Award Winning Boutique Residential Design Firm



Heydt Designs is a boutique residential design firm located in Marin County, California offering comprehensive residential design services and construction documents for high-end, detailed, and thoughtful homes throughout the Bay Area.

Principal Leigha Heydt has been in the home improvement industry since 1993 when she renovated a 1922 Tudor in the historic Rockridge District of Oakland, California. Over the years, she owned and operated a landscape design/build business as well as a residential design/build construction company serving clients in the San Francisco Bay Area. In 2004 she transitioned into design services exclusively.

Leigha is licensed by the State of California as a Class "B" General Building Contractor. Currently she offers start-to-finish design services for high-end homes throughout the Bay Area including complete construction documents for new homes through construction observation.

Leigha's design philosophy can be summed up in the following words: Lightness, Cleanliness, Quality, Simplicity, Detail, and Connection to Nature. Connecting indoor environments to exterior spaces is a particular passion for her.

Leigha lives with her family in the coastal hills of Muir Beach, California. She enjoys nature, travel, aesthetics, learning, and exploring. She loves working with fun families and individuals; assisting them in turning their visions and dreams into tangible realities.


As a high end interior designer I've had the honor to collaborate with Leigha on several projects including one our most popular projects in Mill Valley where she did the Architecture and we did the Interiors. It has regularly been one of Houzz's most popular projects for almost 10 years now!! Leigha is a total pro, she knows the construction side as well and has a perfect eye for detail, finishes etc. She's also a joy to work with and helps make clients happy! I cant recommend her enough!
