A domed roof crowns the elevator lobby atop the terraced structure.

Green marble panels cover elevator lobby walls, and granite tiles in pale and dark tones cover the floor.

This pattern extends from the granite-paved plaza into the ground-floor lobbies of the two towers, where the floors and elevator lobby walls are also granite.
