7 World Trade Center (7 WTC, WTC-7, or Tower 7) is an office building constructed as part of the new World Trade Center in Lower Manhattan, New York City. The tower is located on a city block bounded by Greenwich, Vesey, Washington, and Barclay Streets on the east, south, west, and north, respectively. 7 World Trade Center was developed by Larry Silverstein, who holds a ground lease for the site from the Port Authority of New York and New Jersey, and designed by Skidmore, Owings & Merrill.
The building was constructed to replace the original structure on the site, part of the original World Trade Center. The previous structure, completed in 1987, was destroyed in the September 11 attacks in 2001. Construction of the new 7 World Trade Center began in 2002 and was completed on May 23, 2006. The building is 52 stories tall (plus one underground floor), making it the 64th-tallest in New York. It is built on a smaller footprint than the original; a small park across Greenwich Street occupies space that was part of the original building's footprint.
The current building's design emphasizes safety, with a reinforced concrete core, wider stairways, and thicker fireproofing on steel columns. It also incorporates numerous green design features. The building received the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Gold certification and was part of the council's pilot program for Leadership in Energy and Environmental Design – Core and Shell Development (LEED-CS).
