Sky lobby

One World Trade Center (Manhattan)

One World Trade Center is the tallest skyscraper in New York City. Like the original World Trade Center buildings it replaced, the new building has a sky lobby to reduce the amount of space devoted to elevators. The sky lobby is on the 64th floor; each set of five to six stories is served by a separate bank of elevators. The elevators to the sky lobby, along with the ones used for the nonstop service to the 100th-floor One World Observatory, are the fastest in the Western Hemisphere. The observatory elevator transports passengers 100 floors in under one minute.

875 North Michigan Avenue (Chicago)

The John Hancock Center's sky lobby on the 44th floor serves only the residential portion of the building that occupies 48 floors (floors 45–92). Three express elevators run from the residential lobby on the ground floor to the 44th floor, with all three of the elevators stopping at one of the parking garage levels. At floor 44, residents transfer to two banks of three elevators. One bank serves 21 floors (floors 45–65) and the other serves 28 floors (floors 65–92). Although all six elevators stop at floor 65, this floor is roughly the same layout as the residential floors immediately above and below it. It is not a sky lobby because residents can also board elevators to higher floors at floor 44.

The tower's 44th floor sky lobby includes a pool, gym, dry cleaner, convenience store, about 700 mailboxes, two "party" rooms, a sitting area overlooking Lake Michigan, a small library, a refuse room (with trash chutes emptying here), offices for the managers of the residential condominium,{{cite web |access-date=2008-01-07}} and a polling station for residents during elections.

Floors above 92 are serviced by direct passenger elevators from the ground floor, and by two freight elevators that serve 55 floors (floors 44 to 98).
