Nestled on a quiet corner lot in the heart of Sag Harbor Village, this beautifully designed 4-bedroom, 3.5-bath home offers the perfect blend of luxury, comfort, and coastal charm. Thoughtfully crafted with an open floor plan and soaring 9-foot ceilings, the home is centered around a dramatic living room open to above, complete with a wood-burning fireplace and gas hookup option for added convenience. The first-floor primary suite is a private retreat featuring direct access to the expansive mahogany deck and a spa-inspired bath with an antique clawfoot tub, oversized walk-in steam shower, marble bench seating, and multiple body sprays. The chef's kitchen flows seamlessly into the living and dining areas, creating an ideal space for entertaining and everyday living. Upstairs, a loft overlooking the main living space adds architectural interest and flexibility, while two additional bedrooms share a spacious bath with full tub. A cozy reading nook and additional sitting area complete the second floor. A dedicated office or playroom provides even more versatility. Outdoor living is equally impressive. The large mahogany deck with stainless steel cable railings surrounds an inset hot tub and overlooks a heated saltwater Mountain Lake pool, all framed by mature landscaping, hydrangeas, roses, beach grasses, and privacy-enhancing arborvitaes. Additional features include radiant heat, central air, high-ceiling full basement, irrigation system, covered front porch, and fully fenced grounds. Located just moments from the shops, restaurants, and marinas of Sag Harbor Village, with access to Sagg Main Beach and Long Beach through Southampton Town beach privileges, this exceptional home captures the essence of Hamptons living.
