This 1902 Victorian-style home in the D.C. suburbs had gorgeous original architectural features—vaulted ceilings, large windows. The challenge? Creating a seamless transition between the original structure and an addition. Plastered walls, wood beams, casual fabrics, and a limestone fireplace contribute to the living room’s relaxed Montecito vibe and help make the transition into the dining room, the first room in the new section of the home, feel less stark. Influences from the couple’s travels to the Middle East, such as accessories and floor coverings, are featured throughout and create cohesion. The kitchen is quietly colorful and incredibly functional, with tiled walls that create easy clean-up for the family. The bedrooms all maintain an airy, calming quality, including the kids’ rooms, which are whimsical enough to be child-appropriate but sophisticated enough to grow into.
