Description

Architectural Integrity Meets Modern Masterpiece. Sophisticated craftsmanship and historic soul converge in this three-year-old custom estate situated on 30 +/- private acres. You are welcomed by the 50’ x 10’ stamped and stained covered front porch that features a second story porch also. The home is defined by 9-foot ceilings across all three levels and built with rare, historic reclaimed mortise and tenon barn beams, this residence offers a rare blend of rustic heritage and contemporary luxury. The main level serves as the home’s heartbeat, with an open floor plan featuring an expansive great room anchored by a floor-to-ceiling stone fireplace and refined wood shiplap walls. Separate dining area and large ½ bath for the guests. The culinary kitchen boasts: quartz-surfaced countertops, oversized island with seating, a classic farm sink, and custom cabinetry. There is a private large laundry room and a walk in pantry in the entry to the 3 car oversized garage. Enjoy your private back deck, partially covered, walks to the garage and stairway to lower level, overlooking your private 30 acres. The primary sanctuary is a masterclass in comfort, featuring a custom walk-in closet with integrated cabinetry, a vintage-style clawfoot tub with separate rainfall shower. Ascend to the upper level to find a versatile family lounge with a dedicated cinema wall and projector, a private executive office, and 2 generous bedrooms featuring a secret passageway for a touch of whimsy. Lower level is partially finished and ready for you to make it your own. Engineered for the future, the estate features a 400-amp electrical service with a 100-amp sub-feed for a future workshop, solar-ready infrastructure, central vac system and a climate-controlled 500-square-foot reinforced concrete vault. The 30x40 side entry garage offers 10x10 doors, man-door to deck and a dedicated dog wash station, complemented by an extra 14-foot height carport. Clad in Hardie Board siding and crowned with a permanent metal roof, this estate is not just a home—it is a legacy in the making. Part of the property is in De Soto Sch. and part in Kingston Sch. sellers have been told you can contact either regarding attendance.
