One of the penthouse's stunning details (rest assured, there are many more) is its glass and marble floating staircase which connects the residence's two floors. New York City views go uninterrupted via glass window walls.

The open air stairwell has a modern art museum feel with the stairs constructed from glass and marble and white walls setting off striking sculptures and paintings.

The penthouse has 7,400 square feet of living space and 14-feet ceilings which show off the New York City skyline from every room.

Floors throughout the apartment are made from 6-inch wide ebony stained white oak. They're a grounding pairing with walls of glass that offer up incredible panoramas of New York City's most iconic vistas.
