Graham, Anderson, Probst & White, 1921


Gensler, 2019


Be one of the first to set foot inside the rapidly transforming Chicago Post Office, the largest adaptive reuse project in the nation. 601W Companies and the Chicago office of Gensler are spearheading the $600 million project, slated to complete in late 2019. In the end, the hulking 1920s-era structure will become 2.8 million square feet of office space anchored in part by Walgreens’ 200,000-square-foot lease for digital and e-commerce operations. This massive and complex undertaking began with restoration of the historic lobby, and will continue with the addition of a new food hall, a three-acre rooftop terrace for building tenants, and a public riverwalk.

Behind the Scenes

Visitors to the Chicago Post Office will have exclusive access to the restored and modernized lobby.
