A truly extraordinary single-family residence, designed and built by the developer as his own personal home with an uncompromising commitment to quality, craftsmanship and longevity. Built to last using the finest materials, this one-of-a-kind property is an architectural statement that redefines luxury urban living. A private entrance on Janssen Street leads to a personal three-stop elevator and an extraordinary 40-foot atrium illuminated by a 400-square-foot curtain wall of industrial glass and crowned by a dramatic 10′ x 10′ glass skylight, flooding the interior with natural light. The residence showcases soaring 14-foot ceilings, 18-inch crown molding juxtaposed with exposed structural steel elements, maple hardwood floors, custom seamless stainless-steel railings and thoughtfully designed lighting throughout, including fixtures by Darcy Bonner and Holly Hunt. Three wood-burning fireplaces add warmth and character throughout the home. The chef’s kitchen is exceptionally appointed with Sub-Zero refrigeration, a six-burner Viking range, additional Viking convection oven, Viking microwave, warming drawer, six Viking wine coolers, built-in Miele coffee maker, quartz countertops and backsplashes, and new dual Bosch dishwashers. Four bedrooms occupy the upper level, including an impressive primary suite enhanced by four additional skylights, an Amerec steam system and whirlpool bath. A spacious custom-designed private office occupies its own dedicated floor, creating an exceptional work-from-home environment with complete separation from the main living spaces. Outdoor living is equally impressive, with approximately 1,300 square feet of private outdoor spaces. A spectacular entertaining terrace flows directly from the main living area, while the roof decks provide an unmatched view of the Chicago skyline. Additional features include garage parking for two cars plus exterior parking for three additional vehicles, a heated driveway, tool room, abundant storage, two sets of LG washers and dryers, a full sprinkler system and numerous building mechanical systems and components that were completely upgraded in 2025. A rare opportunity to own a builder’s personal residence where exceptional construction, architectural design, expansive outdoor living and income potential come together in a phenomenal Chicago location.
