Offered for the first time in nearly three decades, this distinguished Colonial residence occupies one of Spring Valley's most coveted addresses, quietly positioned on a sought-after cul-de-sac and steps from Spring Valley Park. Built in 1932 and thoughtfully maintained , the elegant home has been beautifully curated, including interiors by renowned Washington designer Mary Douglas Drysdale. Behind its timeless faade, gracious proportions, exceptional scale, and a rare sense of permanence define every level of the residence. A welcoming foyer introduces a series of remarkable entertaining spaces. To one side, the grand formal dining room is ideally suited for both intimate dinners and large-scale gatherings. Opposite, a cloak room provides convenience for guests. Beyond, the expansive formal living room stretches across the rear of the home, with French doors opening to the terrace, pool, and beautifully landscaped grounds. Equally impressive is the library and music room, anchored by a fireplace and offering a warm and inviting retreat for everyday living. The heart of the home is the extraordinary kitchen, exceptionally well-appointed with extensive custom cabinetry and adjoining office space. The kitchen opens to a substantial breakfast room featuring a fireplace and a custom banquette, creating a true gathering space designed for conversation, connection, and daily life. The second level is anchored by a spacious primary suite with French doors overlooking the rear gardens and pool, separate dressing areas, and a spa-inspired bath. Two additional ensuite bedrooms on this floor offer generous proportions and abundant natural light. The top level provides three additional bedrooms, a hall bath, and extensive hidden storage thoughtfully integrated throughout the floor. The lower level offers exceptional flexibility with a recreation room, powder room, laundry area, storage, and a private guest or au pair suite. Direct access to the garage further enhances everyday convenience. Outside, mature landscaping creates a private oasis centered around the swimming pool, terrace, and pool cabana, providing exceptional spaces for both entertaining and relaxation. Rarely does a residence of this scale and location become available in Spring Valley. Cherished by the same family for nearly three decades, this is an extraordinary opportunity to become the next steward of a home that has been lovingly maintained and enjoyed for generations.
