About Us

We believe that designing timeless, sustainable houses should be fun and collaborative. Founded in San Francisco in 1980, Gast Architects is a service-oriented practice specializing in custom residential homes and renovations, including both contemporary solutions and the sensitive restoration and adaptation of historic properties. We offer comprehensive architectural services and we take pride in the close working relationships we develop with our clients in responding to their needs, taste, budget and schedule, while maintaining architectural design excellence. Sustainable design strategies are integral to our design process, and several on our team are experienced LEED Accredited Professionals.

Our projects range in scope from the development of large country properties and inner city whole-house renovations to more modest additions to, and remodeling of, existing housing in styles from warm modern to traditional. We enjoy, and are skilled at, working with the limitations and opportunities inherent in renovating or adding to existing structures. Our long-term relationships with contractors, craftspeople and consultants strengthen the trust and effective team communication necessary for producing superior results.

Having practiced in the Bay Area for decades, we know the local Planning and Building agencies and their staffs, and how to work with them to secure code interpretations before problems arise. We have represented our clients successfully before commissions, design review panels and appeal boards, and are adept at moving our projects through the approvals maze. Our clients have collaborated with us on projects on the California Central Coast, New York, Oregon, Montana, Wyoming, etc.

In 2019, Founding Principal David Gast initiated an ownership transition plan that was completed in 2023 with Principals Dennis Budd, Matt Williams and Eric Hartz. They now lead the firm and David continues as an advisor.

Gast Architects is a signatory to the AIA 2030 Commitment of migrating toward zero net energy and zero net carbon buildings. Since 2013, we have actively participated in the San Francisco Green Business program for sustainable business.
