"This was a way to mimic the changing patterns in the natural environment," he says. "Similarly, there is no ordering device, such as a grid or module. The structure has evolved from the functions required within the house and the need for sun and natural light."
Choate says the house, which was designed around three mature cedar trees, needed to have more of the feel of a rocky outcrop, than a man-made object. Within these parameters, however, there is a symmetry to the formal areas.
"Within the asymmetic layout of the house, these rooms provide a focus and help define the sub-space within the larger, flowing space. This symmetry at the center is also typical of nature."
The spacious feel of the interior is enhanced by the open-plan layout and cut-outs in the concrete formwork.
"It was important to be able to see through to other rooms," says Choate. "Rather than providing a series of boxes to enclose people, the walls and planes are arranged to create spaces for people to flow through and inhabit. For this reason, also, the outer corners of rooms are chopped off and glazed, avoiding a boxed-in feel."
In keeping with the minimalist aesthetic and the desire to "let the architecture do the talking", the raw materials have largely been left untreated and undecorated. However, to balance the cool look of the gray concrete and steel, reclaimed Douglas fir beams are used extensively.
"These beams and columns weave their way through the house like a thread that ties everything together. They provide a warm contrast to the other materials," says Choate.
In addition to raw concrete, there are walls and ceilings of raw, off-white plaster. The ceiling above the kitchen was tinted a dark gray to help define the space within the open-plan area. Here, cherry cabinetry matches the warm wood tones of the fir beams and the shelving planks.
