Noted local photographer Troy Holden shared with SFist these photos of the new Twitter headquarters. The recently-opened digs at the old SF Mart feature a rooftop garden (where employees can lounge in the sun), a micro-health kitchen (so clean, stark, and anal-retentive; the stuff that gastronomic dreams are made of), a yoga studio (for crucial chakra centering), aesthetically-pleasing chat areas, arcade games (Tempest, anyone?), and the cutest reception desk that we've ever laid our eyes upon.

The social media company's move to mid-Market Street's 11-floor art deco building was a deft move by the city. San Francisco hopes it will revitalize the economically-impoverished and arguably seedy area at 10th and Market Streets. Twitter made national headlines in 2011 after the San Francisco Board of Supervisors overwhelmingly approved a somewhat controversial tax break (a convenient exemption of its 1.5 percent payroll tax on new hires at company), a move that kept the microblogging service from fleeing the city. Part of Twitter's deal with the city of San Francisco will also include, according to the SF Examiner, improved transit and new dedicated bike lanes in the area, as well as a police substation on habitually sketchy Sixth Street.

The new space will boast "80,000 square feet of retail space that will include cafes, restaurants, a health club and a local, cool grocery store," notes SF Biz Times.
