Main stair detail
The original wing is now fully dedicated to bedroom suites. A new
garage structure is folded into the Northern end of the hillside,
transitioning the grade from the main house elevation to the orchard
below.

The design of the building incorporates many passive and active
sustainable design elements. The South and North facades are widely
open to allow for passive solar heating in the winter and natural
daylight year-round, while deep overhangs provide shade in the
summer. Highly efficient spray foam insulation in the roof and wall
systems offset heat gain in the summer and retains heat in winter. The
roof orientation allows the project to integrate generous photovoltaic
and hydronic solar panel arrays. Along with a rainwater irrigation
system tied into the native landscape, this allows for the house to
provide nearly all its energy and water needs. A post-occupancy survey
has concluded that the inhabitants rarely use their heating and cooling
equipment. The winter temperatures remain comfortable with minimal
added heat, and they can passively ventilate the house in the summer
months to mostly avoid using their air conditioning system despite the
often scorching temperatures. Photovoltaic panels can produce enough
electricity for home usage and all electric vehicles. dw
