This fine Grade II* Edwardian building has been transformed into a spectacular stage for dazzling celebrations; with fine dining, lively bars, the latest in wellness and beauty therapies, the most luxurious suites and rooms, versatile grand ballroom and event space.

Originally opened in 1906 to house Britain's War Office, this iconic Whitehall building was once inhabited by famous statesmen and spies from Lord Haldane to Winston Churchill and was among the inspirations behind Ian Fleming's James Bond. In fact many of the Bond movies had scenes filmed here.

A six year restoration has seen thousands of expert craftsmen and women transform The Old War Office, today known as The OWO, into London's most exciting premier destination for the city's most important occasions. Handsome State Rooms and grand offices have been transformed into 120 spacious guest rooms and suites with views of Whitehall and Horse Guards.

All this complemented by a 20-metre swimming pool, vitality pool, saunas and steam rooms, state of the art gym and movement studio.


The New War Office, designed by British architect, William Young, was opened on Whitehall to house 2,500 government and military officials. It was built in Edwardian Baroque style and it had over 1,000 rooms and 2.5 miles of corridor. King Edward VII (the eldest son of Queen Victoria) was monarch when it opened. 

The New War Office was the centre of the British Army's administration and it is from this building that Sir Winston Churchill helped mastermind the Allied Victory over Hitler.


The New War Office was used by Winston Churchill as Secretary of State for War from 1919 to 1921.


With the formation of the unified Ministry of Defence on 1 April 1964, much of the former Army Department transferred across Horse Guards into the MOD 'Main' Building. Reorganisation took place and the now 'Old' War Office retained an Army presence but also hosted RAF branches and the Navy's Hydrographer.


The Old War Office was sold as part of the disposal of British Government assets.


The new owners of The Old War Office, the Hinduja Group, receive the keys and start a meticulous six-year restoration of this historic building working with thousands of expert craftsmen and women. The building is now known as The OWO.


In Summer 2023, this former Old War Office in Whitehall, will open as The OWO.
