In 2017, the Blackstone and EQ Office began a massive street-to-sky transformation of the Willis Tower, once the world’s tallest buildings and still the apex of the Chicago skyline. Nearly five years and $500 million later, a new-and-improved Willis Tower is ready for its close-up. Architecture firm Gensler has repositioned the iconic supertall to reinforce an active neighborhood-scaled experience at street level while also modernizing the commercial office spaces above. Named “Catalog”—an homage to the building’s original tenant, the Sears Roebuck Company—the five-level extension features new retail, dining, and entertainment spaces, including an outdoor terrace and new public art installations by Olafur Eliasson and Jacob Hashimoto.
