One Rincon Hill is an upscale residential complex on the apex of Rincon Hill in San Francisco, California, United States. The complex, designed by Solomon, Cordwell, Buenz and Associates and developed by Urban West Associates, consists of two skyscrapers that share a common townhouse podium. One tower, One Rincon Hill North Tower, is under construction as of 2013 and will reach a height of 541 feet (165 m) with 50 stories. The other tower, One Rincon Hill South Tower, is 60 stories and stands 641 feet (195 m) tall. The South Tower contains high-speed elevators with special features for moving residents effectively, and a large water tank designed to help the skyscraper withstand strong winds and earthquakes. Both skyscrapers and the townhomes contain a total of 709 residential units.
The building site, located right next to the western approach of the San Francisco – Oakland Bay Bridge, formerly contained a clock tower. The clock tower was demolished shortly after the city approved the One Rincon Hill project. Construction of the townhomes and the South Tower lasted from 2005 to 2008, but was stopped for brief periods of time due to seismic concerns and a construction accident. As the South Tower neared completion, it generated controversy concerning view encroachment, high pricing, and architectural style.

One Rincon Phase II is the second tower of the One Rincon Hill development and will complete this landmark San Francisco project. Webcor performed the concrete on Phase I and was selected to provide general contractor services for the entire Phase II project. The second tower is 52 stories and includes 299 residential units over approximately 505,000 gross square feet. Amenities include a fitness center and a sky lounge on the top floor. The structure consists of a concrete core and large steel reinforced concrete columns called outriggers. The core is attached to the outrigger columns by steel buckling restrained braces (BRB’s) that are designed to transfer loads in a seismic event. The roof levels of the building include tuned mass damper tanks containing 50,000 gallons of water to counter any building movement.
