Seventy five feet of unobstructed views overlooking all of Central Park unfold at this rare white-box opportunity, ideally situated in the heart of the most desired block on Fifth Avenue.
This storied home was acquired in 1963 by the 41st Vice President Nelson Aldrich Rockefeller. Mr. Rockefeller broke through the building’s South wall and connected to 810 Fifth Avenue; installing a flight of six shallow steps to his home on the 12th floor. After his death in 1979, the apartments were re-divided and the 15th floor is now being offered for the first time since the original sale.
