The headquarters of the British Secret Intelligence Service, also known as Military Intelligence, Section 6, is located at 85, Albert Embankment in the south western part of central London, on the bank of the River Thames beside Vauxhall Bridge. Designed by Terry Farrell and built by John Laing, the Developer Regalian Properties PLC approached the government in 1987 to assess their interest in the proposed building. At the same time, MI6’s sister service MI5 was seeking alternative accommodation and collocation of the two organisations was considered.
