Designed to provide shared amenity space for a group of biotech companies in South San Francisco, this beautiful structure features a café and dining space, lounge, meeting center, fitness facility and private offices. While sustainability was a driving factor behind the overall development, and a key reason for choosing mass timber, wood added further value by creating a warm and beautiful gathering space. Cross-laminated timber (CLT) panels are supported by an intricate, elegant glulam framing system, allowing the structure to also serve as finish. Because they wanted to display the material in its purest form, designers worked to hide connections and utilities as much as possible, allowing visual attention to focus on the wood itself while creating a single architectural expression. The mass timber structure features 20-foot double cantilevered overhangs that provide outdoor seating areas as well as solar protection to minimize heat gain, which helps contribute to the project’s net-zero energy goals.

I sincerely appreciate your team’s effort to produce the best possible result for all areas of construction, factoring in the very real constraints of budget and schedule. Although there are always ways to improve—be it in design or implementation—I never felt that XL didn’t fully exhaust all options in search of the best possible solution. For that, I commend and thank you—it makes the construction process that much better (and enjoyable)!
