Welcome to a truly one-of-a-kind custom estate set on 12.9 private acres, thoughtfully designed for exceptional energy efficiency and striking architectural presence. Inspired by the strength and character of a 16th-century solid block castle, this remarkable residence immediately commands attention. Arrive through the private setting and step inside the grand entry, where a 2-inch thick solid Brazilian mahogany front door opens to a marble-floored enclosed vestibule wrapped in custom ironwork creating both an unforgettable first impression and intentional protection from the elements. Inside soaring 20-foot ceilings elevate the living room, anchored by a dramatic masonry fireplace that rises from the basement through three levels, forming a stunning architectural focal point. Custom gothic argon-filled windows flood the space with natural light, while intricate ironwork balcony and porch enclosures and detailed trim work showcase craftsmanship throughout. The kitchen is beautifully appointed with cherry cabinetry, ebony and silver countertops, and striking Blue Pearl granite flooring imported from Italy offering both elegance and durability. The spacious layout includes 5 bedrooms, 3 full baths, and a walkout basement, providing flexibility for guests, multi-generational living, or recreation. Comfort is prioritized with in-floor heating in the kitchen and exterior porch, four-zone radiator heating, an outdoor wood/coal boiler, and backup generator support for added energy independence. Step outside to experience the lifestyle this property offers: a 20x25 wrap-around deck, private trails throughout the acreage, and established fruit trees. The impressive outbuildings include a 30x48 pole barn with concrete floor, electric and water, feed barn with lean-tos, and chicken coop. This is more than a home it is a private estate designed with intention, strength, and enduring character. Schedule your showing today!
