Conversion of a 3-family, wood-frame townhouse to 2-family occupancy. An owner’s duplex was created in the lower portion of the building by combining two existing floorthrough apartments. The center of the project is a double-height stair hall featuring a bridge connecting the two upper-level bedrooms. Natural light is pulled deep into the center of the building down to the 1st floor through the use of an existing vestigial light shaft, which bypasses the 3rd floor rental unit.
