This two-story penthouse on top of a historic cast iron building in Tribeca was originally completed in 2006, but has never been occupied. It contains 3800 interior square feet on two levels, and 3400 square feet of exterior terrace.

We proposed three simple moves for making this cavernous undifferentiated space a home. First, by expanding the openings to the exterior we connected the interior space to the large exterior space, maximizing natural natural light exposure and creating a yard in the city. Second, we created an open communicating stair in the thin overlapping zone between the two levels. Third, we created a hierarchy of spaces, scaled to domestic life.
