The material palette was carefully chosen for minimal maintenance and graceful aging. It blends with the surrounding landscape and relies more on variation in finish and texture than on a range of different material choices. The Cor-ten paneled exterior cladding breaks down into a Cor-ten screen that runs along the landscaped entry and creates dappled shadows, mimicking those of the nearby oaks. Polished concrete entry walls flow into stairs and floors of concrete through the house and give way to a retaining wall of corduroy patterned board-formed concrete in the private bath and garden beyond.
