A century-old landmark, reimagined for modern living. This 2005 duplex conversion of the historic St. Mary's Church pairs architectural character with contemporary design. The former Sanctuary offers soaring ceilings and original hardwood floors, while the converted Sunday School introduces an industrial aesthetic of concrete floors and exposed brick. Two distinct residences, one six bedroom home and a separate one bedroom plus study create exceptional flexibility for live work lifestyles, multigenerational living, or owner-occupancy with rental income. Open kitchens with high-end appliances and updated systems ensure comfort throughout. Set within a gated complex on a corner lot, the property includes multiple entrances, a private backyard, and onsite parking for 7 vehicles. The property benefits from documented lease history supporting the asking price and borders the largest 25-acre undeveloped parcel in Oak Lawn-offering both immediate income potential and long-term investment value.
