London, a city that understands the alchemy of transforming history into relevance, has once again unveiled a treasure. This autumn, a building that once echoed with the weight of global decisions has been reborn, not merely as a hotel, but as a testament to enduring significance. Raffles London at The OWO, a name that now signifies a new pinnacle of elite experiential travel, occupies the monumental Edwardian Baroque edifice that once served as Britain’s Old War Office. It is here, within these hallowed walls, that Winston Churchill and his wartime cabinet navigated the storm of the Second World War, shaping not only a nation’s destiny but the very course of the 20th century. This is London at its most ambitious, a city that truly masters the art of monumental hospitality.
Few establishments globally can claim such an intrinsic connection to pivotal historical moments. Even fewer possess the vision and meticulous care to translate that gravitas into an experience of contemporary luxury without dilution. The OWO’s transformation is a narrative of profound respect for heritage, guided by an architectural hand—Thierry Despont, renowned for his masterful reinvention of iconic landmarks like the Statue of Liberty. The result is an immersive journey that transcends mere accommodation; it is an invitation to inhabit history itself.
The six-year restoration was not simply a renovation; it was a meticulous archaeological and artistic undertaking. Every detail, from the original dark wood carvings that adorn the stately rooms to the translucent alabaster balusters and the 37 historically preserved fireplaces, speaks of a bygone era imbued with enduring craftsmanship. These elements are not mere decorative afterthoughts; they are integral to the very soul of the building, seamlessly woven into the fabric of its luxurious modern life. The iconic double staircase, a silent witness to countless historic figures and decisions, still commands attention, its grandeur preserved and amplified. It serves as a constant reminder that this is a place where history was made, and now, where new, exclusive experiences are crafted.
Located in Whitehall, the very epicentre of British governance, The OWO’s significance is amplified by its context. It stands adjacent to the Royal Horse Guards, a stone’s throw from Buckingham Palace, and a short stroll from the Houses of Parliament, Westminster Abbey, and the serene expanse of St. James’s Park. This is not a prime location chosen for mere convenience, but for its deep historical and cultural resonance. The Thames flows nearby, a constant artery of the city’s lifeblood, while the vibrant West End theatres and the dynamic energy of Covent Garden and Soho are just a heartbeat away. To stay at Raffles London at The OWO is to be immersed in the intellectual and political heart of London, offering a perspective rarely accessible. This proximity to iconic landmarks and cultural hubs ensures guests are at the nexus of London’s most captivating experiences.

The concept of wellness at The OWO is approached with the same gravitas and considered depth as its architecture. Beneath the historic structure lies the Guerlain Spa, a subterranean sanctuary designed not for fleeting indulgence, but for profound restoration. With nine treatment rooms offering both traditional and innovative therapies for body and mind, it provides a tranquil escape from the city’s pulse. Complementing this is a magnificent 20-metre indoor pool and vitality pool, described poetically as a ‘cathedral of calm,’ complete with hydrothermal facilities to enhance the sense of escape and rejuvenation. Pillar Wellbeing further elevates the experience by offering a contemporary, performance-led approach to optimal wellbeing, encompassing active training, bespoke wellness programming, and memberships. The state-of-the-art gym and movement studios, supported by one-to-one coaching and a health-conscious juice bar, reflect a holistic philosophy that nurtures movement, nutrition, recovery, and mental fitness—a vital component for the discerning traveller.
Moments of gathering and celebration find their perfect stage within spaces that once hosted state affairs. The Whitehall Ballroom, entered via the breathtaking Grand Staircase, is transformed from a former corridor of power into an unparalleled setting for exclusive events and private celebrations. It offers a unique blend of historical grandeur and contemporary elegance, capable of hosting gatherings that are both dazzling and discreet. The six flexible meeting rooms, also benefiting from the building’s majestic architectural features, cater to high-level executive meetings and private symposiums, where discretion and a distinguished environment are paramount.
True to the Raffles legacy, the service at The OWO transcends mere hospitality. It is defined by intelligence, intuition, and an unwavering commitment to discretion. The Raffles Butlers are not simply attendants; they are trusted insiders, curating unique journeys and exceptional experiences that extend far beyond the hotel’s walls. Their deep understanding of London, cultivated through impeccable training and contemporary insight, ensures that every guest’s stay is imbued with authenticity and effortless grace. They are loyal companions, dedicated to making every visit distinct and memorable, today and for all future endeavours.

The Haldane Suite at Raffles London by OWO was used by the Secretary of State during World War II.
The 120 guest rooms and suites within Raffles London at The OWO are a sophisticated reimagining of classic Edwardian style, infused with Thierry Despont’s signature flair. Each space reflects the building’s storied past while offering modern comforts and discerning design. From custom-designed furniture and lighting to bespoke amenities, including a unique signature scent developed by renowned London perfumer Azzi Glasser—a captivating blend of Sicilian bergamot, neroli, wild sage, rich vetiver, cedarwood, and sequoia, grounded by oakmoss and black oudh—every element is considered. The guest room corridors themselves tell a story, with carpet designs inspired by original floor grilles and historical building textures, and window treatments subtly alluding to the iconic Horse Guards uniforms. It is a masterclass in creating environments that are both historically resonant and supremely comfortable, ensuring a stay that is as richly layered as the building’s own history.
Raffles London at The OWO is more than just a new luxury hotel; it is a rare opportunity to inhabit a significant piece of history, reimagined with profound restraint, unwavering respect, and contemporary relevance. It is a destination for those who understand that the most compelling experiences are often found where the past meets the present in a dialogue of enduring quality and exceptional access. The stories held within these walls—from wartime strategy sessions to Ian Fleming’s inspiration for James Bond—now become part of the guest’s own narrative. This landmark address, once a seat of power, is now London’s most intriguing new destination for discerning travelers.
For those who value context as much as comfort, and access as much as elegance, this remarkable journey is available through private consultation.
