Plans are underway for a striking new addition to Chicago’s architectural landscape. Developer Hines has unveiled a proposal for a 45-story office tower at 301 S. Wacker Drive, directly across from the iconic Willis (Sears) Tower. Designed by New York-based Kohn Pedersen Fox, the 800,000-square-foot tower emphasizes flexibility, wellness, and sustainability—key priorities for the evolving workplace.
The proposed office tower will rise more than 700 feet, featuring modern setbacks, terraces, and a distinctive crown. Connecting to the winter garden of 311 Wacker, the structure will occupy the southeast corner of W. Jackson Boulevard and S. Wacker Drive. While the project awaits city approvals and likely an anchor tenant, it is already drawing attention for its ambitious scope and prime location.
The design blends efficiency with aesthetics, maximizing natural light and providing dynamic city and river views.

With its prominent location on Wacker Drive, 301 S. Wacker is positioned to compete with major office developments like Salesforce Tower. The project aims to attract tenants with a blend of prime location, world-class amenities, and flexible workspace. Though estimated costs may exceed $800 million, the investment reflects confidence in Chicago’s ability to remain a hub for corporate headquarters and professional services.
301 S. Wacker represents a forward-looking vision for Chicago office space, balancing tradition with innovation. By emphasizing wellness, outdoor access, and sustainable design, the tower has the potential to redefine what modern workplaces look like in downtown Chicago. Pending approvals and tenant commitments, this ambitious development could soon rise as one of the most distinctive new landmarks on the city’s skyline.
