In the event of war, the war room would have housed the Regional Commissioner and his staff who would have directed the strategic response to air raids throughout the counties of Berkshire, Buckinghamshire, Dorset, Hampshire, Oxfordshire, and the Isle of Wight. The Regional Commissioner had the authority to assume the full powers of the central government in this region if contact with central government was lost.

The development of the hydrogen bomb and the expectation of mutually assured destruction meant that the war room was both inadequately protected, and seen as too small to support the large live-in staff that would be needed after a major nuclear strike. Its principal responsibilities were transferred to a new Regional Seat of Government RSG-6 at Warren Row near Maidenhead. Some sources suggest that it continued in use as a civil defence communications centre for some period after this transfer.
