16420 BLACK ROCK ROAD, GERMANTOWN, MD 20874 - Martin Millner Real Estate

$1,595,000

Rebuilt from the rafters up in 2008 and inspired by a Sonoma California estate, this Darnestown home blends solid construction with thoughtful design and everyday comfort. Set on one of the area's most scenic streets, the 2.5 acre property offers privacy, mature trees, and a peaceful setting that feels tucked… Read More away while still close to everything. A 50-year architectural shingle roof, whole-house central vacuum, and energy-efficient systems add lasting value and ease. The exterior pairs stonework with a welcoming front porch and clean, classic lines. Out back, the home opens up to a series of outdoor living spaces designed to be used year-round, including expansive decks and patios, a built-in kitchen, and a covered stone-column lanai with a fireplace. Inside, the layout is both spacious and practical, with over 7,000 square feet finished across three levels. Natural light fills the home through custom windows, and French doors along the main level create a strong connection to the outdoors. The kitchen is the centerpiece, built for serious cooking and entertaining with a full Viking suite, oversized refrigerator, dual gas ovens, additional electric oven, Miele steam oven, gas griddle, wok cooktop, and a 150-bottle wine fridge. A separate butler's pantry adds a second dishwasher, ice maker, coffee system, warming drawers, and a full walk in pantry adds extra storage. The main level includes multiple gathering spaces, a formal dining room, and a flexible room that works well as an office, den, or playroom. A private bedroom suite with its own patio and full bath adds convenience, along with two powder rooms and a well-designed mudroom. Upstairs, the primary suite is set up as a true retreat with a private balcony, fireplace, beverage station, soaking tub, walk-in shower, and dual wardrobe rooms that connect directly to the laundry. Two additional bedrooms, two full baths, an office nook, a large laundry room and a loft area complete the upper level. The walkout lower level is finished for entertaining, with a custom bar, 400+ bottle wine cellar, gym, full bath, and media space. Heated floors and a dedicated towel area lead directly out to the hot tub. The outdoor setup continues the same level of detail, with a covered veranda, wood-burning fireplace, two built in heat lamps, built-in Viking grill, GE Monogram refrigerator and sink. Lighting throughout the landscape and exterior creates a warm, inviting feel in the evening. A rustic barn and fenced yard add character and usable space. Additional features include a 3-car garage, 100-amp generator, Brazilian cherry hardwood floors, three hot water heaters, and extra storage. Conveniently located 5 miles from River Road with quick access to the Beltway, and close to Seneca Creek Park and nearby orchards and wineries, this home offers a rare mix of privacy, convenience, and access to some of the area's best outdoor and local spots.
