Other floors at Lumon Industries are known to exist, thanks to information revealed on the displays visible in the Security Office. They indicate the existence of a bank of at least four elevators ostensibly capable of reaching 16 total floors.

From top to bottom, the visibly named floors are:

• 13: Unnamed
• 12: Machine
• 11: Exec. Ste
• 10: Sr. Ste
• 9: Conf. Rm
• 8: Conf. Rm
• 7: IT
• 6: Acq.
• 5: Data P.
• 4: Net. Sys.

None of these floors are seen or described in season one. Burt, however, at one point mentions “the executive wing upstairs,” which may be a reference to the eleventh floor.

Six further floors appear to exist below the fourth, but their names are not legible.

The real-life building used for exterior shots of Lumon Industries, the Bell Labs Holmdel Complex, has only six floors.^[1]
