The cost would also be 4-5 billion to finish the tower which I believe they say it'll cost 5 billion (HQ2). Now that would be the dream wouldn't it. And with the Foster design.
But thats a hell of a dream.
They would also be leasing the space. I think they want to own the building(s)... where ever it winds up in, so that would eliminate WTC2 as an option. Plus IDK if the BIG or Foster design would cater to their type of work. Does Amazon really need trading floors?
