Step 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. The hulking 1920s-era structure will become 2.8 million square feet of office space, with many notable tenants already signed and moving in. This massive and complex undertaking began with the 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.
