good piece here:
http://en.wikipedia.org/wiki/Landmark_Place
Landmark is 417ft.
I love the part about Frisina appealing to the city to break the height limit to save money by building up instead of out. Man, he was way ahead of his time.
He got them to waive the 6-storey height limit and built an 18 storey tower. 3 times the height of what was previously allowed.
Currently the height limit at Connaught is 25 floors. Let's see Stinson do the same thing and ALSO go 3 times higher - 75 floors!!
