It is only a guess that a 100 floors skyscraper is being planned in Chicago. After all, it may just be the Willis (Sears Tower), the location of the potential project would be near the Post Office. 311 South Waker would also be a possibility for a Supertall, let’s see what else comes.
^If this was a real proposal, would it be taller than Sears? I want a new Chicago tower not only taller than Sears but bigger as well. Would be cool. Though in this climate I have no idea how you’d get financing for a building that big.
