Two deep wells provide ample water for the estate, while two detached four-car garages offer abundant space for a car collection, toys, or storage. Above one garage, a beautifully finished 988 sq. ft. guest apartment stands as its own fortress, constructed with 12-inch-thick concrete block walls and featuring a full kitchen, living area, bedroom, bath, and a private deckperfect for hosting guests or generating rental income. Expansive balconies overlook the grounds, offering panoramic views and moments of serene reflection.
