Admiralty House in London was opened in 1788 and until 1964 was the official residence of the First Lords of the Admiralty.

Admiralty House was designed by Samuel Pepys Cockerell, a protégé of Sir Robert Taylor, and opened in 1788. Built at the request of Admiral of the Fleet Viscount Howe, First Lord of the Admiralty, in 1782–83 for "a few small rooms of my own",[citation needed] it was the official residence of First Lords of the Admiralty until 1964, and has also been home to several British Prime Ministers when 10 Downing Street was being renovated. U.S. President John F. Kennedy attended a meeting there with Prime Minister Harold Macmillan in 1962 to discuss the allies' reaction to the communist threat and more wide-ranging matters.[citation needed]

Winston Churchill lived in the house while serving as First Lord of the Admiralty for two terms, 1911–15 and 1939-40. It now contains government function rooms and three ministerial flats.

Admiralty House is part of a complex of former Admiralty buildings and is sometimes confused with the more visible Ripley Building (also known as the Old Admiralty Office), built in 1726, or the Admiralty Extension, built between 1898 and 1904, and also with Admiralty Arch (1910).
