The Tilt-Up, Transformed

Assembly at North First started out as one of Silicon Valley's ubiquitous office parks of featureless concrete tilt-up buildings. A new, envelope-pushing design by Gensler has turned this former LAM Research campus into what San Francisco Magazine calls "an idyllic cluster of shedlike structures that recall Santa Clara Valley's agrarian roots."

Wood and steel construction bring sawtooth roofs and clerestory windows to the original concrete building, giving a nod to the area’s agricultural past while preserving the original form. New large windows flood the spaces with natural light, and high ceilings contribute to a sense of volume and air.

The substantial interior spaces can house entire teams on a single floor, fostering collaboration and cross-pollination.

The outdoor kitchen, dining, and seating areas, fire and barbeque pits, and wood-burning pizza oven—surrounded by native and drought-tolerant landscaping—set the stage for a more casual exchange of ideas.

Assembly at North First Street is pending LEED Gold certification for its core and shell development.
