A rare Hudson Valley country estate, Rose Lodge offers exceptional privacy, scale and versatility on 17.9 acres, with a private lake, beautifully sited pool, terraced gardens, sweeping level lawns and multiple residences, all less than an hour from Manhattan by express train. Rich in history and once owned by the Gilded Age Van Cortlandt family, the beautifully restored 1840 main residence is not landmarked, allowing its historic character to coexist with modern living. Inside, a striking checkerboard marble foyer introduces gracious, light-filled rooms with beautifully preserved period details. Elegant formal spaces flow naturally into a welcoming family room and bar surrounded by windows overlooking the grounds. A 2026 spacious chef's kitchen with center island and adjoining butler's pantry is equally suited to everyday living and entertaining. The private quarters offer remarkable flexibility. The spacious primary suite enjoys elevated views toward the lake, while additional bedrooms accommodate family and guests. A dedicated home office and private theater provide exceptional work-from-home and leisure spaces, and the uppermost level offers two expansive rooms ideal for additional bedrooms, studios or creative space. Beyond the main residence, an impressive five-car garage connects by breezeway to the stable complex. A completely remodeled one-bedroom apartment above the stable wing and a separate two-bedroom stone cottage create exceptional possibilities for guests, extended family, private offices or independent living. With nearly 18 acres of landscaped grounds, mature trees, nature paths, substantial level lawn, pool, private lake, stonework and multiple outbuildings, Rose Lodge offers the increasingly rare opportunity to create a true private compound in the Lower Hudson Valley, combining the space and serenity of country living with convenient access to New York City.
