The bunker consists of three levels: a bottom level used as a base for machinery and for some underground generators, also a fake floor to combat flooding; a middle level, detailed below; and an upper level used for storage and trunking.

We did not find any obvious sleeping quarters; during normal shift rotation the sleeping quarters would have been in Bempton village, although what would happen during an attack is unknown.
The Blast Doors
There are two separate blast doors set at right angles to the corridors so as to minimise
any blast impact (though the impact on the bungalow-side door would likely have been
negligible). This image is the bungalow-side door - the other side is identical.

C6: Main Operations Room
Actually, a more accurate title would be "First Operations Room", since we do not
know if this was the main room. It is, however, the biggest single area and features a whole
host of different functions. Because of the state of the floor in this room (ie.
nonexistent) and a 20ft drop to the lowest level in many sections, we were unable to explore
it any further than looking through the four doors along its length. This however is an
approximate map based on what we saw:
C7: Second Operations Room
The second operations room looks much more like it was an office or quarters, with
desk-height ventilation and a large overhead gantry leading to the storage space.
C14: Air Purification Plant
This is the main air turbine, which backs onto a primary air storage tank. The side of the
air tank had been removed, and the ceramic purifiers were visible inside. It is interesting
to note that we could not find any purifiers inside the complex itself and all air ducting
inside led to the tank leading off this turbine: there was no protection between the turbine
and the external vent (C17).
