One of Chicago’s great Landmark Buildings, Old Colony was originally designed for “High Class Office” usage and was the first of its kind to employ a unique structural portal wind-bracing system, permitting open floor plates and thinner masonry cladding. The redevelopment retained surviving historic components including marble clad walls, interior glazed office partitions, ornate trim, mosaic floors, and precast “scagliola” plaster. Tailored to the burgeoning student population in the South Loop, the program includes ground level retail with sixteen stories of apartment-style residences with an added rooftop deck and terrace area.
