This extensive phased remodel and addition to a ranch-style home on the eastern edge of Napa Valley curves dramatically up towards the southern sky and views of nearby Mt. George while opening up and connecting to the surrounding landscape. The curved roof building sections—working around and amongst existing trees—repeat on different levels, wrapping a series of outdoor spaces and culminating in a remote studio workspace near the creek at the bottom of the property.

The view between the pieces shifts, refocusing the distant views and levels of privacy. The simple, almost Japanese aesthetic is balanced by a rich but subtle material palette of PISE coated straw-bale, stained concrete, stained wood siding, and hand-peeled cedar columns.

The high curved roofs feature a radiant barrier beneath a ventilated cavity for protection against high summer daytime temperatures. Both the renovated and added spaces are carefully oriented and shaded—with substantial overhangs and light shelves—for optimum passive solar heating and cooling.
