Two years after entering the New York market, Silicon Valley firm Fenwick & West plans to move to long-term office space in the Flatiron District—a rare move for an Am Law 100 firm to Manhattan’s Midtown south.

Fenwick & West, which has been subletting space from Ropes & Gray in Midtown since 2016, will move this fall to 902 Broadway under a 10-year lease. The firm is more than doubling its space to 36,400 square feet across two floors at the Broadway office.
