Architect: THINK Design: Shigeru Ban, Frederic Schwartz, Ken Smith, Rafael Viñoly
This consortium of architects, who called themselves THINK Design, created three different designs for the competition. One, called 'The Great Room," consisted of enclosing 13 acres of Ground Zero under a 30-story glass roof. The footprints of the twin towers would be under the roof and encased by glass cylinders that would demarcate the memorial site.
