Hines Acquires Iconic Boeing Tower for $22 Million, Signaling New Chapter for West Loop Landmark

By Socialhood News · Il/Chicago/West Loop · December 26, 2025

Real estate giant Hines has purchased the former Boeing headquarters office tower in Chicago's West Loop for $22 million, partnering with New York-based Stahl Organization. The joint venture acquired the 36-story building at 100 N. Riverside Plaza from the aerospace company in a deal finalized last month, kicking off a new chapter for the 776,000-square-foot riverfront property.

The prestigious development firm, known for nearby projects like Salesforce Tower Chicago and 444 W. Lake St., already has a head start on revitalizing the landmark. Boeing will maintain a presence in the building, leasing back 70,440 square feet on floors 27 through 29 as part of the sale, with the lease running through August 2032 with two five-year extension options. Hines is now actively seeking large tenants to fill remaining vacancies in the nearly 30-year-old building, which benefits from a prime location in a market with limited newer riverfront office options.

West Loop residents and businesses can expect renewed energy around this iconic riverfront property as the new ownership brings fresh vision to the space. The acquisition reinforces ongoing momentum in the neighborhood, which continues to attract significant investment despite challenges in the broader office market. Community members interested in the building's transformation can watch for upcoming announcements as Hines unveils specific renovation and leasing plans in early 2026.
