555 Mission Street is a 33-story, 147 m (482 ft)[A] office tower in the South of Market area of San Francisco, California.

[8] However, due to the downturn in the office market after the dot-com bust, developer Tishman Speyer froze the project waiting for economic conditions to improve.

[9] In March 2008, law firm Gibson, Dunn & Crutcher agreed to take up 60,000 sq ft (6,000 m2) of office space in the tower.

In October 2009, Intellectual Property law firm Novak Druce + Quigg moved into the 34th floor penthouse of the building.

[15] Examples of green elements within the building are low flow toilets and a reflective roof to deflect solar energy.

The park, required as part of a public space initiative by the City of San Francisco, features large outdoor sculptures by Ugo Rondinone and Jonathan Borofsky.
