Services Offered

We create enduring architecture for inspired living.

Walker Warner Architects is a full service architectural firm specializing in custom residential and estate design, as well as winery, commercial office and recreation club design in the Western United States and Hawaii. Founded in 1989 by Brooks Walker and Greg Warner, today the firm is led by Brooks and Greg in collaboration with principals Michael McCabe and Kathy Scott.

We believe architecture should be expressive, timeless, and always in unity with the natural beauty of the site. We understand that thoughtful designs emerge through the collaborative process of listening to, learning from, and engaging with our clients. Equally important is the study of the conditions and natural features of the landscape, the character of the existing structures, and the context created by the surroundings. Through this exploration, we gain a deep understanding of our client’s desires coupled with the possibilities offered by the site, which drives the design.

Our work is informed, from concept to completion, by the highest levels of quality, integrity, and craftsmanship. It begins with a conscientious selection of appropriate materials, dedication to innovative and proven building techniques, and sustainable practices that promote environmental responsibility. Our longstanding partnerships with leading landscape architects, interior designers, builders and artisan craftspeople allow us to design with continuity, precision, and unparalleled sophistication and beauty.
