About This Home

As of October 2025

Nestled on over 13 acres of rolling lawn in Sandy Spring, 1301 Hennessy Terrace is a rare blend of timeless architecture, refined interiors, and exceptional grounds. With more than 5,000 finished square feet and 12,000+ square feet including outbuildings, this residence is designed for both gracious entertaining and comfortable everyday living. This home comes with potential for 2 additional buildable lots zoned R2, subject to county approval!

A long, sweeping drive leads you past white-fenced fields to a stately front facade with classic symmetry, brick walkway, and columned porch. From the moment you arrive, the home exudes warmth and elegance, perfectly balanced by the privacy of its expansive grounds.

Inside, the foyer opens to a sophisticated living room with rich blue walls, perfect as a music, sitting room or future office and a formal dining room bathed in light from plantation-shuttered windows. The heart of the home is the family room, where a stone fireplace, custom built-ins, and French doors invite both intimate evenings and lively gatherings. The gourmet kitchen shines with white cabinetry, quartz counters, a large center island, and striking gold lantern pendants. A sunny breakfast area overlooks the lawn, while a butler’s pantry and wine nook add touches of convenience.The main-level primary suite offers a true retreat, complete with fireplace, spa-style bath, and a walk-in closet.

Upstairs, find five additional bedrooms and three full bathrooms — each bedroom thoughtfully designed with natural light and ample storage. A spacious bonus room serves as a media lounge or playroom, ensuring flexibility for modern living. Skylit bathrooms add charm and brightness to the second level.

The lower level is expansive and versatile with home to a future game room, family room, recreation area, gym and office with a half bathroom:

Beyond the main home, the property offers unmatched amenities, a 2,500+ sqft barn with a 2 car garage for horses, hobbies, storage and more! The yard is complemented with a basketball/tennis asphalt court, outdoor terrace featuring a lovely fireplace for those fall and winter nights and a hot tub to enjoy while you soak in your private oasis.

Located just minutes from Olney and commuter routes, this estate provides country serenity with suburban convenience. Whether it’s coffee on the porch, dinners on the covered patio, or games on the sports area, life here flows seamlessly from indoors to out.

1301 Hennessy Terrace is more than a home — it’s an estate, a retreat, and a lifestyle.
