St James's Square

St James Square is the only square in the exclusive St James's district of the City of Westminster. It has predominantly Georgian and neo-Georgian architecture and a private garden in the centre. For its first two hundred or so years it was one of the three or four most fashionable residential address in London, and it is now home to the headquarters Transnational corporations, including BP and Rio Tinto Group, as well as some exclusive clubs and the London Library.

Addresses

The numbering starts with Number 1 to the north of Charles Street on the eastern side of the square and proceeds anti-clockwise as far as Number 21. The Army and Navy Club's clubhouse occupies the former sites of Number 22, a smaller adjacent house which may have had a George Street number, and several former houses in Pall Mall. Norfolk House at the southern end of the square is Number 31, and the two houses to its north are Numbers 32 and 33. A small house in the angle of the square south of Norfolk House, originally numbered in John Street, and the adjacent house in Pall Mall, have been combined and allocated the number 31A.

The smaller houses along the southern side had Pall Mall numbers until 1884. This block is now occupied by a mixture of 19th and 20th century buildings which are fully built up to the pavements on both sides. Some of them have their main entrance in Pall Mall and others in the square, and there are two separate sets of numbers for them. The numbers in the square range from 22A to 30, with some omissions.
