Experience elevated living in this to-be-constructed BCN custom estate in Country Club Hills, one of North Arlington's most coveted enclaves, just minutes from Washington, DC, Tysons, and Clarendon. Perfectly positioned on a quiet, tree-lined cul-de-sac, 3500 N. Abingdon Street will embody refined architecture and bespoke finishes. Spanning nearly 8,000 square feet, this 6 bedroom, 6bath, 2 half bath residence showcases an open and airy layout with soaring ceilings, expansive windows, and a two-story vaulted family room anchored by a striking stone fireplace. A grand foyer introduces a showcase dining room with floor-to-ceiling windows, while across the hall, a private study is tucked away with custom built-ins offering an inspired home workspace. A formal parlor, complete with French doors, built-ins, and a fireplace, connects gracefully to the main living area-creating an elegant yet versatile flow ideal for gatherings large or small. This space of the home provides flexibility for those buyers needing a main level bedroom, dual study or main level playroom space. The gourmet kitchen is where design and livability unite, featuring an oversized island, 48-inch range, butler's pantry, and handcrafted cabinetry tailored for both style and function. Tucked discreetly away from the home's main entertaining spaces, the hardworking mudroom provides seamless access to the three-car garage and private backyard. Outfitted with a lovely locker system, secondary powder room, and back stairway to the upper level, it's a beautifully organized transition zone that balances refinement and practicality. Throughout the home, wide-plank white-oak floors, custom millwork, and thoughtfully curated finishes create moments that invite pause-each detail a testament to the grace and intention behind every decision. Upstairs, the primary suite retreat impresses with a vaulted ceiling, spa-like bath with freestanding soaking tub, and expansive dual walk-in closets. Each of the four additional bedrooms features its own ensuite bath and walk-in closet. At the top of the striking stairhall, a sunlit family lounge-finished with custom bookcases-serves as a serene point of connection, perfect for quiet mornings or unwinding at day's end. The lower level delivers flexible luxury: a light-filled recreation room opening to the grotto lounge and covered patio, a wellness room with optional sauna, a bar with wine cellar, and a true home theater or storage area. A private guest suite provides comfort and independence for long-term guests or an au pair. An additional powder room on this level enhances the practicality of the space. Outdoors, enjoy multiple entertaining spaces, including a screened porch, elevated deck, and covered grotto lounge, all overlooking the 0.38-acre landscaped backyard-a setting ideal for a pool, spa, or two-story pool house/garage combination. Constructed with high-efficiency systems, Low-E windows, and advanced HVAC design, this home delivers both sustainability and superior comfort. Floor plan has been designed to accommodate an elevator. Finish options are endless but can also be hands off, trusting the BCN team who has perfected this level of luxury home. Fall 2026 Completion.
