A welcoming presence

350 Mission is a multi-tenant office tower that challenges conventions through its high-performance environmental design, workplace infrastructure and engagement of the public realm at street level.

The architecture offers an exceptional contribution to city life by replacing the traditional corporate lobby with a 50-foot-high public “urban living room” that occupies the entire ground floor and includes a mezzanine dining and lounge level, connected by an amphitheater stair. Ninety linear feet of folding glass panels erase the boundary between the street and this space. A monumental digital art wall, with an installation by artist Refik Anadol, animates and extends the life of the interiors to the street.

Considering that it clocks in at just 30 stories, the office tower at Mission and Fremont streets may be San Francisco’s most ambitious new high-rise.

Flexible and efficient

The building is LEED Platinum-certified. Its environmental advances include rainwater harvesting, graywater recycling, and a structural design that provides 20 percent more interior ceiling height and natural light through the use of a long span, ultra-thin concrete flat slab super structure rather than a conventional steel frame.

Direct outside air is introduced through a raised floor plenum above each floor slab providing uniform comfort with minimal energy expenditure. This integrated system provides a highly flexible interior space adaptable to rapidly evolving 21st-century workplace and an even broader resiliency, offering a direct means of conversion between office, residential, and other typologies.


Finding daylight

350 Mission is set within a forest of taller buildings defining San Francisco’s Transbay Transit Center neighborhood, which block direct sunlight to its facade. In response, the exterior wall is floor-to-ceiling glass, maximizing access to ambient light inside. Constant shade from neighboring tall buildings also meant the traditional use of sun to animate the facade with the movement of light and shadow was not possible.

To enliven the architecture in this shaded setting, the facade’s full-height glass panels alternately tip upward toward the sky and downward toward the ground to create an animated, woven texture that reflects contrasting sky brightness and street movement. This facade, with its innovative aesthetic and high-performance environmental design, coupled with the generosity of the publicly spirited street-level design, gives 350 Mission a distinct urban presence in the neighborhood.
