The McCormick Double House, constructed in 1875, stands as a singular testament to Chicago's rich industrial past and architectural resilience. It is the sole surviving structure among a collection of homes built by two generations of the McCormick family, whose vast industrial empire profoundly shaped the city's growth until the 1950s. Following the devastating Great Chicago Fire, Chicago mandated brick construction, and the McCormick Double House emerged as one of the city's finest and oldest extant examples of Italianate architecture, distinguished by its exquisite detailing and superior craftsmanship. CBRE, Inc. and Zatz Realty Group, LLC, as exclusive agents, are pleased to present the private offering of 660 North Rush Street, a 15,410 square-foot, fully renovated Chicago Historic Landmark that currently serves as a discrete and secure family office.
