None of these is an appraisal. Your lender orders one of those once an offer is accepted, and it is the figure that decides how much they will actually lend.
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.
