7 World Trade Center
7 World Trade Center (WTC) marks the gateway to the new WTC and heralds the spirit of redevelopment and renewal in downtown Manhattan. Opened in May 2006, the rebuilt 52-story, 1.7-million-square-foot office tower is now fully leased, with a tenant directory that includes Moody's Corporation, WestLB, New York Academy of Sciences, Wilmer Hale, Ameriprise Financial, BMI, Silverstein Properties, and Mansueto Ventures, publisher of Fast Company and Inc. magazines. The building is developed, owned, and managed by Silverstein Properties.
Located at 250 Greenwich Street and bound by Greenwich, Vesey, Washington, and Barclay Streets, the 741-foot-tall structure contains 42 column-free, tenant floors, each averaging 40,000 square feet and starting on the 10th floor. The lower floors of 7 WTC are dedicated to building mechanical facilities and a Con Edison substation that supplies electrical service to downtown Manhattan.
Sustainable design is among the most important initiatives at 7 WTC. The U.S. Green Building Council, which has developed the nation's only common standard of measurement for a "green" building, certified the tower at gold status for core and shell development under its Leadership in Energy and Environmental Design (LEED)-rating system, making it the first green commercial office building in New York City.
Artist and MacArthur Fellow James Carpenter worked with David Childs and the SOM team to design the exterior podium wall and its lighting. Inside, the building lobby features a site-specific installation by acclaimed conceptual artist Jenny Holzer. The work is an animated-text installation of prose and poetry that scrolls across a glowing 65-foot-wide, 14-foot-high glass wall behind the reception desk.
The triangular park at 7 WTC, situated between the now-extended Greenwich Street and West Broadway, creates public open space and provides light and views in a previously congested area. The park, designed by landscape architect Ken Smith, consists of a central open plaza with a fountain and flanking groves of trees and shrubs. At the center of the park, solid marble benches surround a 30-foot-wide fountain with jets of water. Featured in the fountain area is a sculpture by renowned artist Jeff Koons, Balloon Flower (Red).
Among its many building enhancements, 7 WTC has a reinforced concrete core and a steel superstructure. Safety systems exceed New York City building code and Port Authority of New York and New Jersey requirements and are expected to form the basis for future high-rise building codes. Tishman Construction Corporation served as construction manager for 7 WTC.
