On a secluded perch high on a hill with an unsurpassed sweeping southwestern view out across the forks of the Brandywine, sits the Foster Nix House - so named for the home's builder and first resident, one of the leading scientists involved in the Manhattan Project. Great genius that he was, Foster Nix built himself the perfect country home. Designed in the very popular "Midcentury modern" architectural style, and exceedingly well built, this four bedroom, 3.1 bath home with thick, poured concrete walls faced in natural stone and a slate roof, is set on 12.8 gorgeous acres. The well laid out home includes a large Living Room, a Family Room/Library, both with fireplaces, and a Dining Room - all with plenty of glass to highlight the incredible views. The eat-in Kitchen features high-end appliances and is adjacent to the home's laundry, mudroom area, and the staircase leading to a wonderful guest suite with a bedroom, sitting/dressing room, and full bath. Rounding out the main level is a spacious Master Suite with a recently remodeled bath along with plenty of fabulous closet and built-in storage space. Upstairs are two additional bedrooms and a full bath. Outside is a patio with a koi pond that is the perfect place to entertain and is set to take great advantage of the long views. The home's utilities include a geothermal heating system to supply the radiant heat that is augmented by a newer, high-end Buderus oil furnace. For the car lover, or those in need of abundant storage space, the property includes a two car attached garage, and a large four car detached garage. The charming two bedroom cottage, set away from the house, has its own private outdoor area overlooking the fields and is perfect for long-term guests, extended family, rental income, a home office and more. For the equestrian, the well planned barn includes six large stalls, a wash stall, a large heated tack room and plenty of hay storage above. There are also two fenced pastures and an outdoor riding arena. For the gardener, the property is rounded out with a gardening house and attached green house. The property is bordered by large farms that are protected by conservation easements. This is a fantastic country property for the buyer looking for serenity as well as a convenient location near to West Chester but within Unionville-Chadds Ford School District.
