South San Francisco, CA


Genentech, Inc.


Perkins + Will


7 story, 250 ksf life science corporate building for 1,150 Genentech associates

The project features contemporary design aesthetic, modern materials, and a flexible interior plan. The design includes two office wings connected by a large, beautiful atrium.

As PM, TOCCI led Genentech through Highly Collaborative Project Delivery (HCPD) to deliver Genentech’s Hilltop A Building 35 at their US Headquarters location in South San Francisco. Additional teams contributing to the design and construction include Perkins+Will, Arup, and Webcore as GC.

The building is important, not just as the newest on their site but because it incorporated a series of novel design studies intended to enhance this building as well as provide a basis for enhanced design of future construction on their campus. Genentech has undertaken an aggressive program on its South San Francisco site to upgrade existing buildings and to ensure all new buildings are state-of-the-art.
