How many houses in Downing Street?

Answer 1

9 Downing Street was named in 2001 and is the Downing Street entrance to the Privy Council Office and currently houses the Chief Whip's office. It was formerly part of Number 10.

10 Downing Street is the official residence of the First Lord of the Treasury, and thus the residence of the British Prime Minister, as in modern times, the two roles have been filled by the same person. It has fulfilled this role since 1735.

11 Downing Street has been the official residence of the Second Lord of the Treasury since 1828, and thus the residence of the Chancellor of the Exchequer.

12 Downing Street, formerly the Chief Whip's Office, currently 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 became occupied by the marine and railway departments of the Board of Trade. It was originally Number 13, but was partially re-built and re-numbered following the demolition of Number 14 in 1876. It was badly damaged by a fire in 1879, and underwent further changes as a result.

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 andColonial 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 held the Foreign Office, which also occupied two houses on the west 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.
