Welcome to "Sui Generis"-aptly named from the Latin phrase meaning "of its own kind" or "in a class by itself." Uniquely designed by a renowned architect and ideally situated on one of the highest points in Seaview, Fire Island, this extraordinary residence is truly one of a kind. Beautifully renovated within the past few years, this exceptional 3-bedroom, 3-bathroom home blends modern luxury with timeless coastal charm. Each spacious bedroom occupies its own private level, creating a unique sense of privacy and comfort. The extensive renovations include new flooring throughout, custom bedroom cabinetry, a kitchen with modern flair, and three beautifully updated bathrooms. High ceilings on every level create an airy atmosphere, while split-unit air conditioning in every room and a central vacuum system provide convenience. The upper level features two spacious decks, one of which leads to an incredible rooftop deck where you'll enjoy breathtaking panoramic views of both the Great South Bay and the Atlantic Ocean-an ideal setting for morning coffee, sunset cocktails, or entertaining. Perfectly located just moments from the Seaview Ferry, market, and pristine ocean beaches, the home also offers convenient access to the Seaview Bay Beach, where residents can enjoy additional amenities including tennis courts, a playground, and a protected swimming area.
