Nestled in the heart of Water Mill South, this historic luxury estate is a rare opportunity to own a masterpiece of Shingle Style architecture. Renovated in 2007 and conceived and built in 1885 by Henry Turbell Rose, Rosemary Lodge stands as a testament to exceptional craftsmanship and enduring elegance. Just minutes from the ocean, 0.93-acre grounds featuring a 4,110-square-foot residence, pool house, and a pool. This beautifully designed home boasts 5 bedrooms, 4 bathrooms, and 1 half bathroom. Impeccably preserved, the home retains its museum-quality original paneling, hand-carved woodwork, stained glass windows, and intricate moldings. Each of the five bedrooms was individually crafted. The central living hall, paneled in ash, sets the tone for this architectural gem, while four working fireplaces feature hand-carved mantels, hidden cupboards, hand-painted designs, and custom tile inserts. Throughout the home, delicate floral motifs, ships, butterflies, and birds are carefully etched into the wood, along with the initials 'RL,' a homage to its storied past. The grand master suite is a private sanctuary, complete with a spa-like ensuite bath, a spacious walk-in closet, and a romantic terrace overlooking serene Hamptons farmland. A second-floor media room with a big-screen TV and fireplace offers the perfect retreat for gatherings. Designed for elegant entertaining, the chef's eat-in kitchen features a massive center island, professional gas stove with broiler, and seamless access to the outdoor lounge and dining area. Outside, a meticulously maintained rose garden greets visitors at the entrance, while the lush backyard oasis boasts a heated pool, pool house with a full bath and outdoor shower, and an alfresco cooking station with a large refrigerator and vegetable garden. Additional modern amenities include a state-of-the-art darkroom for film and photographic development, a dedicated exercise and bicycle shed, ample storage, and a newly installed electric vehicle charging station. Recognized in Houses of the Hamptons, Rosemary Lodge is listed on both the State and National Register of Historic Places for its exceptional integrity and preservation.
