An insult to Chicago's architectural bona fides
Edward Keegan,
Crain's Chicago Business
"The SCB scheme looks like a banal government-issue office building of the 1960s has been plunked down on top of the original. And it's not the contrast that's the problem. We've seen new steel and glass buildings on top of elegant masonry bases before—the best example is New York's Hearst Tower by Sir Norman Foster (who designed the Apple Store on the Chicago River).
SCB's designers have chosen to roughly follow the proportions of the Burnham base, matching their exposed metal frame to the spacing of the original building's limestone piers. They also separate the new from old with a story-tall slot of glazing and top the structure with a slightly different window mullion pattern.
None of these design moves are successful."
Good call on the Hearst comparison to a previous forumer.
