Chicago's $500M Willis Tower renovation shows off curvy new skylight
from Curbed - Chicago
As construction on the 300,000-square-foot “Catalog” addition at the base of Willis Tower progresses, crews recently completed the large curving skylight capping the project’s upcoming retail and dining hall. The swooping 240-pane diagrid window will not only flood the space with light, but provide unobstructed views of the famous 1,453-foot-tall skyscraper above. Designed by the Chicago office of global architecture firm Gensler, the overhaul of the building’s base is the most visible part of a larger $500 million renovation plan unveiled in 2017.
