Arc at Old Colony 407 S. Dearborn St. Chicago, IL 60605 Client Campus/MCJ Development JV LLC Size 137 Apartments (380 beds) 17 Stories 7,000 SF Retail/Commercial 187,000 GSF Original Construction 1893-94 Original Architect Holabird & Roche One of Chicago’s great old buildings, distinguished by its distinctive curved projecting corner bays, Old Colony Building was originally designed for “High Class Office” usage and was among the tallest buildings in Chicago at the time of its construction. The structure’s innovative design reflects a symbiosis of Colonial Revival architecture and the prototypical structuralsteel technology of the era. The building was the first of its kind to employ a unique structural portal wind-bracing system, allowing for thinner masonry exterior cladding, yielding more efficient office space. The redevelopment and modernization of the structure was crafted to take advantage of the many surviving original (historic) components including marble clad walls, interior glazed office partitions, ornate trim, mosaic floors, and scagliola plaster, and to restore the original DH wood windows. Tailored to the burgeoning student population in the south Loop, the program includes ground level retail with 16 stories of apartment-style, shared residences. Building amenities include a study lounge and fitness center on the 2nd floor, and added rooftop deck and terrace area on the 17th floor. The stylish, furnished studio-, and one- to four-bedroom apartments offer high ceilings, tall windows, restored original pine flooring and inlaid mosaic tile (foyers and halls), and new granite and stainlesssteel kitchens and in-unit washers and dryers.
