Single Family Home for sale in Mattituck, NY

for $4,775,000 with 3 bedrooms and 3 full baths, 2 half baths. This 3,557 square foot home was built in 1986 on a lot size of 2.45.

Perched on a 100-foot-high bluff with commanding views of Long Island Sound, this exceptional 3 + bedroom, 5 bath contemporary home is a rare fusion of design, privacy, and natural beauty. Originally designed and built in 1986 by architect Sanford Hanuer for his own use, the 3,348 sq ft residence was completely reimagined in 2011, preserving its architectural integrity while introducing luxurious modern updates. Set on 2.45 acres with 190 feet of private beachfront, the home is sited at an angle to capture uninterrupted water views from every room. Floor-to-ceiling windows, bluestone and wide ash plank flooring, and three fireplaces create a warm yet sophisticated interior. The Eggersmann-designed kitchen with butler’s pantry is a chef’s dream, and the home’s layout includes a loft and multiple decks and patios ideal for seamless indoor-outdoor living. The white-stained cedar exterior blends harmoniously with the surroundings. Below the home, a 50-foot pool with lanai and expansive deck is tucked 10 feet down the bluff, preserving both privacy and unobstructed views. Two + bedrooms are sectioned off to serve as a separate guest cottage. Every inch of this property has been thoughtfully designed to elevate the art of waterfront living — from floor to ceiling windows, white Italian marble bathrooms to golden-hour dinners on the patio overlooking the Sound. This is not to be missed!
