A rare opportunity to own a piece of British history, reimagined for contemporary living.

The OWO is home to 85 extraordinary private residences, each offering the hallmark service and discretion of Raffles, within one of London's most iconic landmarks. Formerly the Old War Office - once the workplace of Winston Churchill and said to have inspired Ian Fleming - this Grade II*-listed Edwardian Baroque masterpiece has been thoughtfully restored and transformed by the Hinduja Group and Onex Holding.

Perfectly positioned on Whitehall, just moments from Downing Street and St James's Park, The OWO places residents at the epicentre of British power and prestige. Inside, original architectural grandeur meets refined modern design. Soaring ceilings, elegant proportions and bespoke finishes define homes crafted for comfort, privacy, and understated sophistication.

Every detail has been considered - from the formal arrival experience to the seamless flow of interior spaces and dedicated resident-only amenities. Paired with Raffles' legendary hospitality, The OWO delivers a living experience unlike any other in London – where heritage and innovation live side by side.

As part of The OWO destination, residents also enjoy access to 30,000 sq ft of private amenity space, alongside a world-class Guerlain spa, nine destination restaurants and three bars.
