The new Pinterest headquarters in San Francisco is inspired by the redesign of the company's web platform — clean, simple, intuitive. The building is a four story concrete structure that originally housed a John Deer factory in San Francisco’s Central SOMA district.

The program is organized as porous, concentric layers around a large, central interconnecting atrium and stair. The program includes: large “town hall” all-hands /dining space on the ground floor, expansive open workspace on the upper three floors, both formal and informal meeting rooms, team rooms, lounge spaces, quiet room, maker lab, coffee bar, and design studio. A key aspect of the design involved extending the existing two story atrium to the ground floor, creating a central void at the building’s center that visually connects all four floors— within which lives the main communication stair. 
The stair acts as the central organizing figure of the workspace. Awash in daylight, the stair — referred to as the Knitting Stair in reference to the company’s collaborative ethos represented by the act and product of knitting — takes the form of a perforated steel-clad volume that doubles back and intersects itself at its midpoint. The intersection allows people unexpected glimpses between two flights of people moving up and down within the stair’s interior volume. A multitude of similar spatial intersections join the individual meeting room volumes with surrounding open workspace on the upper floors.
