Set within the iconic landmark, The OWO, this remarkable three-bedroom residence unites historic grandeur with world-class service. Once the seat of the Ministry of Defence—and steeped in the legacy of Churchill and Ian Fleming—this Grade II listed Edwardian Baroque masterpiece has been reimagined as London’s most prestigious new address, home to 85 exclusive residences fully managed and serviced by Raffles.*


Residence 1.15 spans 2,379 sq ft and has been designed with both entertaining and everyday living in mind. Generous ceiling heights create an impressive sense of space, while original period features—including sash windows and ornate cornicing - have been meticulously preserved. Interiors are calm and refined, with a palette of soft neutrals and layered textures. Each of the three double bedrooms benefits from its own en-suite bathroom, while the principal suite also boasts a private dressing area.


As part of The OWO, residents enjoy access to an unparalleled array of private amenities: a 25-metre indoor pool, vitality pools, cinema, lounges, treatment rooms, and a world-class gym. The adjoining Raffles London - the brand’s first UK hotel - offers nine restaurants, three bars, and the hallmark of its reputation: bespoke, discreet service. From concierge and valet to butlers, spa therapists, private chefs, and in-residence dining, the lifestyle offering is among the most comprehensive in London.


Ideally positioned between Whitehall and St James’s Park, and just moments from Westminster, Mayfair, and the West End, this residence presents a rare opportunity to own a home in Britain’s historic and political heart, with every modern comfort seamlessly provided.
