A remarkable concrete dwelling cut into a rocky ridge of the Arizona desert has won acclaim from many architects. The structure is composed of an exposed concrete wall system with perimeter concrete beams. All the walls have exposed aggregate surfaces. Most floors are concrete slab on grade, either carpeted or covered in native Arizona flagstone. Local cement and aggregate were used to produce the relatively warm concrete color.
The house was built of 3500-psi concrete, and a 5000-psi mix was used for the driveway ramp. Concrete for the walls was a locally standard exposed aggregate mix containing 65% dry-rodded coarse aggregate (per unit volume of concrete). A surface retarder applied to the wall forms was used to facilitate exposure of the aggregate by sandblasting. The most unusual concrete feature of the home is the unique driveway system, in which the architect focused on its cantilevered concrete ramp.
