[1] Built in 1882 by Walter Maximilian de Zoete, the manor house is known for its distinctive Flemish style architecture, its connection to influential individuals, and its notable use during World War I as an auxiliary hospital.

[3] When put up for sale in 1909, the brochure prepared by John D. Wood & Co. estate agents boasted interior feature walls panelled in teak, a national telephone line, a burglar alarm system for the ground floor and an electric plant building producing 100 ampere 150 volt current for lighting the mansion and other buildings on the estate.

[7] At the onset of World War I in 1914, Sir Robert generously offered Warren House to the British Red Cross Society for use as a 50-bed hospital.

In 1934, Gordon Ralph Hall-Caine, MP of Woolley Firs, Maidenhead, briefly owned The Warren but he never took up residence, before it was purchased by the Receiver through the offices of Lady Margetson, wife of Major Sir Philip Margetson, the Deputy commissioner of the Metropolitan Police, for use by the Metropolitan Police as a sports club.

Following extensive conversion work, The Warren officially opened as the Club House and sports grounds on 13 June 1935, inaugurated by Marshal of the Royal Air Force, Lord Trenchard, Commissioner of Police of the Metropolis.

[11] During World War II, the stables were used as headquarters for the local Home Guard, and the Club became a favorite rendezvous for pilots such as 'Sailor' Malan, Stanford Tuck, Jamie Rankin, Al Deere, Don Kingaby and E. H. Thomas, from nearby Biggin Hill Airport.

Today, The Warren serves as a sports and social club for members and retirees of the Metropolitan Police Service, as well as for the local community.
