This 18-unit luxury apartment is located at the edge of Lyon Park, a well-established and desirable single family neighborhood in Arlington, Virginia and a short walk to Clarendon, a high-density, transit-oriented, mixed-use community. A site organization and massing strategy was devised to acknowledge the transitional nature of the site and respond appropriately to the varied context. The façade facing the single-family neighborhood breaks down into house-like forms conducive to the porous residential street. The residential vocabulary is reinforced by large terraces that evoke the porch structures of nearby neighbors and overlook a lushly planted front yard. Vehicular access is provided off an adjacent alley create an uninterrupted new streetscape and parking is tucked under the building, minimizing impervious area. The material palette is a mix of the familiar (brick and wood) and the modern (metal and glass) assembled in a contemporary manner.
