Everyone needs to chill. I'm sure the height will be fine because of the other design we saw earlier this year. That design was around 1,500 feet, and was part of the same "contest" to design 400 n lake shore drive. My guess is that they gave the actual architects the same basic framework (two towers, one around 1500 ft, the other at 800 ft) etc. Unless things have changed drastically since then, I bet the height will 1500 ft.
