The building also incorporates a number
of additional facilities. The mezzanine level, with a view out
to 53rd Street, will house a small coffee bar and will look back
over the main hallway with a dramatic view of a two-story atrium.
The building extends two levels underground: one floor will hold
the new auditorium and classroom facilities, while the lowest
level will house museum offices and a library and archive. At
the entrance level will be a new Museum store, with access during
non-Museum hours via a separate exit to the street.
