Gated 13.1-acre estate in the heart of Loudoun County’s horse and wine country. Stone gate pillars open to a 1,000-foot drive that curves across open pasture, past the 3-stall barn, to the residence, set high and back for privacy and sweeping views of the creek, rolling countryside and mountains beyond. Built in 1999 with approximately 5,650 finished square feet, the home features a fieldstone front with stucco and a stone skirt on the remaining three sides, copper gutters and downspouts, extensive stone hardscape and mature landscaping. Inside are nine-foot-plus ceilings and hardwood floors throughout the main and upper levels, with no carpet. Gas fireplaces warm the Great Room and Primary Suite, and an upstairs family room overlooks the pool. In all: five bedrooms, four full and two half baths, two full kitchens, a laundry room and a second washer/dryer on the lower level. The walkout lower level is a complete apartment with a private entrance and full-size windows. It has a kitchen with island, a living room, a gym, a powder room, and a bedroom with walk-in closet, ensuite full bath and its own stacked washer/dryer in a lighted closet. Then dim the lights in the professional theater, with its 3D direct-view screen, 12.1 surround sound, dual 1,000-watt subwoofers, tiered seating and a popcorn alcove. Outdoors, a multi-level deck steps down to a sunken hot tub and a secluded gunite pool terrace with waterfall, framed by stone walls and mature evergreens. The barn has electric and water, a hay room and a tack room, and is joined by a run-in shed, an equipment shed/workshop with electric and water, multiple fenced pastures and two creeks.
