10519 ZION Dr

Welcome to 10519 Zion Rd — a one-of-a-kind, architect-designed modern residence where intentional design, superior infrastructure, and refined finishes converge. Fully reimagined by an owner-architect/interior designer and engineer team in consultation with AIA award-winning architect Randall Mars and acclaimed landscape architect Tom Mannion, this home underwent a comprehensive renovation—expanding the footprint by over 500 sq ft while reconfiguring the interior and upgrading every major system. This is not simply a renovation—it is a reinvention.
Clean modern lines meet warm, curated materials throughout. The dramatic entry features backlit, bookmatched natural gold onyx slabs, setting a sophisticated tone. Wide-plank hardwoods, slate, limestone, and designer carpet tile flow seamlessly across both levels, while radiant heated floors in the kitchen, family room, and upper-level primary bath add quiet luxury. Custom 1-3/8" bolection birch bookmatched veneer doors—many nearly 8 feet tall—complement maple cabinetry throughout. Bespoke millwork, custom casings, and thoughtfully layered lighting with Lutron dimmers create a warm, architectural ambiance.
The kitchen is sculptural and highly functional, with custom maple cabinetry, glass tile backsplash, honed poured-in-place concrete countertops, and commercial-grade GE Monogram appliances, including a six-burner gas cooktop, built-in 48" refrigerator, double convection wall ovens, and dishwasher. A beverage station features a bar sink, beverage refrigerator, 51-bottle wine cooler, and high-capacity undercounter ice maker. The living area’s gas fireplace, framed by honed Pennsylvania bluestone, echoes the home’s concrete design elements.
The bedroom layout offers flexibility and privacy. The upper-level primary suite is a true retreat with a custom walk-in closet and spa-caliber bath, including a digitally controlled steam shower with body sprays and Bluetooth audio, limestone floors and bench, chromatherapy soaking tub, maple cabinetry, and designer lighting. Two secondary bedrooms share a beautifully finished hall bath. A second-floor laundry with Electrolux steam washer and dryer enhances everyday convenience.
The main level also features a second primary suite with private exterior access—ideal for guests, multigenerational living, or a private office. This suite includes a walk-in shower with rainfall and handheld sprays, limestone flooring, and a custom artisan vanity with concrete countertop.
Behind the walls, every system was replaced or upgraded, including mechanical, electrical, and plumbing infrastructure. The home features a two-zone HVAC system, whole-house humidifier, UV air purification, smart thermostats, two tankless water heaters, dual 200-amp panels, and Weathershield wood insulated windows.
The exterior combines cedar and mahogany siding, freshly stained and painted in 2025, with a striking mahogany pivot front door. The widened concrete driveway includes an integrated French drain; Pennsylvania bluestone walkways and patios, Mexican river rock accents, and professional landscaping demonstrate a balance of beauty and function. The two-car garage was redesigned with custom storage, and the cedar board-on-board fence encloses a meticulously maintained yard with annual arborist care.
Located in Bonnie Brae, the home offers access to Sideburn Run Community Pool, Monticello Park, Woodglen Lake, Burke Lake Park, Royal Lake Park, Fountainhead Regional Park, and nearby trails including Pohick Valley Stream Valley and South Run Trail, along with Burke VRE and major commuter routes.
10519 Zion Rd is a rare architectural offering—where design integrity, technical sophistication, and enduring craftsmanship converge. For the discerning buyer seeking a truly custom modern home built with intention and maintained with precision, this residence stands apart.
