Carlos Aparicio Skyscraper Staircase

Ebony panels on the walls and a Roman statue humanizes a lofty space in the heart of Manhattan in this design by Carlos Aparicio. "Architecture, engineering and antiquities are all working together here for an awe-inspiring staircase," says Brian Gluckstein."It's especially impressive since it's in an apartment on the 70th floor."
