Five spacious bedrooms-including a first-floor ensuite guest room and a luxurious upstairs primary suite with spa bath, walk-in California Closet, and soaking tub-ensure comfort and privacy. All bathrooms feature premium finishes, custom tile, and seamless glass enclosures.The home flows seamlessly to indoor and outdoor entertaining spaces. The screened-in porch, complete with retractable Phantom screens, wood-burning fireplace, and Samsung Terrace TV, leads to the meticulously designed backyard with a heated 20' x 40' saltwater pool, bluestone patio, built-in DCS grill kitchen, and half-court sport court. Every inch of the grounds is thoughtfully lit, irrigated, and artfully landscaped. The attached two-car garage, laundry room with dual Whirlpool sets, and smart home features including multi-zone HVAC, remote-access security, blackout drapery, and built-in dehumidification system offer a turnkey experience. With beach rights to both Rogers and Lashley (Jetty 4) beaches, and located just 81 miles from Manhattan, 17 Griffing Avenue is a rare opportunity to own a fully rebuilt legacy home in one of the Hamptons' most exclusive coastal enclaves.
