Earlier in the year I built a model of that tower, and now that we're talking about, I got inspired and added floors to make it a 22-floor building. Now this is quick and dirty, it's totally approximate, I have no idea if this is actually what it'd look like, but it's just for kicks and giggles. Oh and I put it in with Eighth and Main, JUMP, and Capital II Tower.
Current Skyline (missing the Aspen):
Skyline with proposed structures and 22-story version of Capitol Plaza.
IMO, it's probably highly unrealistic to think that all will be built, but hey we can dream.
