The formal dining room makes every gathering an occasion with its artisan fixture and vibrant designer accents. A sophisticated wet bar rounds out the main living area - ideal for entertaining. Downstairs features three spacious bedrooms, two and a half baths, and an incredible laundry room/office space/ mudroom off the garage. Located upstairs, the private, primary suite is a true retreat, offering a spa-inspired bath and a custom walk-in closet. Incredible loft area off primary bedroom is an ideal offie space. This home delivers the perfect marriage of architectural integrity, designer interiors, and resort-style outdoor living!
