The taller tower, located at 50 First Street, is expected to rise 905 feet (276 m) and contain 34 stories (1,010,000 square feet (94,000 m2)) of office space below 19 floors with approximately 111 residential units. The base of the tower includes a six-story tall, outdoor "urban room" of public open space. The tower will feature diagonal, exterior bracing and taper towards the top, reminiscent of the John Hancock Center in Chicago. If completed as proposed, the 905-foot (276 m) tower would become San Francisco's second-tallest building after Salesforce Tower, surpassing the long time record-holder, the Transamerica Pyramid.
The shorter tower, along Mission Street, is planned to climb 605 feet (184 m) and will contain the 169-room Waldorf Astoria San Francisco hotel on the first 21 floors and approximately 154 residential units on the upper 33 floors.
The parcels around 50 First Street were upzoned as part of the Transit Center District Plan approved in 2012 in conjunction with the new Transbay Transit Center. The parcels were originally assembled by developer David Choo and a plan was floated in 2007 for towers as tall as 1,200 feet (370 m) designed by Renzo Piano. Choo was eventually forced to sell the property during the 2008 financial crisis.
In 2013, TMG Partners and Northwood Investors acquired the property out of bankruptcy court for US$122 million. TMG and Northwood hired Foster + Partners and Heller Manus Architects to re-design the project. In 2015, Beijing-based Oceanwide Holdings acquired the property for US$296 million. A groundbreaking ceremony for the buildings was held on December 8, 2016.
