Reimagined and inspired, the 1125 Longvalley Estate offers a rare opportunity on one of the largest remaining acreages on the North Shore. Privately set behind mature trees and bordered by a rolling river, tranquil pond, and sweeping golf course views, this exceptional property delivers a true 360-degree natural setting just moments from town, Metra, top-rated schools, and only 25 minutes to downtown Chicago and O'Hare. Originally built in 1927, the home blends timeless architectural character with thoughtful updates and incredible potential. Re-envisioned with virtual renderings by Lauren Collander Interiors, the residence showcases expansive living spaces designed for both everyday living and grand entertaining. A formal living and dining room feature a classic limestone fireplace, herringbone wood flooring, and floor-to-ceiling windows overlooking the pool and scenic grounds. A dramatic 40-foot family room flows seamlessly into a billiards area, bar, and sun-filled atrium with soaring ceilings and radiant heated floors. The separate chef's kitchen includes an adjoining family room and breakfast area with views of the expansive west drive-ideal for future recreation or sport court possibilities. Outdoor living is equally impressive, with heated bluestone patio floors, an outdoor fireplace, and year-round enjoyment of the surrounding landscape. The renovated pool house includes a full bath and kitchenette, complemented by Ipe decking and bluestone surround. Upstairs, a grand library and private office capture panoramic views, while six additional bedrooms and baths include a spacious primary suite overlooking the pool and grounds. The lower level offers flexible space for recreation or future customization. A rare offering combining scale, privacy, and unmatched natural beauty. *Some Photos are Virtual Renderings of what a buyer can do with the current space.
