Carlton House Terrace

Carlton House Terrace is a street in the St James's district of the City of Westminster in London. Its principal architectural feature is a pair of terraces of white stucco-faced houses on the south side of the street overlooking St. James's Park. These terraces were built on Crown land between 1827 and 1832 to overall designs by John Nash, but with detailed input by other architects including Decimus Burton, who exclusively designed No. 3 and No.4. This building was once the original location for offices belonging to the Information Research Department , a secret branch of the UK Foreign Office dedicated to creating pro-colonial and anti-communist propaganda during the Cold War.
The land on which Carlton House Terrace was built had once been part of the grounds of St James's Palace, known as "the Royal Garden" and "the Wilderness". The latter was at one time in the possession of Prince Rupert of the Rhine , and was later called Upper Spring Garden.
