Rarely does a property of this caliber become available! Spanning 20 expansive acres just outside Thornbury and Clarksburg on Grey Rd. 13, this estate is a true gem. A newly paved, winding driveway leads you to a secluded residence that’s been meticulously designed for comfort and style. The 3000+ square-foot home features a gourmet kitchen equipped with stainless steel appliances, honed marble counter tops, terracotta floors, and a fireplace surrounded by built-in cabinetry. The main floor primary bedroom boasts a generous en-suite bathroom and a spacious walk-in closet. The great room impresses with its soaring ceilings and another elegant fireplace. Currently serving as a music room, the formal dining area also includes a built-in office cupboard. Upstairs, you'll find two generously sized bedrooms, while the lower level offers a large gym and sauna. Several walkouts lead to a stunning 16x32 saltwater pool and a pool house. The cement pad is perfect for skating in winter and doubles as a pickleball court in warmer months. An attached double garage provides convenient access to both the main floor and lower level, while a detached 4-car garage with in-floor heating offers ample vehicle storage. The upstairs bonus space is finished, ideal for guest accommodations. A second winding paved driveway leads to the equestrian area, which features a remarkable 4-stall barn with hydro, water, and a spray-foamed loft. There are two paddock areas with shelters and a riding ring. A charming bunkie with tiered decking overlooks two picturesque ponds, and to complete this extraordinary property, the Beaver River gracefully flows along the entire western boundary!
