About This Property

Back on the market after massive price reduction! Nestled on over 13 acres of rolling, white-fenced countryside in sought-after Sandy Spring, 1301 Hennessy Terrace is a rare estate offering timeless architecture, refined interiors, and extraordinary grounds - all within minutes of Olney and major commuter routes.
A long, sweeping drive delivers you to a stately columned facade with classic symmetry and a brick walkway that sets the tone from the moment you arrive. Inside, the foyer opens to a sophisticated living room with rich statement walls - ideal as a music room, sitting room, or private office - and a formal dining room bathed in light from plantation-shuttered windows.
The family room anchors the home with a stone fireplace, custom built-ins, and French doors opening to the grounds. The gourmet kitchen impresses with white cabinetry, quartz countertops, a large center island, and striking gold lantern pendants. A sunny breakfast area overlooks the lawn, while a butler's pantry and wine nook serve the discerning host. The main-level primary suite is a true retreat with a fireplace, spa-style bath, and generous walk-in closet.
Upstairs, five additional bedrooms, skylit bathrooms, and a spacious bonus room - ideal as a media lounge, playroom, or flex space - offer comfort and versatility for family and guests alike. The expansive basement adds 7,000+ finished square feet of total living space with room for a gym, game room, recreation area, and office, plus a half bath.
Beyond the main residence, the estate delivers unmatched amenities: a climate-controlled 2-car garage for your collector cars, a 2,500+ sq ft barn with additional garage space for horses, hobbies, or storage, a basketball/tennis court, an outdoor terrace with fireplace perfect for cool evenings, and a hot tub set within your own private oasis.
The opportunity expands further with the potential for 2 additional buildable lots zoned R-2, subject to county approval - a compelling investment for the visionary buyer.
Served by Sherwood Elementary, William Farquhar Middle, and Blake High School.
