With Corwin Park as your extended backyard-green grass after green grass as far as the eye can see-this Nantucket-inspired custom home on a half-acre lot delivers the ultimate North Shore living experience with a truly five-star floor plan. Soaring ceilings and wide hallways create a sense of grand scale, layered with rich millwork, bespoke built-ins, and refined finishes that elevate every room. Dramatic double atrium foyer sets the stage with its sweeping staircase and elegant arched openings framed by intricate trim and casings. At the heart of the home lies the massive, sun-drenched great room with incredible southern exposure-naturally lighting both the inviting family room and the Chef's kitchen. The family room, anchored by a black honed marble fireplace and custom bookcases, flows effortlessly into a charming breakfast nook with oversized bay window overlooking the private, lush backyard. For larger gatherings, the formal living room extends the entertaining space with another FP and walls of windows. Just beyond the great room, discover the home's best-kept secret-a wood-paneled sunroom with East Coast flair, featuring a floor-to-ceiling stone fireplace and screened French doors that open to the outdoor oasis. The chef's kitchen beautifully balances form and function: custom cabinetry, thick stone countertops, and a massive breakfast island accented by oversized oil-rubbed bronze Visual Comfort lanterns. A hidden storage caddie and walk-in pantry keep the space sleek, while the butler's pantry connects seamlessly to the formal dining room. Everyday convenience continues with a mudroom wing featuring a full bath, office/guest room, and direct access to the three-car garage. Upstairs, the expansive second level includes four ensuite bedrooms, a secondary family room, and laundry. The hotel-level primary suite impresses with a marble fireplace, custom window seats overlooking the backyard, and dual walk-in closets. The spa bath wrapped in luxe finishes features a soaking tub beneath a picture window, steam shower, and dual vanities with rich dark cabinetry-a true private retreat. Down the wide hall, three additional ensuite bedrooms with built-out closets and full baths, while the second family room can easily convert to a fifth bedroom. Third level w/ untapped potential-ideal for a play loft, studio, or future expansion. Fully finished lower level is an entertainer's dream: a theater-style lounge, rec room with stage, private gym, office, and guest suite. From sun-splashed mornings in the kitchen to cocktail evenings in the sunroom, this home is more than square footage-it's a North Shore lifestyle statement. Grand in scale, timeless in design, and just steps from award-winning Hubbard Woods Elementary and New Trier High School, with quick highway access for an easy 18-mile drive to the city-this is exactly what you leave the city for.
