[ THE CHALLENGE ]  Rebuild stairways in urban neighborhoods that can become dynamic elements in the streetscape, expressive of the human presence.

[ THE RESPONSE ]  In Cambridge. shop-fabricated steel and pre-cast concrete assemblies line the fronts of brick townhouses, arcing outward to define outdoor spaces associated with each apartment. In Chelsea, a four story stairway in a tight urban neighborhood is wrapped in spaced wood-fiber composite boards, creating a striking composition of solids and voids to screen private terraces.
