I don't think a supertall will rise on this site. If they get to 700 ft on this site alone, that would be good. It's not a very large site. Between 200-250k sf could give it a height somewhere around 520 Park Avenue. That one is about 780 ft. Though that building is built with a FAR of 8.
The numbers for total built and zoning space for 520 Park...
