Also agree. The stone or concrete base really nauseates me. It's really a step backwards into the 00s. What's more annoying, I like the tower just fine.
What's with the un-treated green area? Is that reserved for a second or addition development? If so, then I'm actually not worried about the base. That is, if something were built, facing Illinois, the base then would become obscured and therefore unnoticeable. Anyway, whatever, at least it's another neat looking glass tower, right?
