    COMING SOON Introducing a beautifully reimagined and expanded residence in one of East Hampton's most coveted waterfront neighborhoods. Perfectly positioned across from Three Mile Harbor with picturesque water views, this exceptional home is located in the highly desirable Settlers Landing community of Northwest Harbor. Set on an elevated 0.56-acre parcel along prestigious Three Mile Harbor Drive, and surrounded by newly built luxury homes and waterfront estates, this property offers not only an extraordinary lifestyle but also an outstanding investment opportunity in one of the Hamptons' most sought-after locations. Just moments from Hands Creek Harbor, Sammy's Beach, and Gardiners Bay, this is a dream setting for boating, paddleboarding, kayaking, swimming, or simply enjoying the natural beauty of the waterfront. Ideally situated between the villages of East Hampton, Sag Harbor, and Amagansett, you'll have effortless access to the East End's renowned beaches, boutiques, restaurants, and cultural attractions. Designed for both everyday comfort and effortless entertaining, the home welcomes you with a gracious entry foyer that opens into a dramatic double-height living room filled with natural light. The chef's kitchen is beautifully appointed with premium Viking and Bosch appliances, including an eight-burner gas range and an additional double-drawer refrigerator. A spacious secondary living area and expansive wraparound deck create a seamless indoor-outdoor lifestyle, perfect for summer gatherings. The first floor is completed by a generous guest bedroom with an en-suite bath and an elegant powder room. Upstairs, the luxurious primary suite captures stunning harbor views through oversized windows beneath soaring ceilings. A comfortable sitting area provides the perfect place to relax while taking in the scenery, and the spa-inspired bath has been thoughtfully designed with impeccable finishes throughout. Two additional bedrooms, both featuring high ceilings, share a beautifully appointed bath with double vanities. The harbor-facing guest bedroom enjoys the same tranquil water views. The finished lower level adds approximately 1,000 square feet of versatile living space, including a fifth bedroom, a spacious recreation room - ideal for a home theater, fitness studio, game room, or lounge, a fourth spacious full bath, laundry room, and an indulgent sauna. A separate exterior entrance provides direct access to the pool and outdoor entertaining areas. Outside, the newly renovated 20' x 40' heated pool is surrounded by an elegant bluestone perimeter, lush professional landscaping, an outdoor shower, and an expansive wraparound deck designed for relaxing and entertaining. The generous lot also offers room for future enhancements, including a detached garage or pool house. As a resident of Settlers Landing, you'll enjoy access to the private neighborhood beach, where spectacular sunsets and Fourth of July fireworks create unforgettable summer memories. Launch a kayak, moor a boat just down the street, or simply embrace the peaceful waterfront lifestyle that makes this neighborhood so special. Offering exceptional craftsmanship, luxurious amenities, and an unbeatable harborfront setting, this is a rare opportunity to own a beautiful new Hamptons retreat in one of East Hampton's most desirable waterfront communities.
