One Rincon Hill is a 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 planned to reach a height 495 feet (151 m) with 45 stories.[A][10] The other tower, One Rincon Hill South Tower, is 60 stories and stands 641 feet (195 m) tall.[A][B] The South Tower contains a number of unique elements, such as high-speed elevators 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 blocked views, pricing, and the architectural style of the One Rincon Hill complex.[11]
