The ceiling, designed as a hyperbolic paraboloid with sweeping curves, is the foremost sculptural element. It is really beautiful. Beauty is not the only reason for it. The unique structural characteristics of a hyperbolic paraboloid allowed for a relatively slender roof profile for the long span that was achieved, and eliminated the need for cumbersome interior columns. To keep as much space as we have, we exposed the copper plumbing and the duct work.
Copper is really pretty, and most people cover it.
We ran it around the wall so you could see it. So the engineer designed diagonal bracing which transfers the wind loads to the ground. A bridge also serves as a ramp and makes the building accessible to people with handicaps. A driveway is built on one side, but the concrete lanes extend under the house and create a contoured form that complements the roll of the land. When it's raining hard, it looks like a river.
