Whitehall Court in London, England is one contiguous building but consists of two separate constructions; the end occupied by the National Liberal Club was designed by Alfred Waterhouse, the major part (including the Royal Horseguards Hotel) was designed by Archer & Green.
The Royal Horseguards Hotel, owned by Thistle Hotels[1], covers 1 & 2 Whitehall Court. The remainder (3 & 4 Whitehall Court) is still residential.
Whitehall Court was built during the mid-1880s by Archer & Green with financing provided by Jabez Balfour. The story that led to the creation of the building is described in Jabez: The rise and fall of a Victorian rogue by David McKie.
Well-known residents have included George Bernard Shaw, H. G. Wells, Sarah Caudwell and Stafford Cripps. James Compton Merryweather, the fire engineer, lived at number 4 from before 1902 to his death in 1917. It is also home to the Farmers Club, the United Nations Association UK and Liberal International, which is housed within the National Liberal Club.
The building forms part of the vista, frequently photographed by tourists, from the bridge in St. James's Park looking towards Horse Guards Parade.
It was used as Secret Intelligence Service (MI6) headquarters until the end of World War I.
