The Spiral Stair

Its shape was inspired by nature's most perfect spiral. This is not only a way to move between floors — it is the building's artwork, a sculpture in its own right.

A spiral staircase is the rare piece of architecture that is also furniture, also art. Its shape — borrowed from the nautilus, the most efficient spiral in nature — takes the smallest footprint in the room while making the biggest gesture.

And because the curve is graceful, even a hard material softens: steel, iron, concrete, wood — turned into a spiral, each one brings a kind of tenderness to the space. Build the rest of the hall quietly and let the stair speak.
