Well I suppose that the elevator load would be the biggest problem. If you had even a free observation deck, it would probably suffer from huge traffic loads. I would like to see a mall (or some retail floor) above the average roof height in the city though, just to see if it would succeed.

They should build a series of big buildings on four differnt corners or something and have the buidlings lean inward across the streets to merge and form some sort of large continuous floorspace for a large retail base, how sweet would that be? However, with a building that large, the NIMBYs would flip out, which would be the fun of it of course!

I'm sure the idea of a skymall is infesable, but I like to think about things that are outside the box like this.

I guess I am just for more public spaces above floor level, like clubs and resturants and, if it could happen a skymall. I think the tops of tall buildings are wasted when they are just a bunch of offices!
