The restoration of Trefethen Family Vineyards in Napa Valley focused on rebuilding and strengthening a historic winery following significant earthquake damage while preserving the character that has defined the property for generations. The design approach prioritized the retention of the building’s original architectural identity, carefully integrating modern structural improvements without altering its historic appearance. By reinforcing the existing timber framework and upgrading seismic performance, the project ensured the long-term resilience of this iconic Napa Valley winery while maintaining its authentic heritage.

Wood played a central role in both the original structure and the restoration strategy, allowing new interventions to blend seamlessly with existing materials. The structural upgrades were intentionally concealed within the building fabric, preserving the visual integrity of the historic architecture while meeting contemporary safety standards. Recognized for its sensitive approach to historic preservation and seismic rehabilitation, the project received a California Preservation Design Award. This award-winning winery restoration demonstrates how thoughtful architectural design can protect cultural landmarks, enhance earthquake resilience, and support the continued operation of one of Napa Valley’s most recognized family-owned vineyards.
