Downing Street is a street in London, United Kingdom, known for housing the official residences and offices of the Prime Minister and the Chancellor of the Exchequer. "Downing Street" is used as a metonym for the Government of the United Kingdom.
Downing Street is off Whitehall in central London, a few minutes' walk from the Houses of Parliament and a little further from Buckingham Palace. The street was built in the 1680s by Sir George Downing. 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 and Commonwealth Office.
For more than three hundred years it has held the official residences of the First Lord of the Treasury, an office now synonymous with that of Prime Minister, and the Second Lord of the Treasury, an office held by the Chancellor of the Exchequer. The Prime Minister's official residence is 10 Downing Street; the Chancellor's official residence is next door at Number 11. The government's Chief Whip has an official residence at Number 12, although the current Chief Whip's residence is at Number 9.
The street was built in the 1680s by Sir George Downing, 1st Baronet, on the site of a mansion, Hampden House. What was on the site before the mansion is vague, but there is evidence towards 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 Saint 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. The new warrant issued in 1682 reads: "Sir George Downing ... [is authorised] to build new and more houses further westward on the grounds granted him by the patent of 1663/4 Feb. 23. The present grant is by reason that the said Cockpit or the greater part thereof is since demolished; but it is to be subject to the proviso that it be not built any nearer than 14 feet of the wall of the said Park at the West end thereof." 
Between 1682 and 1684, Downing built the cul-de-sac of two-storey townhouses with coach-houses, stables and views of St James's Park. How many he built is not clear; most historians say 15, others say 20. The addresses changed several times; Number 10 was numbered 5 for a while, and was renumbered in 1787. Downing employed Sir Christopher Wren to design the houses. Although large, they were put up quickly and cheaply on soft soil with shallow foundations. The fronts had facades with lines painted on the surface imitating brick mortar. Winston Churchill wrote that Number 10 was "shaky and lightly built by the profiteering contractor whose name they bear".
The upper end of the Downing Street cul-de-sac closed access to St James's Park, making the street quiet and private. An advertisement in 1720 described it as "a pretty open Place, especially at the upper end, where are four or five very large and well-built Houses, fit for Persons of Honour and Quality; each House having a pleasant Prospect into St James's Park, with a Tarras Walk". The houses had several distinguished residents. The Countess of Yarmouth lived at Number 10 between 1688 and 1689, Lord Lansdowne from 1692 to 1696 and the Earl of Grantham from 1699 to 1703. The diarist James Boswell took rooms in Downing Street during his stay in London during 1762–63 at a rent of £22 per annum. He records having dealings with prostitutes in the adjacent park.
Downing probably never lived in his townhouses. In 1675 he retired to Cambridge, where he died a few months after the houses were completed. His portrait hangs in the entrance foyer of the modern Number 10.
The Downing family also built Downing College, Cambridge, which was established in 1800, after its founder Sir George Downing, 3rd Baronet, left a portion of his estate to establish Downing College when the land became available. (A door from Number 10 is in use in the college).
The houses between Number 10 and Whitehall were acquired by the government and demolished in 1824 to allow the construction of the Privy Council Office, Board of Trade and Treasury offices. In 1861 the houses on the south side of Downing Street were replaced by purpose-built government offices for the Foreign Office, India Office, Colonial Office, and the Home Office.
Houses in Downing Street
10 Downing Street is the official residence of the First Lord of the Treasury, the Prime Minister of the United Kingdom, as with almost no exceptions, the two roles have been filled by the same person since the 1720s. It has fulfilled this role since 1735.
12 Downing Street, formerly the Chief Whip's Office, houses the Prime Minister's Press Office, Strategic Communications Unit and Information and Research Unit. In the 1820s it was occupied by the Judge Advocate-General, although it remained in private ownership. It entered government hands when purchased by the East India Company in 1863, and was occupied by the marine and railway departments of the Board of Trade. It was originally numbered 13, but was partially re-built and re-numbered following the demolition of Number 14 in 1876. It was badly damaged by fire in 1879, and underwent further changes.
14 Downing Street formerly closed off the western end of the street. It was acquired by the Crown in 1798, and was used by the War Office and Colonial Office in the 19th century. Some parts were demolished in the 1860s, and by 1876 it had been removed completely.
