Centennial Tower, a sculptural high-rise located on a prominent site where Highway 101 curves past San Bruno Mountain, visually echoes the surrounding typography. Wrapped in a continuous, veil-like glass curtain wall that extends above the roof as a translucent parapet, the facade is a shifting canvas, reflecting the changing sky throughout the day. This curved skin is keenly tuned to the building’s solar orientation: vision glass covers the eastern exposure to maximize views, while shade-giving spandrels and horizontal screens clad much of the sunnier south side.
The program, largely dedicated to offices, also includes spaces for retail and office support, an on-site childcare facility, and a performance and conference center. Centennial Tower has proved to be a responsible member of the community. With the project’s footprint covering just eight of the building site's 20 acres, the remaining land has been reserved for conservation efforts, which include replanting a slope of San Bruno Mountain that was scarred during highway construction.
