Engineering News-Record (ENR) has selected Avia Labs as the winner in the category for Best Office/Retail/Mixed-Use in the 2026 Regional Best Projects competition in the Northern California region. Projects were evaluated on the ability of the project team to overcome challenges, their contribution to the industry and community, safety and construction, and design quality.
Located in Millbrae, California, Avia Labs offers six stories and 315,000 square feet of state-of-the-art laboratory and office space for leading biotechnology companies and academic research institutions.
Adjacent to BART and Caltrain stations, San Francisco International Airport, and three major highways, Avia Labs establishes a new convergence point for life science research. While the site is highly accessible, its proximity to multiple modes of transportation presented several design challenges. The six-story zero-lot line design maximizes square footage while staying under the FAA height limit.
The building’s façade is articulated with glass fiber reinforced concrete (GFRC) panels and acoustically glazed units, which mitigating sound and vibration in a high-traffic area while allowing daylight to penetrate the deep floorplates.
