Services Offered

Walker Warner Architects provides complete architectural services for residential and corporate clients. Since its establishment in 1989 by Brooks Walker and Greg Warner, the firm has completed over 200 projects in California, Hawaii, Idaho, and Montana. Our services are tailored to the uniqueness and diversity of each client and project, while maintaining a consistent focus on design excellence and thorough project management.

Our work is best characterized by the nature of our approach instead of a specific architectural style. We approach each commission with a thoughtful process of interaction with the client and an exploration of the possibilities offered by the site. Each design begins with a study of the existing conditions, specifically: the natural features of the site, the character of any existing structures, and the context created by the surroundings. This provides a rich source of ideas that inform the entire design process and help us to create a site-specific design solution.

Our exploration is guided by the client’s needs and preferences, which frame the entire project. The goal is not simply to render the client’s ideas, but to develop an original solution that expresses the client’s vision with architectural excellence.
