Ideas / Reimagining the Thompson Center

As the original architects of the James R. Thompson Center, Jahn is proud to be part of the team that is bringing the building’s design into the 21st century while maintaining its iconic form. When it opened, the Thompson Center was intended to be a new kind of gathering space for Chicagoans. After all, it’s the only building in the city where six L train lines converge — connecting Chicago’s South, West and North sides. With a new and improved CTA experience, the Thompson Center will continue to serve commuters and will be perfectly positioned to welcome current and future employees from every corner of Chicago. The Thompson Center’s signature 17-story, light-filled atrium will remain. Additionally, the covered colonnade at the base of the building will be redesigned to allow for an enhanced ground floor experience, including opportunities for more food and beverage retail and seasonal activations of the plaza.
