Location: Chicago, Illinois
Since coming in second place on Curbed Chicago's recent ranking of most expensive listings, this Gold Coast mansion has chopped $2.5M off its ask. But it's as swanky as ever. Originally a Commonwealth Edison substation dating back to 1916, the building was transformed in the late 2000s into an eco-conscious single-family home.
After purchasing the property for $3.75M in 2008, the owners enlisted local architect Michael Hershenson to convert the two-story building. The overhaul saved the original facade, but added two additional stories to the structure and an airy central atrium, plus sustainable features like a solar heated pool. geothermal heating/cooling, and a green roof. The massive 15,000-square-foot offers six bedrooms, six baths, two kitchens, an office, library, wine cellar, exercise room, and play room. Even more impressive though may be its spacious terrace and courtyard, all with commanding skyline views.
