A distinguished Gilded Age residence, this 1909 Kenwood mansion was built for lumber merchant Frank B. Stone and designed by noted architect William C. Zimmerman. Set on an extraordinary 70-by-297-foot lot, it combines architectural significance with the scale of a true urban estate. From 2012 to 2014, the property underwent an extensive renovation and restoration that preserved its original character while introducing modern comfort and efficiency. Improvements included custom Marvin windows, a new Vermont slate roof, copper gutters and downspouts, full tuckpointing, insulation, and replacement of the home's plumbing, electrical, heating, and cooling systems. The grounds were also completely redesigned by Scott Byron, and the driveway was relocated to enhance the property's setting and approach. Restored architectural details are complemented by exceptional craftsmanship and fully integrated technology. Original doors, hardware, cabinetry, and millwork were carefully refurbished, while custom built-ins, automated shades, Lutron lighting controls, security systems, and whole-house audio and video were added throughout. Geothermal heating and cooling, radiant-heated floors, a high-efficiency boiler, and modern architectural registers provide year-round comfort. Hand-selected Statuario marble from Carrara, Italy, was custom fabricated for use throughout the home, creating a cohesive design across the kitchen and baths. The sophisticated kitchen features custom Italian Castagna cabinetry, Liebherr refrigerators, Miele dishwashers, Bertazzoni cooking appliances, multiple dining areas, and a beautifully integrated pantry and coffee station. The home offers extensive space for recreation and everyday living, including a vaulted gym/multipurpose room with an infrared sauna, as well as an expansive lower level with a media room, bar, game and recreation rooms, and a spacious laundry room. The oversized lot allows for exceptional outdoor space, including an expansive front lawn, a raised terrace off the living room, and a spacious Indiana limestone terrace in the rear with a koi pond and built-in grill, all surrounded by mature trees and beautifully designed landscaping. Additional features include a fully fenced vegetable garden with raised planting beds. The separate coach house, with a two-car garage, was fully restored and enhanced, including new copper gutters, custom garage doors, upgraded mechanical and electrical systems, and a dramatic second-floor studio completed in 2022 with an open floor plan, lofted ceiling, and abundant natural light. Offering exceptional scale, craftsmanship, outdoor space, and modern infrastructure, this is a rare opportunity to own a residence of architectural significance and enduring quality. Ideally located in historic Hyde Park-Kenwood, this home offers convenient access to the University of Chicago, the Laboratory Schools, Jackson Park, the lakefront, the Museum of Science and Industry, neighborhood dining and shopping, and the new Obama Presidential Center.
