The Centre for National Security building was constructed with private funds unknowingly provided by the criminal organization SPECTRE and was designed to be the headquarters of Britain's combined intelligence agencies, along with the surveillance equipment necessary for the "Nine Eyes" programme. The building's construction was supervised by the Director-General of the Joint Security Service, Max Denbigh (C), whose office was situated at the top floor. During the film's climax, M, Q, Moneypenny and Bill Tanner break into the building to prevent "Nine Eyes" and arrest Denbigh. During an altercation between Denbigh and M several windows are shot and the falling debris causes Denbigh to fall to his death from the top floor.
