A deadlock between the Port Authority and private developer Larry Silverstein appears to have put a stop to rebuilding on the Ground Zero site.

The original design for the site was planned by architect Daniel Libeskind and shows one dominant tower, with three others curving around it and a central memorial to the 9/11 victims.

Building has already begun on the site where owner of the Twin Towers, Larry Silverstein is overseeing construction of the smallest fourth tower, designed by Japanese architect Fumihiko Maki.

However the Port Authority which controls the site is concerned that due to the current economic climate, they will not be able to fill the office space created by the planned four new towers and has put forward new blueprints showing towers two and three drastically reduced in size from over 70 storeys each to just 3 or 4.

The New York Daily Times has blasted the plans and describes tower two as looking like a “glorified, prettied-up stump” and tower three as “another stumpy building.” The new design would also leave large empty spaces around the site.

New York mayor, Michael Bloomberg has invited both the Port Authority and Larry Silverstein to an emergency summit meeting this week to try and finalise the plans for the site.
