Set above the street and directly across from Rock Creek Park, this distinguished 1929 residence offers exceptional privacy, gracious proportions, and wonderfully versatile living spaces in a serene, tree-canopied setting. One of three neighboring homes originally built for three sisters, the property combines historic character with a warm, comfortable layout designed for both everyday living and memorable entertaining. At the heart of the home is an inviting open kitchen and family room with a fireplace accented by antique Dutch tiles and French doors opening to an expansive deck and spectacular rear grounds. Terraced gardens, mature trees, generous lawn, and a swimming pool create a private outdoor retreat with abundant space for dining, entertaining, recreation, and gardening. The main level offers an elegant formal dining room, gracious living room with fireplace, and multiple flexible gathering spaces. A particularly special sunroom features three walls of glass and a heated slate floor, providing a cozy year-round vantage point for enjoying the surrounding landscape. A separate library/media room lined with bookshelves offers yet another comfortable retreat. Upstairs, well-proportioned private spaces are complemented by an expansive attic offering exceptional flexibility for an office, studio, storage, or other uses. The lower level adds remarkable versatility with an au pair/guest suite and full bath, a spacious recreation room, extensive storage, and a former two-car garage currently configured as an impressive art and woodworking studio with direct access to the driveway and the potential to be converted back to garage use. With Rock Creek Park just across the street and a welcoming neighborhood immediately beyond the rear garden, this is a rare opportunity to enjoy privacy, space, and nature while remaining beautifully connected to city life.
