It has potential I suppose. It could end up having a nice clean look to it. Also, the rendering seems to show the other half of the building having some more glass. In that way, if it really is the case, it could resemble the IBC Bank Plaza where one side of it has square windows with the other side having a curtain wall of glass. It might not be so bad then. Also, I'm kind of liking the idea of having a new building that is not blue. lol
My guess is it'll be somewhere around 170 to 190 feet tall. The Whole Foods HQ is 136 feet, and this looks to be 40 feet or so taller, not counting the mechanical penthouse, which could add another 10 to 12 feet.
