Swimming Pen Farm - the original estate on ±70 private acres, where serenity meets possibility. At the end of a long, tree-lined drive sits a rare Loudoun opportunity that simply can't be recreated: the original, lovingly-maintained residence - a cherished one-owner home before its sale - now offered on ±70 acres of open pasture, mature woods, and a 5-acre spring-fed pond, with abundant wildlife and recreational land to explore, roam, and enjoy. Enjoy true one-level living, with walls of glass framing sweeping field-and-tree-line views from nearly every room. At the heart of the home, a custom-designed gourmet kitchen with a large center island, double ovens, a warming drawer, and two dishwashers - a dream for the avid cook and effortless for entertaining. A light-filled great room made for gathering, a fireside living room, and a custom built-in library. The spacious primary suite is a private wing all its own - complete with a fireplace, a dedicated private office, and an adjoining flex room, the perfect owner's retreat for work, rest, and everything in between. A flexible 4-to-5 bedroom layout, a 4-car garage, and a pole barn ready for animals, hobbies, equipment, or toys. A covered porch overlooks it all - with room to roam in every direction. Here you'll find the best of both worlds: the privacy and space of the country, with a new luxury community taking shape just beyond your tree line. Ideally set in coveted Western Loudoun - surrounded by award-winning wineries, craft breweries, and farm venues, with antique trails, the Potomac River, charming small towns, and local restaurants all close at hand, plus easy access to shopping and Dulles International Airport. No matter the direction, there's something for everyone. Bring your vision - private escape, gentleman's farmette, or gathering compound - a place to slow down and savor the daily. Land like this, in this location, does not come again.***Currently in Land Use****Considered a Home Preservation Lot with a Pen Space Easement.
