Some homes sit on their lots. This one was designed to become part of its setting. Built by noted Reston builder Warren Katz, 11424 Purple Beech Drive is a distinctive contemporary tucked beneath a canopy of mature trees, with seasonal views of Lake Thoreau, neighborhood lake access and a remarkably walkable South Reston location. The unconventional, angular floor plan reflects the character of Katz-built homes: contemporary lines, abundant natural light and rooms thoughtfully oriented toward the surrounding landscape. A welcoming foyer introduces the main level, where the kitchen, breakfast room, dining room and living room flow together across one side of the home. At the center, a circular free-standing fireplace creates a shared hearth between the living and dining spaces, and the background brick wall creates an efficient heat sink. Redesigned with cooking and entertaining in mind, the custom kitchen is both striking and exceptionally functional. Silestone countertops, hardwood flooring, and extensive cabinetry surround a large stainless steel farmhouse sink, secondary prep sink, and two disposals. Appliances include a Sub-Zero cabinet-depth refrigerator, DIVA induction cooktop with Wolf downdraft ventilation, a new built-in double/convection/microwave oven, a warming drawer, a steam oven, and a refrigerator. Pull-out shelving, specialized spice storage, a pantry with an Elfa organization system and professionally painted cabinetry complete the space. The opposite side of the main level includes a private office, powder room, oversized coat and storage closet with an Elfa system, and access to the two-car garage. Pocket doors, recessed lighting, hardwood flooring, custom built-ins, and Andersen windows appear throughout the house. Upstairs, the spacious primary suite is complemented by two additional bedrooms, including one with an en-suite bath and a large cedar-lined closet. The renovated primary bath offers the feel of a private spa, with heated tile floors, a skylight, custom teak dual-sink vanity and cabinetry, a stone soaking tub, and an oversized shower with body jets and electronic controls. Organized closets, additional hallway storage, attic access, and an upstairs laundry room add convenience. The expansive bonus room creates an entirely separate place to gather, work or host overnight guests. It features a wet bar, Murphy bed, projector and screen, making it equally suited for movie nights, a game room or flexible guest space. Outside, the setting becomes the experience. A screened porch with a tiled floor, skylights and ceiling fan opens to an expansive paver patio surrounded by mature trees and bamboo. Follow the garden paths to a tranquil water feature with a flowing stream, pond and footbridge, or settle near the outdoor fire-pit area beneath the trees. The 0.32-acre property backs to Reston common area, enhancing the sense of privacy and connection to nature. Major recent improvements include a new roof in 2026, newly resurfaced driveway, freshly painted interior, built-in oven in 2026, professionally painted kitchen cabinetry in 2024 and exterior painting approximately two years ago. The garage-door motors and operating mechanisms have also been replaced. All bathrooms have been updated throughout the years. From here, Lake Thoreau is part of daily life. Carry a kayak or paddleboard to the neighborhood lake access, follow the walking trail around the water. South Lakes Village Center is also within walking distance, with Reds Table, Caf Sano, Starbucks, The Meadows Original Frozen Custard, groceries and neighborhood services close at hand. Terraset Elementary, Langston Hughes Middle and South Lakes High School are all nearby, along with Reston National Golf Course, Reston Station and the WiehleReston East Metro. Private yet connected, architecturally distinctive yet comfortable, 11424 Purple Beech Drive captures what Reston was designed to be: a home, a landscape and community working together.
