About This Home

6140 County Road 315c

Welcome to your private kingdom - a majestic, custom-designed estate nestled on 4 manicured acres, complete with a serene stocked pond and surrounded by a stately brick wall with an iron gate. This fortress-like masterpiece evokes the grandeur of a modern-day castle, crafted with unmatched precision and an unwavering commitment to quality by its original owner. At the heart of the estate lies a 4-bedroom, 4-bathroom main residence (5,170 sq ft), artfully designed with soaring ceilings, intricate brick archways, and a striking fireplace centerpiece that anchors the grand living space. With two full kitchens and two laundry rooms - strategically placed both upstairs and down - this home effortlessly blends function with elegance. Every detail echoes a sense of permanence and luxury, from the 18-inch-thick, steel-reinforced exterior walls to the 6-inch solid concrete foundation and durable metal roof, secured with double-strapped trusses. Inside, reinforced concrete interior walls and layered high-efficiency insulation create a sanctuary of tranquility and resilience. A state-of-the-art 300-amp electrical system and whole-home surround sound ensure modern convenience within this timeless structure. Outdoors, discover a private resort built for royal-scale entertaining: a sparkling saltwater pool, two fully-equipped outdoor kitchens with dedicated pool bathroom, four BBQ pits, four outdoor showers, and a custom masonry fire pit. 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. The spacious bonus/game room and oversized bedrooms offer comfort and flexibility for both everyday living and grand-scale entertaining. This estate is not just a homeit's a legacy of strength, elegance, and timeless design. A rare opportunity to own a property that combines the fortified feel of a castle with the refined luxuries of a modern retreat.
