Two plans which would create the world's tallest structure have been chosen as finalists for the World Trade Center site in New York. Both designs feature structures higher than the world's tallest buildings, the Petronas Twin Towers. The two firms behind the plans are Libeskind, which designed Berlin's Jewish Museum, and the international Think team, led by New York-based architects Rafael Vinoly and Frederic Schwartz. The finalists were announced on Tuesday, with the final choice expected sometime this month. Nine proposals for redeveloping the former site of the twin towers were unveiled last December, after previous proposals were rejected as being unimaginative.
