Pristine, waterfront, mid-century modern oasis, with 100 feet of private, sandy, beach on the Long Island Sound. Situated perfectly on 1.38 acre for total privacy, enjoy expansive views of the Long Island Sound from the living room, primary bedroom, kitchen, and screened in porch. Nestled at the end of a long, country driveway, this hidden gem has been impeccably maintained and artfully restored. All major upgrades have been completed, including new roof, mahogany decking, new central air, new hot water heater, and all new hi-end appliances, including Bertazzoni range and commercial grade washer and dryer. Restored and upgraded features to enhance the mid-century architecture include honed, black granite countertops, grass cloth wallpaper throughout, Lightolier ceiling fixtures, and for the cooler months, a beautiful, restored, stone fireplace, with a pitch perfect updraft. The exterior has been freshly painted, with all new copper screened in mahogany porch, copper gutters and an outdoor shower. The spacious, open concept walkout basement offers the opportunity to double your square footage if you choose to finish it – the possibilities are endless. Walking paths cut through mature, indigenous specimens, including bayberry, red cedar, and flowering cactuses. Sandy clearings provide space for picnicking and grilling, in your own, low maintenance nature preserve. But just beyond is what you came for – the breathtaking, private, sandy beach with lapping waves and endless views of the horizon above the Long Island Sound. Additionally, just 1 block away, you’ll find Mt. Sinai Harbor, multiple marinas, an ecology center, fishing pier, basketball and beach volleyball courts and a seasonal clam shack. Located perfectly in the middle: 70 miles to NYC and 65 miles to Montauk. Feels like Fire Island on the North Shore.
