board, ready-made architecture diagram templates can speed up the layering exercise described in the Pro Tip above.
How to Use the Five Points in a Studio Project
You do not need a white villa to use the five points. Ask them of your own scheme:
- Is my ground floor doing useful work, or could lifting part of the building open it up for public space or landscape?
- Is my roof an unused surface that could become a terrace or garden?
- Are my interior walls placed by the program, or am I stacking them out of habit?
- Do my window shapes come from the view and the light I want, or from the structure I assumed?
Answering those honestly shows a jury that you understand the relationship between structure and enclosure, which is the real content of Le Corbusier's five points of architecture.

The Bigger Picture
The five points are often taught as the beginning of modern architecture, but they read just as well as a warning. Le Corbusier saw that a new structure had changed what a house could be, and he wrote it down before most architects noticed. The next time a new material or system arrives, whether mass timber or 3D-printed concrete, the useful question is the one he asked in 1927: which old rules has this quietly made optional?
