Located within the gated Wynstone community, 3 Hillburn Court sits on 1.5 acres of mature, professionally landscaped grounds and offers more than 10,500 square feet of living space. Surrounded by the beauty of Wynstone's renowned Jack Nicklaus Signature Golf Course, this private North Barrington estate offers exceptional space, privacy, and versatility. A complete transformation of the grounds has unveiled breathtaking, panoramic golf course vistas that were previously hidden, while the newly reimagined backyard creates a private sanctuary designed for seamless indoor-outdoor entertaining against a backdrop of rolling greens and endless horizons. A new DaVinci composite roof was installed in 2026. Inside, soaring ceilings, custom windows, beautiful wood floors, abundant natural light, and architectural details create a sophisticated yet comfortable setting. The reimagined de Giulio kitchen features new cabinetry, breakfast bar and beverage center (2022), a new six-burner Wolf cooktop (2025), and Bosch dishwasher (2025). The kitchen opens to the family room and expansive deck, painted in 2025, overlooking peaceful wooded views. The home offers six spacious bedrooms, luxurious baths, a sunroom, private main-level guest suite, and a second main-level family room, providing plenty of space for everyone to spread out. The primary suite features an impressive walk-in closet with built-in cabinetry, an oversized shower with multiple shower heads, and a luxurious Bacchus I tub. An oversized four-car garage offers abundant storage, with additional storage added in 2022, plus a bonus room above the garage currently used as a yoga and meditation room. The walk-out lower level provides expansive recreation and gathering space, a dedicated exercise room, and flexibility for guests or multigenerational living. The generous separation from the main living areas makes it ideal for entertaining or giving guests their own space. Additional updates include a new washer and dryer and renovated laundry room (2022), new foyer and kitchen lighting (2025), upgraded electrical (2021), and a top-of-the-line ADT security system (2022). The massive deck and private wooded setting provide an exceptional backdrop for entertaining. Wynstone offers gated security, private club amenities, championship golf, and access to the award-winning Barrington School District, all minutes from shopping, dining, Metra, and major expressways.
