About this office space

Flooded with natural light, the building is a hidden gem right off of San Francisco's most central street. Designed by the iconic architectural firm Gensler, this space brings a sophisticated, yet simple, Scandinavian feel to this Market street space. This space is the former headquarters of Zendesk.

NEIGHBORHOOD Located in the heart of San Francisco’s Mid-Market corridor, the building sits at a vibrant intersection of tech innovation and historic charm. The area is a hub for startups and creative firms, with companies like Twitter and Square headquartered just a few blocks away. It's extremely well-connected, with BART and Muni stops at Civic Center and Powell Street Stations both within a 5-minute walk, making commuting from anywhere in the city or East Bay a breeze. Grab a quick bite at local favorites like The Market, Little Griddle, or Brenda’s French Soul Food, or walk a few blocks to the trendy restaurants and bars of Hayes Valley or the Mission. This spot offers the perfect blend of professional energy and cultural buzz.

PRIVACY While the desk areas are relatively open, there are dozens of meeting rooms lining the office that make finding a space for a private conversation easy. Beyond that, all of the meeting rooms are soundproofed and the whole office is filled with sound baffling to prevent the space from echoing too much.

ACCESS 24/7 access is available.
