Ideally located in one of Bethesda’s most coveted neighborhoods—Fort Sumner—this stately colonial embodies timeless charm, thoughtful functionality, and meticulous care. Lovingly maintained by its owners for 27 years, the home was built in 1958 by O.F. Smith Brothers, renowned for innovative design and superior construction. Positioned on a high point in the neighborhood, the property benefits from excellent drainage and a beautifully level lot on a quiet street. This gracious residence offers five bedrooms and features a fabulous two-story rear addition that transformed the primary suite into a true retreat while adding a spacious, sun-filled family room. The addition also expanded one of the upper-level bedrooms and added a fourth bathroom. The flexible floor plan offers a main-level bedroom or dedicated first-floor office, and the two-car garage provides direct access to the kitchen—an increasingly rare and valuable feature. A welcoming foyer with coat closet and powder room opens to a bright, expansive formal living room featuring a wood-burning fireplace with a beautiful hearth and mantel. The formal dining room flows seamlessly into the kitchen, while stunning glass pocket doors connect to the sun-drenched family room—surrounded by windows, enhanced by recessed lighting, and anchored by a second wood-burning fireplace. This inviting space opens directly to a flagstone patio and backyard, ideal for indoor-outdoor living. The kitchen, ready for your personal touch, offers ample space for a table or potential island and includes many updated appliances. Just off the kitchen, the two-car garage provides exceptional storage with an additional refrigerator, extensive overhead and wall storage, and an attached shed for even more space. The upper level features four generously sized bedrooms, three full bathrooms, and a large linen closet. The expanded primary suite is truly exceptional, offering abundant closet space, a sitting area with soaring ceilings, and a gas fireplace flanked by custom built-ins. The luxurious en-suite bath overlooks the backyard and includes a soaking tub, heated floors, heated towel rack, oversized shower, double vanity, and private commode. An additional flexible space is perfect for a desk, exercise area, or quiet retreat. A walk-up attic, fully insulated and floored, provides outstanding storage and houses the second HVAC system. A solar panel system significantly reduces energy costs. The finished lower level, perfect for a recreation or playroom, features wood beams, a custom bookcase, a third wood-burning fireplace, and walk-out access to the backyard. This level also includes a fourth full bathroom, laundry area, and utility/storage room. The level backyard is a private haven for fun and relaxation, complete with a hot tub—ideal for unwinding at the end of the day. The professionally landscaped yard is alive with beautiful plantings.
