World Trade Center (WTC) developer Larry A. Silverstein on Thursday unveiled the cutting-edge designs for three towers to be built at the site, days before the sixth anniversary of the Sept. 11 attacks.
"From a design perspective, each of the three towers is distinct. Yet all three are architecturally compatible and work together seamlessly," said Silverstein.
He said the buildings will be environmentally friendly and will use the latest technology and safety innovations.
Construction on the three towers will begin next year.
Their designs pay respect to the Freedom Tower, the first of the total four towers to be built at the site, and the memorial where people can mourn the deaths of the thousands who died in the 2001 terror attacks.
Tower Two, a 79-story skyscraper, will rise to 1,270 feet and be topped by an 80-foot antenna. Its sparkling glazed crystalline form and diamond shaped summit create a bold addition to the New York skyline. It is set for completion in 2013.
Tower Three and Tower Four, which will rise to 71 stories and 64 stories respectively, are set to be completed in 2012.
The three buildings were designed respectively by British architects Lord Norman Foster and Lord Richard Rogers and Japanese architect Fumihiko Maki.
Foster's three-story lobby will showcase large artworks. Rogers' tower will feature a 35-foot-high media installation showing videos that can be viewed through the glass.
On the other side, Maki's lobby features a polished black granite wall that would reflect the two memorial pools, and the walls around the elevator will be made of the same white oak trees that will stand in the memorial plaza.
The completed towers, which will occupy nearly 16 acres of Lower Manhattan, will feature millions of square feet of office space and half a million square feet of retail space.
The total price tag for rebuilding the site could be around 16 billion U.S. dollars.
The Freedom Tower, the memorial and the wing-shaped transit terminal by Spanish architect Santiago Calatrava are already under construction. Steel for that 1,776-foot tower has nearly reached street level, and the building is set to open in 2011.
