WTC: The Memorial And The Mall

"Commerce is a given at the rebuilt site, and there's nothing wrong with that: the World Trade Center was a fundamentally commercial entity...But it will be hard to keep the retail from overwhelming the rest of the design, especially when you consider that planners are being asked to accommodate about 40 percent more retail than existed before 9/11—and in a space that, with several acres set aside for a memorial, will be up to 40 percent smaller."
