NEW YORK, Sept. 7 (Xinhua) -- New Yorkers get a glimpse of how Lower Manhattan Looks like in 2012 as the designs for three new buildings at the World Trade Center site were unveiled Thursday.

    Governor George Pataki joined architects and developer Larry Silverstein Thursday to unveil designs for World Trade Center buildings No. 2 through No. 4. The trio of towers are slated for the eastern portion of the WTC site and next to the 1,776-foot Freedom Tower. They will be part of a transit hub and face the memorial for the Sept. 11 terrorist attacks.

    The towers have wider floors for financial trading and plans for shops that would replace the former mall at the trade center. The new towers would return more than 6 million of the 10 million square feet destroyed on Sept.11. Construction is to begin in 2007or 2008 and expected to be finished by 2012.

    The largest of the planned buildings is a 78-story tower with a roof sliced into four diamond shapes and pointing lights toward the former twin towers.

    Another 71-story tower with crisscrossing beams up and down the sides, a 180-foot-tall lobby and five trading floors.

    A 61-story tower would be the first to be built. It would have a restaurant and bar with panoramic views of the memorial.

    The Freedom Tower, the memorial and a permanent transit hub are currently under construction.

    Last December, Silverstein commissioned Lord Norman Foster of England to design Tower 2. In April, he commissioned designs from two more architects. Lord Richard Rogers, also of England, designed Tower 3. Tower 4 was designed by Fumihiko Maki of Japan. Representatives from all three design teams collaborated on the project. Enditem
