Returning to the Le Corbusier's third point on new architecture, the plan libre, the interior of the Villa Savoye is fundamentally based on the idea of the column and the uninterrupted floor slab. Slender, white pi/oti (columns) support the cube-like upper levels of the house and create a grid of supports that allow the architect to freely place the interior walls. 87 Large panes of glass span from floor to ceiling and blur the distinction between the exterior courtyard and the interior spaces. Le Corbusier dictated every aspect of the interior design, including the selection and placement of the furniture, wall colors, and in some cases the location and works of the client's art collection.
