A truly extraordinary residence, seamlessly blending ultra-refined private living. Designed and built by the developer for personal use, the property is without equal—an architectural statement that redefines luxury urban living. A private entrance on Janssen Street leads to your personal three-stop elevator, opening into a dramatic forty-foot atrium lit by a four hundred square foot curtain wall of industrial glass and crowned with a ten-foot by ten-foot glass skylight that floods the home with natural light. The residence features fourteen-foot ceilings, eighteen-inch crown molding accented with exposed structural steel components, custom lighting throughout, including designer fixtures by Darcy Bonner and Holly Hunt. The chef's kitchen is impeccably appointed with Sub-Zero refrigeration, a Viking range/oven, an additional Viking convection oven, six Viking wine coolers, and dual Bosch dishwashers. Highlights continue with three wood-burning fireplaces, maple hardwood floors, stainless steel railings, a full sprinkler system, and two sets of LG washers and dryers. Four bedrooms occupy the upper floor with exquisite finishes and two bathrooms. The primary suite includes four additional skylights. A spacious, custom-designed private office occupies its own dedicated floor, offering the ultimate work-from-home sanctuary. Outdoor living is equally impressive, with approximately one thousand three hundred square feet of outdoor space on four levels, showcasing breathtaking Chicago skyline views and a spectacular entertaining terrace that flows directly from the main living space. Supplemental amenities include garage parking for two cars and outside parking for three additional vehicles. More features include a heated driveway, tool room, abundant storage. Many of the building's mechanical elements were completely upgraded in 2025. The building is approximately seven thousand eight hundred square feet per construction documents. A rare opportunity to own an architectural masterpiece that combines luxury and unmatched design in a phenomenal location. Owner is a licensed real estate broker.
