Wimbourne House (also known as Wimborne House or the William Kent House) is a historic townhouse at 22 Arlington Street in St James's, a district of the City of Westminster, England. Designed in the Neo-Palladian style by William Kent, it was built between 1743 and 1754, being completed after the architect's death. It is a Grade II* listed building, and the west front overlooks Green Park. The building now houses special event rooms for the adjacent Ritz Hotel.
The Prime Minister Henry Pelham hired Kent to design the house at the time of his elevation to the office. Kent died in 1748, and Pelham himself died shortly after the completion of the house in 1754. The house then became a temporary residence for Granville Leveson-Gower, 2nd Earl Gower, followed by the Prime Minister Augustus FitzRoy, 3rd Duke of Grafton. In the 1770s, the house was reclaimed by Henry Pelham-Clinton, Earl of Lincoln, a relative of its original owner. He started a renovation of the house, but he died before its completion. In 1840, the house was acquired by the war veteran Henry Somerset, 7th Duke of Beaufort. He financed an extensive renovation of the house by the architect Owen Jones. In 1852, the house was sold to William Hamilton, 11th Duke of Hamilton. Following his death, the house was eventually acquired by Ivor Guest, 1st Baron Wimborne who added a new ballroom to the house. Most of the additions made to the house during the 18th and 19th centuries were removed in the 1970s, in an effort to restore the house to the original design of William Kent.
