Beyond private gates, a grand wrap-around driveway framed by stately pillar archways creates a striking sense of arrival, surrounded by expansive, manicured grounds offering complete seclusion. This impressive three-story residence, including a fully finished basement, is thoughtfully designed and served by an elevator accessing all levels. Inside, a dramatic foyer showcases refined architectural details and crown molding throughout. Every bedroom features its own en suite bathroom and walk-in closet, providing exceptional comfort and privacy. Dual primary suites, each with a fireplace, offer luxurious retreats, while additional fireplaces in the formal living room, family room, and dining room bring the total to five fireplaces throughout the home. The chef’s kitchen is a showpiece, appointed with high-end appliances, generous workspace, a wine refrigerator, and seamless flow to the fully equipped outdoor kitchen, ideal for entertaining. Additional features include a whole-house water softener system and a Generac generator that powers the entire home, ensuring year-round comfort and peace of mind. The finished basement is an entertainer’s paradise with a private theater, full bar, and game room. Upstairs, enjoy a fully equipped fitness room with steam shower, a spacious loft, and an elegant extended hallway enhancing the home’s open flow and sophistication. Security and functionality are exceptional, featuring a full surveillance and alarm system with license plate readers. The property offers a garage accommodating up to nine vehicles, along with additional RV parking on the side yard.
