Admiralty House in London is a Grade I listed building facing Whitehall, currently used for UK government functions and as ministerial flats. It was opened in 1788 and until 1964 was the official residence of the First Lords of the Admiralty. Admiralty House is a four-storey building of yellow brick. The front facade has a symmetrical facade of three broad bays and one additional small bay at the southern end.
The rear facade is of five bays and faces Horse Guards Parade, with a basement-level exit under the corner of the Old Admiralty Building. The front of the house faces Whitehall; its main entrance is in the corner of the Ripley Courtyard, cutting through the corner of the older Ripley Building, to which it is connected on the first and second floors.
