Welcome to 5810 Overlea Road, a beautifully maintained 5 bedroom, 2 full and 2 half bath residence in Bethesda's coveted Sumner neighborhood, where timeless mid-century modern architecture meets extraordinary privacy and thoughtfully curated natural surroundings. Lovingly cared for by the same owners for more than 33 years, this one-of-a-kind home reflects a deep appreciation for landscape, design, and seamless indoor-outdoor living. Surrounded by mature gardens inspired by the owners' extensive travels abroad, the home offers a peaceful retreat just minutes from downtown Bethesda and Washington, D.C. Inside, newly refinished hardwood floors, fresh interior paint, and abundant natural light create warm, inviting living spaces. The renovated kitchen (2016) features Silestone countertops, abundant cabinetry, a skylight, and opens to a welcoming sunroom (with an indoor cooking hearth) overlooking the backyard and pool. The spacious living room is framed by expansive Pella windows with direct access to the patio, and features a gas fireplace for cozy evenings. The main level also includes a handsome den with custom built-ins, a renovated powder room, a versatile fifth bedroom or home office with window bench seating, and a spacious primary suite with its own door to the patio and pool. The brand-new spa-inspired primary bath creates a luxurious private retreat. Upstairs are three generously sized bedrooms, a full bath, skylight, abundant closet space, and a large walk-in attic providing vast, convenient storage. The finished lower level offers a spacious recreation room with built-in bookshelves, a refreshed half bath, utility area with new flooring, and a flexible bonus room ideal for a gym, studio, or additional storage. A small garage provides storage while the driveway offers convenient off-street parking. Garage space can easily be reclaimed by removing the non-structural wall. Outdoor living is the true centerpiece of 5810 Overlea Road. The private backyard features a stunning Sylvan swimming pool, expansive flagstone patio, landscape lighting, hardscaping, and exceptional gardens cultivated over decades. Towering hemlocks, Japanese maples, dogwoods, redbuds, river birch, ginkgo, flowering plum, azaleas, and seasonal plantings create a serene, park-like setting rarely found in Bethesda. Ideally located in the highly desirable Sumner neighborhood and within a prized school district, the home is just a few blocks from the Capital Crescent Trail and a short walk to The Shops at Sumner. Enjoy easy access to downtown Bethesda, Friendship Heights, Chevy Chase, Washington, D.C., the Capital Beltway, parks, shopping, dining, and major commuter routes. Combining iconic mid-century modern design, exceptional privacy, beautifully established gardens, and an unparalleled indoor-outdoor lifestyle, 5810 Overlea Road presents a rare opportunity to own one of Bethesda's most distinctive and meticulously cared-for homes.
