Recent upgrades include new carpeting, custom stonework, dual aquariums and luxury bidet installation. The 3,200-square-foot, 3-bedroom guest house includes a private office and separate outbuilding, while the farmhouse boasts a detached garage, creating exceptional flexibility for collectors, hobbyists, equestrian pursuits or recreational storage.
