Charged with creating three major commercial skyscrapers that will each integrate seamlessly into the overall master plan for the WTC site, a select group of the world's most accomplished architectural and engineering firms has been assembled to form a single WTC Design Team. Each firm has a vital function in the design process.
A division of Silverstein Properties, Inc. created to oversee the company's rebuilding efforts at the WTC site. Led by Larry Silverstein, the team on 7 WTC.
Foster + Partners, headed by Norman Foster, is the designer for Tower 2 of the WTC site, to be located at 200 Greenwich Street. The tallest of the Greenwich Street towers, this soaring structure topped by a pinnacle of diamond-shaped roofs will be the second-tallest building at the site and in New York, after the Freedom Tower.
Rogers Stirk Harbour + Partners is the designer for Tower 3, to be located at 175 Greenwich Street at the WTC site. Headed by U.K. architect Richard Rogers, the firm has designed a 1,155-foot-tower with prominent setbacks and an exposed exterior structural diagrid system.
