Totaling up to $500 million, the renovations will include six floors of new retail space, an outdoor deck and a winter garden—all intended to entice tourists into the Tower, report www.dnainfo.com. Other potential new amenities include a rooftop skating rink and a 50,000 square foot digital attraction.

The project, which is spearheaded by the building’s owners the Blackstone Group L.P., will begin this month and end in the summer of 2019. Mayor Rahm Emanuel said the project should create 2,500 jobs.
Blackstone Group L.P. bought the tower, the world’s tallest until 1996, nearly two years ago with plans to improve its retail shops and 103rd-floor Skydeck observatory. The building defines Chicago’s skyline and hosts more than 1 million visitors annually.
“No longer will this be an inaccessible fortress without amenities that does feel a bit desolate after 5 p.m.,” said Jon Gray, Blackstone’s global head of real estate. Blackstone is footing the renovation’s entire $500 million bill, which the company said is its largest investment ever in a building.
The renovation includes 300,000 square feet of new retail including “dining and entertainment” at the base of the tower, as well as a new 30,000-square-foot outdoor deck.
At 1,450 ft this tower is the third tallest building in world, at time of writing in 2017.
There are 110 storeys and the main building use is offices.
