Which item is NOT considered one of Le Corbusier's five points of new architecture?

• A. Curtain wall
• B. Pilotis
• C. Free plan
• D. Ribbon windows

Answer: (A)

Le Corbusier's five points describe a way to liberate the building from its load-bearing walls, allowing the interior to be reorganized and the exterior to express a new clarity. The ideas include using pilotis to lift the structure off the ground, a free plan enabled by those columns, a free façade where the outside skin is not structurally bound, ribbon windows that run horizontally across the façade, and a roof garden to reclaim space on the top. Curtain wall is not one of these five. It refers to a non-structural exterior skin used in later modern architecture, whereas the five points specifically name pilotis, free plan, free façade, ribbon windows, and roof garden.
