We connected a ground floor flat with the apartment above to create a duplex maisonette in a 1929 Art Deco building on the East Side of Manhattan. Our new cantilevered cast-iron stair is the centerpiece of the apartment. Dark floors and stark white plaster walls reinforce its boldness.
We created new public spaces and linked them vertically by the stair and horizontally with wide openings and subtle level changes. The living room and dining room open to an ivy-walled garden.
