For over 20 years, we have been working to create architecturally innovative and technologically superior commercial and residential buildings in both Napa and Sonoma counties. We provide architectural and design consultation to some distinguished business and land owners. Among them are Dario Sattui (Castello di Amorosa), Chuck McMinn (Vineyard 29), Thomas Keller (The French Laundry), Clarke Swanson (Swanson Vineyards), Hugh Davies (Schramsberg Vineyards), Jayson Pahlmeyer (Pahlmeyer Wines) and Ken and Rebecca Laird (Laird Family Estate).
After long time association as architects for Lail Design Group in St. Helena, we formed osborn siegert architecture [os-arch] in the spring of 2011. Together we have a partnership with the common goal of offering clients clear, objective, and thoughtful design alternatives. We offer both the skills of experienced architectural professionals and the leadership to facilitate your projects.
