The historic adaptive reuse of Chicago’s former central post office facility transforms a gateway property into a hub of mixed-use activity. Residences, offices, hotel space, and retail outlets are all important components of this 1.7 million square foot facility. A key feature of the complex will be a ‘neighborhood park’ in the sky. Hoerr Schaudt is designing a 2.3 acre green roof of rolling topography to incorporate a variety of uses, including a play area, dog run, meadow, and quiet recreation spaces. The firm is also designing a new Riverside Plaza Park on the northeast corner of the site along the Chicago River.
