A glass-and-light modern masterpiece, this custom residence by Potomac Custom Homes spans nearly 10,000 finished square feet on a quiet cul-de-sac in The Reserves at Pinecrest, privately backing to protected Fairfax County parkland. Expansive walls of glass and dramatic vertical spaces set an unforgettable tone, anchored by soaring 20-ft ceilings in the main living area and the primary sitting room, with 10-ft ceilings throughout the rest of the home. A custom floating staircase wrapped in fully enclosed glass railings rises through every level, while large-format Roberto Cavalli porcelain flooring and radiant heat bring warmth and cohesion to the main living spaces. At the heart of the home, a chef's kitchen is designed to impress: custom Italian UNICA cabinetry, 3-inch DEKTON Aura waterfall countertops, a professional GE Monogram appliance suite with induction range, and an expansive island built for gathering. GROHE designer fixtures and copper supply lines reflect a commitment to quality throughout. Designed for entertaining and everyday escape, the finished lower level delivers a dedicated home theater, a golf simulator room with an $80K build-out, and a private gym, with theater seating, projector and screen, and gym equipment all conveying. Outdoor living rivals a private resort. A saltwater fiberglass pool with Pentair heating, LED lighting, a decorative waterfall, and an automatic cover is surrounded by an expansive patio with a built-in Weber gas grill, outdoor refrigerator, and integrated storage. Upstairs, the primary suite opens to a private balcony retreat with a hot tub overlooking the trees. Smart and built to last, the home features Control4 whole-home automation, a hardwired security system, a full-house Generac backup generator, three-zone Carrier HVAC, and app-controlled Rachio smart irrigation. A spacious 4-car garage with 8-ft doors, epoxy floors, and custom storage, plus a mudroom with a built-in pet-washing station, complete the offering. Minutes to I-495, I-395, Route 236, Route 7, and Braddock Road, with parks, golf courses, shopping, and dining close by, this is contemporary luxury with a true sense of retreat in the heart of Northern Virginia.
