York House is a historic wing of St James's Palace, London, built for Frederick, Prince of Wales, on his marriage in 1736. It is in the north-western part of the palace on the site of a former suttling-house (canteen) for the Guards; it overlooks Ambassadors' Court and Cleveland Row to the west of the old Chapel Royal. Prince Frederick occupied it for about a year, until his quarrel with the his father drove him from Court. In 1795, Princess Caroline resided here before her marriage with the Prince of Wales, afterwards George IV. Prince Ernest Augustus, Duke of Cumberland, subsequently King of Hanover, lived here for a great many years; and the Duchess of Cambridge was identified with it from 1851 until her death in 1889. Later occupants included the future George V, the late Duke and Duchess of Gloucester from 1936 to 1970, and Princes Charles, William and Harry, who used it before moving to Clarence House.As Edward, Prince of Wales, the future Edward VIII lived at York House, before his refurbishment of Fort Belvedere in Windsor Great Park.The building includes a suite of somewhat low-pitched rooms on the ground-floor, several drawing-rooms on the first floor, a corridor in the rear, and the servants' rooms on the top storey; all facing Cleveland Row. The ceilings of the top floor are low, height having been sacrificed to that of the drawing-room floor; during the nineteenth century this was a common practice in London mansions. The name York House has been used at various times for other houses occupied by various Dukes of York, including those now known as Cumberland House, Dover House, Lancaster House and The Albany.

St James's Palace is the most senior royal palace in London, the capital of the United Kingdom. The palace gives its name to the Court of St James's, which is the monarch's royal court, and is located in the City of Westminster in London. Although no longer the principal residence of the monarch, it is the ceremonial meeting place of the Accession Council, the office of the Marshal of the Diplomatic Corps, and the London residence of several members of the royal family. Built by order of Henry VIII in the 1530s on the site of an isolated leper hospital dedicated to Saint James the Less, the palace was secondary in importance to the Palace of Whitehall for most Tudor and Stuart monarchs. Initially surrounded by a deer park and gardens, it was generally used as a hunting lodge and retreat from the formal court and occasionally a royal guest house. After the destruction by fire of Whitehall, the palace increased in importance during the reigns of the early Hanoverian monarchs but was displaced by Buckingham Palace in the late 18th and the early 19th centuries. After decades of being used increasingly for only formal occasions, the move was formalised by Queen Victoria in 1837. The palace now houses a number of official offices, societies and collections, and all ambassadors and high commissioners to the United Kingdom are still accredited to the Court of St James's. The palace's Chapel Royal is still used for functions of the British royal family. The palace was mainly built between 1531 and 1536 in red-brick, and its architecture is primarily Tudor in style. The Queen's Chapel was added in 1620s, and Clarence House was built directly next to it in the 1820s. A fire in 1809 destroyed parts of the palace, including the monarch's private apartments, which were never replaced. Some 17th-century interiors survive, but most were remodelled in the 19th century.

Arthur's was a London gentlemen's club, now dissolved, which was established in 1811 and was disbanded in 1940. Between 1827 and 1940 it was based at 69 St James's Street. It is now best remembered for having built the London clubhouse currently occupied by the Carlton Club. The club was first formed at a meeting at a bank at 16 St James's Street on 8 May 1811, with the resolution 'That a New Club be forthwith established, to consist of 300 Members.' The club is notable for being the first to be a members' club wholly owned by the members, as opposed to the proprietary clubs which previously existed, like White's, Boodle's, and Brooks's, and it accordingly served as the mould for most of the nineteenth century members'-owned clubs which followed.
