Like nothing else on the market. Tucked discreetly behind a soaring holly hedge and gated drive, this exceptional residence offers a rare blend of refined living and secluded serenity in Lake Grove Village. Built in 2006, this custom ranch was thoughtfully designed to provide a sanctuary of sophisticated comfort alongside ideal spaces for guests and entertaining. Enter and be captivated. The open-concept living room, kitchen, and dining area feature timeless features -- hardwood floors & soaring 10-foot ceilings. Unique architectural details throughout the home include massive oak doors, a custom-built fireplace and built-in bookshelves. Expansive sliders offer a wall of glass that invite in views of the spectacular .44 acre. The Silestone and stainless steel kitchen with center island is both functional and stylish, while the king sized primary suite features a luxurious ensuite bath with soaker tub, separate shower, double vanity and walk-in closet. Storage is plentiful, with an oversized two-car garage and a substantial, stand-up attic (prepped to build up if desired). A high-ceilinged basement with outside entrance offers incredible potential and versatility. Home gym. Radiant heat. Surround sound. The resort-style property is a true showstopper. The beautifully landscaped grounds feature multiple gathering areas and a sparkling, heated saltwater pool. Relax beneath the breathtaking veranda, unwind beneath the poolside pergola, or gather around the firepit. Shaded paths, vine-covered archway, lush plantings, and mature trees offer complete privacy. This is more than a home; this is a lifestyle. A rare and remarkable offering 11 minutes to Stonybrook Hospital & University. Moments to shopping and amenities. See Video Tour! Must be experienced to be appreciated. The one.
