"175 Park": NYC former Trump Grand Hyatt effects on NYCT Grand Central STATION and TERMINAL

I emphasize STATION because it's not the Terminal lol, but will also help the GCT

Its use of stone and visual symmetry will pay homage, SOM explained, to the Beaux-Arts style of Grand Central Terminal, which it will connect to via a new transit hall and an improved street-level passage and subway entrance via 42nd Street.

The project also sits directly over the 4/5/6 subway lines of the Grand Central-42nd Street subway station. The existing building's girders obstruct the subway mezzanine, so SOM plans to use the demolishment and rebuild process to carefully remove the girders and improve the layout for the underground train station too.

In collaboration with the MTA, SOM will build new and accessible entrances and expand circulation to ease congestion.

A new looping shortcut will also be created to link up the subway mezzanine, the lower-level Metro-North Railroad platforms and the almost completed East Side Access Terminal.

500 room hotel... but 83 stories for the building itself.

I had to muck with some figures... using average hotel room sizes, I could get 128 rooms per floor. Now this will be a bit less for various reasons, so 125 is a good figure that calculates nicely. That means just for the rooms, 4 floors. Of course, they'll make suites and massive family rooms and such, and since this is New York, we can safely double that to 8 floors.

Add a conference level, a dining/receiving level, internal business and laundry... 11 floors?

That'll get it down to 72 floors. Take 4 out for a indoor mall and foot traffic from Grand Central, the subway stop, and outside.

68 floors.

Damn that's a lot of office space... and no word on residences.

From Wikipedia:

The structure would contain office space on the 7th through 63rd floors and a 500-room Grand Hyatt hotel on the 65th through 83rd floors

Ahhh, the renderings are what I was missing. Okay, 18 floors as the building is tapered.

Still, that's a lot of office space.
