Privately situated beyond a gated entrance at the end of an established enclave, 15325 Masonwood Drive is a country estate set on 37.8 acres of pasture, mature woods, and thoughtfully designed amenities in one of the Capital Region's most peaceful settings. Spanning approximately 18,400 square feet across a main residence and detached guest quarters, the property combines generous living spaces, extensive recreational amenities, and a rare sense of privacy in the heart of Darnestown. A long private drive winds through fully fenced grounds before arriving at a motor court. Double staircases frame the entrance, while carved wooden front doors open to an entry vestibule with illuminated art niches. Beyond, a marble foyer features a sweeping staircase and Baccarat chandelier. Designed to accommodate both large-scale entertaining and everyday living, the main level features 12-foot ceilings with tray and vaulted details throughout. Formal living and dining rooms flank the foyer in a traditional center-hall layout, while a coffered-ceiling family room provides a more relaxed gathering space. At the center of the home is a fully renovated chef's kitchen equipped with Thermador appliances and Sub-Zero refrigeration. Contemporary in design, the space features European-style cabinetry, a waterfall island, and recessed lighting. An adjoining breakfast area overlooks the surrounding grounds. Six bedrooms are located on the main level, including a newly created primary suite with a renovated bath. An additional primary suite occupies the upper level, offering privacy, motorized blinds, and views across the property. The lower level introduces an extensive collection of recreational amenities. A ballroom serves as the centerpiece of the entertaining spaces and is complemented by a temperature-controlled wine cellar, theater room, fitness center, sauna, steam shower, an additional bedroom, and expansive walkout living areas. Covered outdoor spaces with integrated gas lines for grilling provide a seamless connection to the grounds beyond. The outdoor amenities are among the estate's defining features. A private 9-hole golf course winds through the landscape, accompanied by a heated in-ground pool, tennis and basketball sport court, and an outdoor kitchen and bar pavilion with a grilling station, ice maker, and beverage refrigeration. Terraces and open lawn areas create ample opportunities for entertaining while preserving the property's sense of seclusion. A detached two-car garage includes a fully equipped guest apartment above with living areas, a kitchen, and en-suite accommodations. The lower level has been renovated to include an additional kitchen, two dens, a full bath, laundry facilities, and flexible-use space well suited for guests, extended stays, or estate staff. Supporting the property are multi-zoned geothermal heating and cooling systems, updated septic infrastructure, and numerous recent mechanical improvements. Offering an uncommon combination of acreage, amenities, and privacy, 15325 Masonwood Drive presents a distinctive estate opportunity in one of Montgomery County's most scenic settings.
