What if we could work in a park?

When it comes to workspace, the primary tools to increase innovation and productivity are state-of-the-art mechanical systems, air filtration, sunlight exposure, greenery, vertical transportation, and a host of others. But none, are as important as allowing occupants of the building to be surrounded by nature. At 270 Brannan, the intent was clear from the onset, to create a workspace that has a better relationship with nature and thus a more fruitful place to work.

Peter Pfau’s Vision
Founder and Principal, Pfau Long Architects

San Francisco and the Bay Area’s extraordinary climate is envied globally. The ability to work, play, eat, and exercise outdoors for much of the year is something inhabitants of only a few cities can experience. With this in mind, it's remarkable how few building​s in San Francisco seek to blur the lines between nature and the workplace. Today, the biophilic design will bring over 10,000 RSF of outdoor green space to the workplace.

 

Stadium, 5-star, dive bar or anything in-between
