An unprecedented opportunity to own a piece of British history, reimagined for modern living. Once the Old War Office - where Winston Churchill once walked the halls and Ian Fleming found inspiration for the James Bond novels  - this Grade II*-listed Edwardian Baroque landmark has been meticulously restored and transformed by the Hinduja Group and Onex Holding.

At the heart of this transformation stands Raffles, synonymous with elegance, discretion, and world-class hospitality for over 130 years.
