Rarely does a property of this magnitude hit the market with the footprint and legal compliance to match its ambition. Spanning approximately 3,100 square feet across three fully finished levels, this 5-bedroom, 4-bathroom residence was expanded and renovated in 1998 to create a sanctuary of scale. Unlike many homes in the area, every luxury feature—from the massive interior expansion to the professional outdoor complex—is fully permitted and 100% legal. The Residence: Three Levels of Expansive Living Designed for the family that refuses to compromise on space, the interior flow is masterfully curated for both privacy and grand-scale hosting: The Upper Level Sanctuary: Features three "larger-than-standard" bedrooms. The Primary Suite serves as a true retreat, boasting a private ensuite bath and a spacious closet. Two additional oversized bedrooms are served by a pristine full hallway bath. The Main Level: A grand-scale floor plan featuring a massive living room and a chef-sized kitchen. The traditional dining area has been expertly converted into a light-filled executive home office, perfect for the modern professional. The Lower Level Guest Wing: A fully finished floor offering two additional bedrooms, a laundry center, and a cozy sitting area. One lower-level bedroom features its own full bathroom , offering total autonomy for guests, or multi-generational living. The Backyard: A Fully Permitted Private Resort Step outside into an entertainment complex that rivals a five-star private club. This is a "turn-key" summer lifestyle that is already fully engineered and legal: The Water: A sparkling 37’ x 17’ built-in pool designed for high-capacity fun. The Professional Cabana: A sectioned-off retreat featuring a full bathroom (shower and toilet) and a professional bar area. Commercial-Grade Amenities: The bar is a host’s dream, equipped with an all-stainless steel professional sink, dedicated refrigeration, and a high-capacity 80lb professional ice maker. Outdoor Culinary Center: A custom kitchen sheltered by a massive 24’ x 14’ permanent overhead canopy, allowing for seamless outdoor dining regardless of the forecast. The Location: Elite Access & Convenience While the estate offers total privacy, it is situated in the heart of one of Long Island's most convenient hubs: Premier Shopping & Dining: Minutes to the Plainview Shopping Centre, widely regarded as one of the highest-rated shopping destinations on the Island. You are so close to high-level restaurants, gourmet food services, and major retail. Commuter’s Dream: Located just minutes from the Hicksville LIRR Station for a seamless ride into Manhattan. Major Arteries: Immediate proximity to the Northern State Parkway and I-495 (Long Island Expressway), providing effortless access to the entire tri-state area.
