A masterpiece of refined living, this magnificent all-brick custom home commands a breathtaking 5-acre private retreat backing to serene woodlands and parkland — an extraordinary sanctuary where natural beauty and elegant design meet. Perfectly positioned with effortless access to Braddock Road and Fairfax County Parkway, this coveted address delivers the best of both worlds: tranquil seclusion and seamless connectivity. The celebrated Queensbury Model by Keystone Builders impresses at every turn with soaring 10' main-floor ceilings, a grand 2-story family room framed by spectacular wooded vistas, dual hardwood staircases, and a sun-drenched rear solarium. The exquisitely reimagined gourmet kitchen is a culinary statement — anchored by a 48" Thermador professional cooktop, double oven, iconic SubZero refrigerator, and a dramatic quartz waterfall island worthy of the finest entertaining. Over $250K in curated upgrades elevate every corner: gleaming refinished hardwood floors, designer lighting, bespoke plantation shutters, artisan custom millwork, and a breathtaking floor-to-ceiling fireplace as the living room's crown jewel. The fully permitted walkout lower level offers resort-style living with a chic bar, private gym, and spa-inspired bath. Outside, a generous deck, custom stone patio, outdoor fireplace, and tranquil pond create an unrivaled al fresco escape. Meticulously upgraded and flawlessly move-in ready — this is the one.
