    Welcome to 66 Adelhaide Lane, East Islip — a rare pre-sale opportunity to own a custom-built new construction residence south of Montauk Highway on an oversized property backing up to a tidal lake with unobstructed water views and water access. Set within one of East Islip’s most prestigious communities, this one-of-a-kind home is being handcrafted by a highly experienced Long Island builder, with approved permits in place and construction moving forward. Estimated completion is set for the end of 2026, giving buyers the unique opportunity to personalize select finishes, including cabinetry, tile, vanities, paint colors, and more — without the stress or uncertainty of starting from scratch. Designed with luxury, function, and natural light in mind, the home will feature soaring ceilings, a dramatic open foyer, a massive living room with gas fireplace, and a custom kitchen with quartz countertops, premium appliances, and high-end black tilt-and-turn windows throughout. The rear of the home opens to an expansive deck overlooking the oversized yard and tidal lake, creating an incredible setting for entertaining, relaxing, and enjoying true waterfront views. The primary suite is designed to impress with walk-in closets, large sun-filled windows, a spa-inspired bath with walk-in rainfall shower, separate soaking tub, and elegant modern finishes. Additional highlights include central air, attached garage, new driveway, paver patio, and a thoughtfully designed floor plan built for today’s lifestyle. A rare chance to secure a custom waterfront-style new build in East Islip before completion.
