The floating effect is emphasized through a series of sliding glass doors that open up to cover walkways or patios. The way in which Neutra designed the Kaufmann House was such that when the sliding glass doors were opened the differentiation of interior and exterior was blurred as if it was a sinuous space.

The flow from interior to exterior space is not simply a spatial condition rather it is an issue of materiality that creates the sinuous experience. The glass and steel make the house light, airy, and open, but it is the use of stone that solidifies the houses contextual relationship. The light colored, dry set stone, what Neutra calls “Utah buff,” brings out the qualities of the glass and steel, but it also blends into the earthy tones of the surrounding landscape of the stone, mountains, and trees.
