Who We Are
Luxury Home Transformation, Built on Expertise & Integrity
At LEFF Design Build, we don’t just build homes—we craft architecturally stunning spaces that redefine luxury, function, and longevity. Since 1978, we have been Sonoma and Napa County’s premier design-build firm, creating bespoke, high-performance homes that blend beauty, craftsmanship, and sustainability.
Our fully integrated design-build approach ensures that every project is seamless from concept to completion—with one team, one vision, and one point of accountability.
