Set along one of Spring Valley's most established streets, 3615 49th Street is a 1935 English Tudor extensively reimagined in 2012 by McLean-based Morris-Day Designers and Builders under architect Rob Morris. Spanning approximately 5,700 square feet, the residence is defined by architectural integrity, craftsmanship, and enduring character. Steep gables, half-timbering, textured masonry, and leaded windows preserve the essence of traditional Tudor architecture while introducing a more refined modern livability. A stone stair ascends through layered gardens to a facade framed by climbing greenery and architectural detailing that feels timeless and established. Set within nearly half an acre, the surrounding landscape gives the home a notable sense of privacy within the city. Inside, the foyer opens to a series of formal rooms shaped by rich millwork, stained glass, exposed beams, and balanced proportions. The living room and library share a double-sided wood-burning fireplace, creating two connected gathering spaces, while French doors from the library open directly to the rear gardens and stone patio. Throughout the main level, paneled walls, bespoke woodwork, and textured materials create warmth and architectural depth. A recurring rose motif within the custom interior glasswork lends a subtle signature to the home. The dining room is grounded by beamed ceilings and garden-facing windows, while at the rear of the residence, the family room rises beneath a cathedral ceiling with skylights and a gas fireplace, drawing inspiration from the great halls and ateliers that informed the renovation. Designed for both everyday living and larger gatherings, the kitchen sequence centers around a classic AGA range, substantial cabinetry, a generous island, and a sunlit breakfast area. An adjoining scullery and secondary kitchen provide additional preparation and service space. From the rear living spaces, the home transitions naturally to an expansive stone terrace overlooking the landscaped grounds. Occupying a private position on the second floor, the primary suite includes a spacious bedroom, walk-in closet, and marble bath with a soaking tub, dual vanity, walk-in shower, and beamed ceiling detailing. Two additional bedrooms share a Jack-and-Jill bath, with laundry conveniently positioned on the same level. The top floor introduces two additional bedrooms, a full bath, attic storage, and a walk-in cedar closet, creating flexibility for guests, office space, or creative use. The lower level takes on the atmosphere of an old-world tavern, complete with a wet bar, fireplace, built-ins, ribbed ceiling detailing, and integrated seating. An exercise room, full bath, storage areas, and an extended mudroom connect directly to the attached two-car garage. Moments from Spring Valley Park, neighborhood shops, restaurants, and top-rated schools, 3615 49th Street combines timeless design and day-to-day livability within one of Washington's most established residential enclaves.
