Six dormitories were built in the Secret Bunker which were intended to sleep up to 300 personnel. As the bunker had to be on full alert 24 hours a day, 7 days a week a 'hot beds' principle had to be adopted.
With employees working up to 18 hours a day, they could then rest for 6 and then swap their bunk with another member of personnel when they started their next shift.
The Secretary of State had his own suite of rooms and the private secretary and military liaison staff were also all provided with separate living quarters. The Minister of State had his own private office which overlooks the nuclear operations room.
