Leigha Heydt graduated with Honors from the University of California at Berkeley in 1994 with a Bachelor of Arts degree in Rhetoric and a Minor in Conservation and Resource Studies. After graduating, she co-owned and operated a Residential Design-Build Landscape and Construction firm. In 2003 she obtained her Class B General Contractor’s license from the State of California, and launched Heydt Designs in 2004.

Leigha enjoys the process of collaborating with fun clients, and their teams, to achieve their design goals and manifest their dreams. She lives with her family in the coastal hills of Muir Beach, California, enjoying the outdoors, traveling, cooking, entertaining, and exploring.


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!
