Downing Street

Downing Street is a street in Westminster in London that houses the official residences and offices of the Prime Minister of the United Kingdom and the Chancellor of the Exchequer. Situated off Whitehall, it is long, and a few minutes' walk from the Houses of Parliament. Downing Street was built in the 1680s by Sir George Downing. For more than three hundred years, it has held the official residences of both the First Lord of the Treasury, the office now synonymous with that of the Prime Minister, and the Second Lord of the Treasury, the office held by the Chancellor of the Exchequer. The Prime Minister's official residence is 10 Downing Street, and the Chancellor's official residence is Number 11. The government's Chief Whip has an official residence at Number 12. In practice, these office-holders may live in different flats; the current Chief Whip actually lives at Number 9. The houses on the south side of the street were demolished in the 19th century to make way for government offices now occupied by the Foreign, Commonwealth and Development Office. The term "Downing Street" is also used as a metonym for the Prime Minister or the British Government more generally. The street was built in the 1680s by Sir George Downing, 1st Baronet, on the site of a mansion, Hampden House. It is not known what was on the site before the mansion, but there is evidence of a brewhouse called 'The Axe', owned by the Abbey of Abingdon. Downing was a soldier and diplomat who served under Oliver Cromwell and King Charles II, and who invested in properties and acquired considerable wealth. In 1654, he purchased the lease on land east of St James's Park, adjacent to the House at the Back, and within walking distance of Parliament. Downing planned to build a row of townhouses "for persons of good quality to inhabit". However, the Hampden family had a lease which prevented their construction for 30 years. When the Hampden lease expired, Downing received permission to build further west to take advantage of recent developments.
