About this home

Welcome to this beautiful Colonial located in the heart of Biltmore Shores, just steps from the Biltmore Beach Club. From the moment you enter, you’re greeted by a dramatic two-story foyer with soaring ceilings and an open staircase that creates a warm and inviting first impression. Hardwood floors flow throughout the home, complemented by an open and airy layout designed for both everyday living and entertaining. The updated kitchen features granite countertops and opens into comfortable living spaces, including a cozy wood-burning stove, French doors leading to a den and first-floor office, and plenty of natural light throughout. The home offers four spacious bedrooms, one full bath on the main level, and a second full bath upstairs, along with the convenience of second-floor laundry located near the bedrooms. Plumbing is already in place in the primary bedroom, offering future potential for a private en-suite bath. Outside, enjoy a detached garage and private backyard perfect for entertaining, relaxing, and enjoying all that Biltmore Shores has to offer. A rare opportunity to own a home that blends charm, functionality, and an unbeatable location. Flood Zone X.
