Like so many of our NYC projects, this one began with a family’s need to expand their 1,000-sq. ft. living quarters by purchasing an adjacent apartment.   We first consulted with this family when they were considering the purchase of the identical apartment directly above.  The structural complexity of the existing art-deco skyscraper yielded few rational locations for the new stair, but relocating the apartment entry to a former bedroom allowed the kitchen to relocate while all the bedrooms could move to the new upper level.
