The Infinity or 300 Spear Street is a mixed-use residential condominium development in San Francisco, California consisting of 2 high-rise towers and 2 low-rise buildings. The complex is the first phase of a massive residential development encompassing two city blocks.[5] The Infinity development will contain four buildings enclosing 640 residential units.[6]

The two residential projects, 300 Spear and 201 Folsom, were proposed by Tishman Speyer Properties and initially designed by Heller Manus Architects.[5] The San Francisco Planning Commission was scheduled to give its vote on the two projects on June 26, 2003, but this was delayed until September.[5][7] Eventually, the two projects were given approval by the Planning Commission in spite of heavy opposition.[8] However, 300 Spear and 201 Folsom still needed approval from the San Francisco Board of Supervisors in order for the project to progress. A few months later, the Board of Supervisors gave initial approval to the projects.[9] The project was given final approval by San Francisco's Board of Supervisors on February 4, 2004.[10]
The residential complex consists of four buildings with one eight and one nine story midrises and 37 and 42 story highrise towers.[11] The highrise towers are named The Infinity I and The Infinity II. One of the towers, the Infinity I, rises 350 ft (107 m) and contain 37 floors.[2] The taller highrise, the Infinity II, rises 450 ft (137 m) [A] and contain 42 floors.[1] The 650-unit complex containing these the four buildings is bounded by Main Street to the southwest, Folsom Street to the northwest and Spear Street to the northeast.[1][2] The complex is located one block inland from the Embarcadero and the San Francisco Bay.[12] Pricing for the units range from $700k-$5 million.
300 Spear was originally designed by San Francisco's Heller Manus Architects.[13] The 820-unit complex featured a garden on top of the midrise towers and all four buildings were connected together.[13][14] Later, the developer decided to hire Arquitectonica to revamp the design of 300 Spear along with Heller Manus Architects. The four buildings of the complex were split apart and the sky gardens were gone. In addition, the complex had its color changed to a blue-green color which adapted a simplified concrete structure with curving walls of glass curtainwall and metal. The number of units was also reduced from 820 to 640 before construction of 300 Spear began.[6]
The highrise towers are planned to rise above the current buildings in between the Embarcadero waterfront and Spear Street, making the complex prominent from places like the San Francisco Bay.[5] Along with the Millennium Tower and One Rincon Hill to the west and south, respectively, they will create a new highrise neighborhood in the South of Market district.
Construction started sometime in April, 2005 when a surface parking lot was demolished to make way for the complex.[6] Midway through the excavation process, a buried 125 foot (38 m) ship was found just to the south of Spear Street.[15] The ship was found 20 feet (6 m) below street level on fill that was once a harbor.[15] The buried ship was later identified to be the 1818 whaling ship The Candace.[16]
