LET'S DESIGN WITH PERSPECTIVE, TOGETHER.
Building a home is an investment in time and money, and the success of your project is tied directly to the team you trust to work with.
Over the last two decades, we’ve built a network of trusted local vendors, builders, and contractors — relationships and referrals that give us a distinct advantage and efficiency over larger firms.
Where most architecture and design firms stop, we keep going to ensure you’re supported throughout the entire design and construction process. We advocate for your vision, always, from the first concept to the last detail.
ABOUT US
We are Zeitgeist, a full-service architecture and interior
design firm specializing in custom, upscale homes.
As an architecture and interior design team, we address your project in a comprehensive way. Our collective training and backgrounds result in a fully integrated design, uniting the aesthetics of the interior and exterior, from the flow of a space to the feel of the hardware. We also integrate your vision, lifestyle, functional needs, and work patterns -- and the result is a smart, sophisticated, comprehensive solution that will fit you like your favorite pair of jeans.
We strive to not only create beautiful, refined designs, but also to provide an enjoyable, expedient, and cost-effective process. We are highly experienced in guiding our clients through every step of the construction process, from designing and permitting to furnishing custom residences.
We opened our doors in 2001, and over the years we are proud to have taken part in hundreds of projects in Sonoma County, the San Francisco Bay Area, and across California. As a locally-owned business, we live and work alongside you in Santa Rosa, California.
Wichmann Zeitgeist Sonoma, Inc., is a CA S Corporation.

EFRAIM WICHMANN
PRINCIPAL, DESIGNER
Temple University, Philadelphia: Bachelor of Architecture
Efraim grew up in Swabia in southwestern Germany. He moved to the United States in 1990. His father, being an architect and exposing him to European design principles, has served as a solid foundation for his creativity. Focusing on high-end residences, Efraim is hands-on and accessible throughout the design process. He is an innovative space-maker, always challenging conventions and bringing fresh, uncompromising design to his projects. When not at work, he enjoys spending time with his children, doing road trips with Jessica on their classic Ducati, and sailing in exotic places. Efraim is a CASA volunteer (Court-Appointed Special Advocate) and a fierce champion for foster youth. A percentage of Zeitgeist Sonoma’s profits are donated directly to support this cause.
