Speaking of preservation, does that section of Michigan Avenue currently look like this 1907 photo?
Not really, huh. Tall(er) buildings overtook what was once an area full of lowrise buildings and mansions. But we still love the streetwall, don't we?
Times are changing, and from the looks of it, there doesn't seem to be much worth preserving except for the Michigan Avenue facing facade.
Just saying...
Edit:
Adding a new building will dramatically change the skyline but I don't think it will take any more away from the streetwall than the stuff above and buildings like Smurfit-Stone, the Heritage, the addition to the Hilton building, Park 1000, Spertus, etc. and even going further up, the glassy addition to the Hard Rock Hotel.
