Tucked at the end of a tree-lined cul-de-sac, 7605 Arnet Lane makes a commanding impression—three above-grade stories wrapped in smooth stucco and crowned with red clay Ludowici tiles, blending timeless elegance with total privacy. A stately portico frames a 10-foot Sapele mahogany door with horizontal paneling—an architectural motif echoed throughout the home’s custom interior doors and garage fronts. High-set glass brings in natural light while preserving privacy. A multi-point locking system and video intercom ensure security. Inside, an 18-foot foyer with a sweeping illuminated staircase and paneled walls sets a dramatic tone. The main level features a guest suite with Marvin windows, walk-in closet, and Porcelanosa bath with heated floors. A fitness center, pantry, utility room, and full bath add functional luxury—plus a pre-built elevator shaft. Behind a barn door, a professional home cinema—concrete-reinforced and climate-controlled—offers comfort and storm protection. Upstairs, a heated pool, cascading spa, and expansive Porcelanosa hardscaping define a serene courtyard sanctuary. Every room on this level and above overlooks the water feature and meadow-inspired landscaping through oversized Marvin windows. Nine-foot ceilings, tray detailing, and paneled shelving elevate the living and dining rooms. In the living room, a Haiku fan stirs the air, while barn doors open to a family room with a Wittus wood stove. Oversized glass doors provide seamless access to the terrace. A speakeasy-style wet bar—complete with Sub-Zero beverage and wine refrigerators, icemaker, and illuminated shelves—serves both indoor gatherings and poolside soirées. A nearby study with terrace access provides a tranquil work-from-home setting. A spiral staircase with steel railings (mirrored outside) leads to the third-floor loft. The Ferguson-designed kitchen features sleek cabinetry, granite counters, and elite appliances from Bosch, Wolf, and Sub-Zero—including the Pro 48 refrigerator. A prep sink on the island complements the main sink with a touchless faucet. The layout flows effortlessly to dining and the pool—ideal for entertaining. Another bedroom suite on this floor offers a tray ceiling, custom closet, and Porcelanosa bath with heated floors. The grand, book-lined staircase ascends to the primary suite, occupying its own wing. A sitting room opens to the bedroom beneath vaulted ceilings and a Haiku fan. French doors lead to a private terrace with a gas fireplace and heated Porcelanosa tile, overlooking the pool. The spa-like primary bath features heated Porcelanosa flooring, a floating double vanity, Victoria + Albert soaking tub, and dual walk-in dressing rooms. Two additional bedrooms offer Juliet balconies, vaulted ceilings, Haiku fans, ensuite Porcelanosa baths, and custom closets. A laundry room completes the floor. A heated driveway and retaining wall lead to a three-car garage with handcrafted doors. Inside, a climate-controlled, fire-suppressed showroom with polished concrete floors transforms car storage into a curated experience. This home is a true technological showcase. A Nice automation system manages 16 audio zones, Lutron lighting, security, and surveillance—controlled via in-wall iPads and mobile devices. Additional infrastructure includes a 16-zone geothermal HVAC system, ERV for fresh air, humidifier, Generac generator, QuietRock soundproofing, and three 200-amp panels. Deep-set Marvin windows and Lutron blinds enhance comfort and privacy. All systems—including pool, security, and lighting—are fully smart-enabled. Just minutes from River Road, the Beltway, top schools, country clubs, and DC’s cultural offerings—7605 Arnet Lane is not just a home, but a statement of modern luxury redefined.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
