A masterpiece of design and craftsmanship on one of Darnestown’s most historic and picturesque streets. This exceptional estate sits on a premium lot offering unmatched privacy, views, and a natural setting that seamlessly blends luxury with tranquility. Inspired by a Sonoma, California estate, the home is nestled among mature trees with carefully designed landscaping to enhance the natural surroundings. Designed with indoor-outdoor living in mind, six French doors on the main level open to expansive decks, patios, an outdoor kitchen, and a stunning stone-column lanai with a fireplace. This home offers over 7,000 square feet of exquisite living space with custom finishes, natural materials, and energy-efficient systems throughout. The elegant stone front and welcoming porch set the tone for the refined interior, where custom windows flood the space with natural light. Inside, you'll find two luxurious primary suites, generous secondary bedrooms, multiple sitting areas, and flexible spaces for work or play. At the heart of the home is a chef’s kitchen equipped with top-tier Viking appliances, including an oversized refrigerator, 150-bottle wine fridge, warming drawer, dual gas ovens, an electric oven, Miele steam oven, gas griddle, and a dedicated wok cooktop. The adjacent butler’s pantry includes a second dishwasher, icemaker, Miele coffee machine, cup warmer, dish warmer, and ample space for glassware and entertaining essentials. The breakfast room features a double-sided fireplace and comfortably seats six or more. The main level also features a spacious sitting room, family room, formal dining room, and a versatile flex space ideal for a home office, den, or playroom. A main-level bedroom suite includes its own patio and en suite bath. Two well-placed powder rooms and a large mudroom further support functional daily living. Upstairs, the primary suite is a private retreat with its own balcony, fireplace, coffee and beverage station, Japanese soaking tub, standing shower, and dual wardrobe rooms connected to the laundry room. Two additional bedrooms, two full baths, and a cozy loft area complete this level. The recently finished walkout lower level is perfect for entertaining, featuring a custom bar, 400+ bottle wine cellar, gym, full bath, and media space. Heated flooring and a designated towel/robe area make for an easy transition to the outdoor hot tub, where you'll enjoy serene views year-round. Step outside to enjoy true resort-style living: a covered veranda with recessed lighting and ceiling fans, a wood-burning outdoor fireplace, and a fully equipped built-in kitchen with Viking 53” grill, GE Monogram fridge, and sink. Landscape and architectural lighting create an enchanting ambiance after sunset. A rustic barn, fenced backyard, and geothermal heating/cooling system further elevate this home's appeal. Additional features include a 3-car garage, 100-amp generator, Brazilian cherry hardwood floors, three hot water heaters, extra storage and crawlspace. Located near I-270, upscale dining, shopping, Seneca Creek Greenway Trail, and the MD SoccerPlex, this rare offering combines timeless sophistication with effortless luxury, privacy, and convenience.
