As New York City prepares to choose one of the many plans submitted by some of the world’s top architects to replace the World Trade Centers, Lisa Rochon says there’s no reason not to combine two of the plans, each of which stands out for a different, and important, reason. Daniel Libeskind’s design for the huge plaza would bring to the Ground Zero space “a carcass of stone that could become the most meditative public space in the world.” And the Think team’s design for two huge latticework towers could reach “beyond the security of a nation to a new security in our minds — to an architecture that invites intellectual curiosity and the possibilities for cultural humility.”
