In addition to new elevators and tenant amenities, the skyscraper’s owners are expected to announce their plan to add "unique retail and entertainment" options to the iconic tower’s base.
After purchasing Chicago's tallest building for $1.3 billion last year, the Blackstone Group plans a $150 million overhaul of the Willis Tower. Roughly 150,000 square feet of new retail and dining is slated for an addition at the tower's base.
