About this home
This North Potomac home has hosted a full life, and the guest list keeps coming back. Not occasionally, but for countless meals, everyday celebrations, long weekends, and visitors in town. The vaulted great room is where that life gathers. Ceilings lift to exposed beams and a full wall of windows turns the yard into the view from nearly every seat, making it the room the rest of the house defers to and the one that sets the pace for the evening. What makes the hosting sustainable is the privacy built in behind it. The main entry foyer opens to a formal dining room, a separate formal living room, and a main-level home office, so the working day and the dinner party never have to share a footprint. Off the kitchen, a morning room looks out over the pool, which is where most days here start. A walk-in pantry sits off the laundry room, the kind of detail that only reveals its value when the house is full. The primary suite holds two closets, including a custom walk-in. Hardwood and ceramic tile floors run throughout, with carpet conveniently in 2 bedrooms. The deck is the main stage. It spans wide enough for a band, a dance floor, and a sit-down dinner at once, and a built-in outdoor prep station with its own sink means the host never has to disappear inside to keep things moving. Below it, the in-ground pool reads as a continuation of the deck rather than a separate destination, stepping down into the yard, and a lower terraced section of the backyard opens further still for games and recreation. The house handles a weekend guest and a long-term one equally well. Rooms stay private, spaces stay connected, and there is no need to choose between them on a given evening. The unfinished basement carries infrastructure already in place for whatever comes next, serving in the meantime as generous storage and hobby space. Some homes are designed for entertaining. This one has the history to prove it. 12321 Triple Crown Road truly stands apart as a rare combination of scale, flow, and genuine outdoor living. Open house Saturday, October 10, 1 to 4pm.
Mountain View Estates, located between Darnestown Road (MD-28) and Muddy Branch Road, is a residential and wooded North Potomac neighborhood with curving cul-de-sacs and generous yards. The neighborhood’s character concentrates around the Darnestown Rd–Muddy Branch Rd crossroads, where commuter traffic meets a low-key strip of local storefronts and everyday errands. Nearby, Kentlands Market Square adds a walkable dose of indie dining and retail, anchored by places like The Kentlands Mansion and the Arts Barn. Architecture leans toward late-20th-century colonials and brick-front traditionals set back behind mature trees. Green space defines the rhythm, with Muddy Branch Stream Valley Park and the C&O Canal towpath shaping weekend routes. The setting feels tucked from commercial corridors while still tied to Gaithersburg’s cultural calendar.
