More people are moving downtown, and the housing for them is coming too: today sees plans for another very tall building going up downtown. Studio Gang is building an 83-story building east of downtown, not far from the often discussed Fordham Tower (which was approved, btw). The new building's name: Aqua. In other architecture news, if you're wondering what that building is by Old Orchard on the Edens, you can view the website. It's another development by Optima, who develed many of the futuristic looking towers in downtown Evanston.
