In a quiet residential pocket of Washington, this 3,300-square-foot home is a study in restraint, reimagined with a three-story addition that elevates the humble split-level into a layered, luminous expression of contemporary life. The architecture honors the original structure while asserting a new spatial rhythm that privileges context, clarity, and the quiet power of thoughtful detail. 

Inside, the plan unfolds with purposeful generosity. An open living and dining area, anchored by a monolithic black marble fireplace, flows into a kitchen equipped with walk-in pantry and custom millwork. A guest suite and mudroom sit quietly to the side, while the upper levels introduce a primary suite and loft space designed for both retreat and engagement. Two staircases, a sculptural white balustrade and a transparent glass spine, reinforce the home’s dual emphasis on movement and light.
