Nestled in the beautiful Sonoma County, the Knights Valley Residence is a unique architectural masterpiece that was inspired by Charles Keeler’s definition of California architecture as "landscape design with occasional rooms in case of rain." Built by William Turnbull and Mary Griffin as their own family retreat, the house is an exploration of how minimally they could impact the site.

At only 640 square feet, the Knights Valley Residence is deceptively simple. The house combines architecture and landscape to create large rooms out-of-doors. The house and well buildings are sited on a bench, the only flat area in the vineyard. They frame a lawn that opens out to an oak grove with a dramatic view of Mt. St. Helena.



One of the most striking features of the Knights Valley Residence is the use of sustainable materials and construction practices. The house is heated by a wood-burning stove and uses Douglas fir milled from wind-topped trees on the property. This use of locally sourced materials reduces waste and environmental impact, making the Knights Valley Residence a model for eco-conscious design.

The Knights Valley Residence is a perfect example of how architecture and landscape can come together to create a space that is both beautiful and functional. The house is a true work of art, and its design is both simple and elegant. It is a retreat for those seeking peace and tranquility, and its use of sustainable materials and construction practices makes it a model for eco-conscious design.

Overall, the Knights Valley Residence is a testament to the beauty of California architecture and the possibilities of sustainable design. Its unique design, use of sustainable materials, and stunning location make it a truly inspiring space. Whether used as a retreat or a family home, the Knights Valley Residence is a perfect example of how architecture and landscape can come together to create a space that is both functional and beautiful.
