Upstairs, the luxurious primary suite showcases French doors leading to a private balcony, a spacious lounge or office area framed with windows, a generous walk-in closet, and a spa-like bathroom with a dual vanity, walk-in shower, and soaking tub surrounded by windows showcasing breathtaking views. Two additional bedrooms and a shared bathroom complete the upper level.
Outdoors, you’ll find a spacious patio and turf area designed for entertaining and relaxation. The expansive driveway offers ample space for RV, boat, or oversized vehicle parking, while a large metal shop provides endless possibilities for storage, hobbies, or projects.