15–16 Downing Street, long since demolished, formerly housed the Foreign Office, which also occupied two houses on the south side of the street.
18 Downing Street was occupied by the West India Department of the Colonial Office.
20 Downing Street was occupied by the Tithe Commission.
The houses at the end of the street were arranged around Downing Square.
There used to be a public house, the Rose and Crown, in Downing Street. In 1830 the tenant was a Mr Dixon.
Throughout the history of these houses, ministers have lived by agreement in whatever rooms they thought necessary. On some occasions Number 11 has been occupied not by the Chancellor of the Exchequer but by the individual considered to be the nominal deputy Prime Minister (whether or not they actually took the title); this was particularly common in coalition governments. Sometimes a minister only uses the Downing Street flat for formal occasions and lives elsewhere.
During his last period in office, in 1881, William Ewart Gladstone claimed residence in numbers 10, 11 and 12 for himself and his family. He was both Chancellor of the Exchequer and Prime Minister at the time.
After the 1997 general election, in which Labour took power, a swap was carried out by the incumbents of the two titles, Tony Blair being a married man with three children living at home, while his counterpart, Gordon Brown, was unmarried at the time of taking up his post. Although Number 10 was the Prime Minister's official residence and contained the prime ministerial offices, Blair and his family actually moved into the more spacious Number 11, while Brown lived in the more meagre apartments of Number 10. This was the second time this had occurred; Stafford Northcote lived in Number 10 at one point, while Benjamin Disraeli occupied Number 11. That was for precisely the opposite reason—at the time, Number 10 was the more spacious apartment and Sir Stafford had a larger family. Blair and Brown's arrangement continued between Brown (at 11) and Alistair Darling (at 10), and continued in the Cameron ministry (David Cameron at 11 and George Osborne at 10) Theresa May and Philip Hammond have also continued this arrangement. .
Downing Street gates
Barriers were erected at the St James's Park end of the street for the unveiling of the Cenotaph on 11 November 1920. They were a public safety measure intended to prevent the crowds in Whitehall becoming too dense.
When the movement for Irish independence became increasingly violent, it was decided to retain the barriers, which were raised and strengthened. On 26 November 1920 construction commenced on a wooden barricade, 8 feet (2.4 m) high at the end of the street. They were described as being of a "substantial character" mounted on proper foundations and incorporated vehicle gates. The barriers were taken down in 1922 when the Irish Free State was created.
Vehicle access was curtailed in 1973 when metal barriers were placed across the entrance to the street. In 1974, the Metropolitan Police proposed erecting a semi-permanent barrier between the pavement and carriageway on the Foreign Office side to keep pedestrians off the main part of the street. The proposal came with assurances that tourists would still be permitted to take photographs at the door of Number 10. The Prime Minister, Harold Wilson, rejected the proposal, feeling that it would appear to be an unacceptable restriction of the freedom of the public. Wilson's private secretary wrote "I much regret this further erosion of the Englishman's right to wander at will in Downing Street."
In 1982 access was further restricted by railings and a demountable gate. They were replaced by black steel gates in 1989. The increase in security was due to an increase in violence, particularly by the IRA during The Troubles. The Thatcher ministry was particularly moved to increase security after the 1979 assassination of Lord Mountbatten.
Public right of way
The public right of way along Downing Street has not been extinguished nor subject to a gating order and the road retains the status of a public highway maintained by Westminster City Council. Public access was curtailed by relying on common law powers to prevent breach of the peace (although its legality has been questioned by a correspondent for New Statesman magazine). In 2005 Westminster City Council used anti-terrorism powers contained in the Civil Contingencies Act 2004 to formalise the restrictions by means of a traffic management order.
Although the Downing Street government buildings and grounds are a designated site under the Serious Organised Crime and Police Act 2005 for criminal trespass, the street was not included in the boundaries of the designated area.
Since 1989, entering Downing Street has required passing through a security checkpoint. The street is patrolled by armed police from the Diplomatic Protection Group, and there is usually at least one police officer outside the front door of Number 10. Security was tightened after 10 Downing Street was mortar bombed by the IRA in 1991.
