Majestically positioned upon eighty pristine acres within Clarksburg's most distinguished countryside enclave, this Frank Lloyd Wright-inspired architectural tour de force represents the pinnacle of luxury residential design. Approached through monitored gates and a winding driveway, this extraordinary five-bedroom, seven-bathroom estate exemplifies uncompromising craftsmanship, where the masterful fusion of Corten steel, cedar, and metallic exterior elements creates a striking modern silhouette set against a magnificent natural backdrop, enhanced by dramatic landscape lighting that elevates the estate's grandeur through twilight hours. The palatial interior reveals soaring eighteen-foot ceilings and resplendent marble floors, culminating in an open-concept masterpiece with polished concrete flooring and 12.5 ft. floor-to-ceiling windows framing the serene landscape. The Varenna Poliform kitchen impresses with a 20.5 ft. island, Sub-Zero and Wolf appliances, 11 ft. ceilings, and bespoke walnut cabinetry that flows with architectural harmony throughout. The lavish two-storey primary suite offers polished plaster walls, custom walnut built-ins, a marble ensuite with chronotherapy rain shower, and a private retreat lounge. Additional bedrooms include terraces or balconies, with two guest suites offering luxurious ensuites-one serving as a secondary primary with service bar. Entertainment abounds with a professional theatre, custom gym, and stunning two-storey lounge bar overlooking a 22 ft. infinity pool. A heated five-car garage and radiant flooring ensure year-round comfort. A separate two-storey guest house includes a full kitchen, loft bedroom, and soaring ceilings. A pristine barn provides premium equestrian facilities. Landscaped grounds feature a fire pit, hot tub, and pergola, all enhanced by elegant lighting. With Loree Forest nearby and a Generac generator, this estate blends architectural brilliance with modern sophistication.
