Structural work has reached the roof level for a six-story mixed-use building located at 1123 W Randolph Street in West Loop. The project is being developed by Interra Realty, who plans retail space on the first two floors and nine apartments on the third through sixth floors. The seventh level will house a rooftop enclosure and 740-square-foot deck available to residents. Previously, the site was occupied by a parking lot. While the project will only span 16,000 square feet, its height of 69 feet and Floor Area Ratio of roughly 5.0 reflects a recent westward shift in density along the Randolph Corridor.
