In this townhouse we take advantage of an unusual opportunity to connect the lower three floor levels directly to a new rear yard terrace. The multi-story connections brings light and air but also a sense of openness, connectivity and space usually not possible in a townhouse. The new rear terrace is accessed from three levels: the Parlor level from a new glass vestibule, the ground level through glass doors and the lower level from the stairway. The new interior stair, multi storied fenestration and interior shelving (and a climbing rope) connect the levels vertically.
