Spectacular country property in beautiful Willistown Township, Radnor Hunt. Located on a “Scenic Roadway”, Black Sheep Farm offers bucolic country living with over 17 breathtaking acres, a manor home, banked barn, carriage house, outbuildings, and fenced pastures. Over the past several years, this property has been home to horses, goats, and “Clementine” the donkey. Most recently, Black Sheep Farm has undertaken a successful breeding program for the Valais Blacknose sheep, a Heritage breed from Switzerland. The centerpiece of the property begins with the original farmhouse, built in 1780. The former owners expanded the house in 1998 and the current owners engaged renowned architect Warren Claytor and respected Griffiths Construction to add another 2000 sq ft addition in 2011. The carefully planned additions and renovations have maintained the historic features and beauty of the original farmhouse, while updating the home for today’s living. An open floor plan encompasses a family room with impressive architectural details, including a vaulted, beamed ceiling, cherry built-ins, and fireplace. The gourmet kitchen, featuring custom cherry cabinetry, high-end appliances, and abundant counter space, opens to the sun-drenched breakfast room. The beautiful, stone facade and large front porch welcomes guests and family into the original part of the home. The gracious living room highlights the historic charm, with fireplace, painted floors, and curved, deep windowsills. A second family room in the most recent addition features stone walls, a kitchenette, fireplace, and gorgeous views. Spacious bedrooms, renovated baths with limestone counters, beautiful hardwood and stone floors, elevator, flagstone patios, and porches make this a truly unique and special home. The fabulous saltwater pool with waterfall is perfectly situated for privacy, relaxation, and enjoyment of the beautiful property. A one-bedroom carriage home provides the perfect space for long-term guests or family. The 4-stall stone banked barn includes an office with full bath and a renovated “Party Barn” on the upper level. Additional buildings include a 2-stall pony barn, chicken coop with run, turn-out sheds, and a stall and feed room in the upper pasture. The property has been a working farm for the past several years, but the animals are being removed so the new owner can bring their own vision and ideas to the property. Whether as a working farm or a peaceful and private country estate, Black Sheep Farm is a truly unique, exceptional property! Property has conservation easement with Willistown Conservation Trust.
