Hillingdon House is a Grade II listed mansion in Hillingdon, Greater London. The original house was built in 1717 as a hunting lodge for the Duke of Schomberg. It was destroyed by fire and the present house was built in its place in 1844.
The British Government purchased Hillingdon House in 1915 and it became a Military Hospital. In 1917, what would become the Royal Air Force station RAF Uxbridge was established within the grounds. In military use, the house has served over time as the first headquarters for No. 11 Group RAF and RAF Bomber Command. The River Pinn passes through the grounds of the house from north to south, splitting the former RAF Uxbridge in two.
During the final years of Military Ownership, Hillingdon House was occupied by the Service Prosecuting Authority, Civil Aviation Authority's Air Proximity Board & London Air Traffic Control. The house was Grade II listed on 5 June 1984. Under plans approved in early 2011 for the redevelopment of the RAF station, the house will be renovated and converted to include a Restaurant and Function Rooms.
