I believe it’s somewhere in the range of 6-8 million square feet in Ground Zero (1WTC, Freedom Tower 7WTC and depending on whether 2 and 3 WTC are built as planned. The original WTC complex had 10 million sf of space.
I’d say that with a 1 block radius you’re looking at another couple million sf of space (World Financial Center, Goldman Sachs, etc.). I don’t have an exact figure handy.
