Nestled on a quiet cul-de-sac, south of the highway in the hamlet of Remsenburg, 4 Bayberry Lane offers the perfect balance of modern luxury and old-school Hamptons charm. Thoughtfully renovated in 2014-2015, this 4-bedroom, 3.5-bath home spans 2,410 square feet on just under an acre of beautifully landscaped grounds designed by Dragonfly Landscape Design. Inside, hardwood floors, recessed LED lighting, and smart features create a sophisticated yet comfortable atmosphere. In the aptly named "Upside Down House," the first level hosts a serene primary suite complete with a gas fireplace, three closets, a spa-like bathroom with soaking tub, oversized glass shower, and double vanity, plus sliding glass doors leading to a private patio. Two additional bedrooms are ensuite, each with access to the pool patio through sliding glass doors, while the fourth bedroom-currently used as an office-shares a hall bath. Upstairs, the open living and dining spaces showcase water views, a gas-burning fireplace and access to two balconies and a rear deck. The renovated kitchen is replete with quartz countertops, Bosch stainless steel appliances, induction cooking, and a walk-in pantry. Outdoors, the freshly reimagined backyard is a rarely found oasis with a heated, 20' x 40' gunite pool, new pool heater and filter (2025), room for a pickle ball court, a built-in firepit with surrounding benches, and dedicated gas and electric lines for a future outdoor kitchen. Additional highlights include a detached two-car garage, gravel driveway with EV charger, new HVAC system (2025) with smart Honeywell thermostats, hardwired security system with cameras, and full irrigation. With beach rights to Rogers Beach and Lashley (Jetty 4) in Westhampton Beach Village and just 75 miles from Manhattan, this property offers access to all in a serene Hamptons setting.
