20 Oak Lane Experience the best of the East End from this waterfront retreat in Hampton Bays' exclusive Old Harbor Colony. Set on a quiet street with beautiful water views, 20 Oak Lane offers a rare blend of space, light, and true boating lifestyle-just minutes to ocean beaches, waterfront dining, and everything the Hamptons have to offer. With over 4, 200 square feet of interior living space plus a two-car garage, five bedrooms (including two primary suites), four full baths, and one half bath, this home is designed for relaxed coastal living and effortless entertaining. Step outside to your private backyard oasis featuring a recently relined pool (2024), expansive deck, and a 120-foot composite bulkhead-offering exceptional dockage capacity for multiple boats or larger vessels, with easy access to the bay and ocean. Inside, cathedral ceilings and natural light define the main living spaces. The spacious kitchen offers abundant cabinetry, generous island prep space, a stove plus two wall ovens, and direct access to the deck and pool. Adjacent, the butler's pantry provides additional cabinetry, counter space, plus a refrigerator, a sink, and convenient access to the laundry room and attached two-car garage. Multiple gathering areas-including a family room with gas fireplace, a living room with wood-burning fireplace, and a sunroom with a door out to the deck and pool-create an ideal flow for both everyday living and entertaining. Upstairs, a primary suite offers a private, elevated retreat with its own living area, mini-kitchen, walk-in closet, large ensuite bath, and a deck overlooking the water. The layout also includes a main-level bedroom and full bath, along with another spacious primary suite. A large recreation room provides additional space for relaxing, games, or media. Two additional bedrooms with cathedral ceilings and a shared Jack-and-Jill bath complete the upper level. Whether you're spending the day at Ponquogue Beach, boating from your backyard, or enjoying summer evenings by the pool, this is Hamptons living with space, comfort, and exceptional waterfront access-without compromise.
