SAN FRANCISCO—Flexible workspace provider Breather has signed a lease for three floors at 565 Commercial St., a former PG&E substation listed on the National Register of Historic Places located in the Financial District. The company will offer the building’s 11,817 square feet of zoned office space to businesses looking to rent flexible and private workspaces.

“San Francisco’s flexible space market is predicted to triple in the next five years, an opportunity Breather is poised to capture by providing businesses with private, flexible workspaces that solve the major pain points of co-working,” said Jenny Hahn, Breather’s director of Real Estate. “565 Commercial St. is the blueprint for Breather’s next-generation spaces, which harness research-based design to support productivity, focus and activity-based work.”

565 Commercial St., which is Breather’s largest workspace location in San Francisco, sits above the building’s ground-floor restaurant space occupied by Leo’s Oyster Bar. The configurable floor plans can be rented as three separate full-floor offices of almost 4,000 square feet each or multiple floors taken by a single tenant.

Breather, which operates 70 fully serviced workspaces in San Francisco and more than 500 spaces globally, will rent out the spaces on a month-to-month basis, allowing tenants to scale office space as businesses grow. Tenants at this building can also access Breather’s other locations in the Bay Area on-demand for hourly or daily use.

“Finding office space is a distraction and a huge cash burn for startups and growth-stage companies,” said Bryan Murphy, Breather’s CEO. “Our flexible private offices and network of on-demand workspaces are helping businesses with dynamic headcount to maximize their capital efficiency, and improve productivity and employee retention.”
