At the northern end of the site were the headquarters of the Stationery Office, which had originally been the "Parliamentary Mews" built in 1825 by Decimus Burton and converted from 1853 to 1855.

[1] In 1958, it was decided that there would be an open space on the southern edge of the site by Broad Sanctuary, and an architectural competition for a conference hall and government offices was held in 1961.

The competition was won by William Whitfield, but the scheme was not executed due to the plans for redeveloping Whitehall drawn up by Leslie Martin in 1965.

The centre is a very successful venue hosting over 400 meetings each year and returning an annual dividend to the Exchequer, thus not reliant on the taxpayer for financial support.
