The Chicago Tribune posts graphics and images (registration req'd) for the Wrigley Field bleachers renovation, part of a larger plan that also includes a parking garage, restaurants and retail.
For the passer-by, the most notable change will be the walkway will cantilever over the sidewalk.
Granted this ain't exciting architecture, but it's been a heated debate...
...because of these neighbors and their right to peer into Wrigley Field during games, charging admission and receiving $$ that might otherwise go to the Cubs (and its parent, the Chicago Tribune). Notice the construction at the bottom of the image.
