Willis Tower Repositioning

Chicago, Illinois

Gensler carefully studied how existing spaces in Willis Tower were being used in order to create a true Chicago-born environment that reinforces a highly active, neighborhood-scaled experience. Named “Catalog,” an homage to the building’s original tenant, the Sears Roebuck Company, the reimagined base of Willis Tower connects Chicagoans and visitors with five levels of retail, dining, shopping, and immersive entertainment. The design extends the streetscape, creates community, and engages visitors in a one-of-kind, only-in-Chicago experience.

From street to sky, the repositioned building provides inviting hospitality on an unmatched scale, dissolving the borders between work and life, and fostering a collaborative, warm atmosphere. In 2023, Willis Tower was recognized as Winner of AIA National’s Interior Architecture Award and in 2022, Willis Tower was named a Winner of AIA Chicago’s prestigious Design Excellence Awards.
