Review of Raffles London at The OWO

The Raffles London at The OWO made its spectacular debut in September 2023 and has quickly become a benchmark for luxury hospitality in the heart of the UK capital. Within its first year, this illustrious property has joined the ranks of the world’s elite city hotels, standing shoulder-to-shoulder with the legendary Raffles Singapore, a flagship that has defined opulence for generations.

The storied Old War Office (OWO), constructed in the early 1900s, served as a strategic nerve centre for the British government until 2016. Its enviable location mere steps from 10 Downing Street and its grand Edwardian Baroque architecture have ensured its place among London’s most revered heritage sites.

The property’s transformation is the vision of the Hinduja family, one of the world’s most influential business dynasties. Today, The OWO is a multifaceted destination, boasting nine restaurants, three sophisticated bars, 85 Raffles-branded residences, and the crown jewel: Raffles London at The OWO.

This exclusive hotel offers just 120 lavish guest rooms and suites, a Guerlain Spa, the holistic Pillar Wellbeing health club with a 20-metre subterranean heated pool, The Drawing Room, Pillar Kitchen, the clandestine Spy Bar, and the refined Guards Bar and Lounge. The entire culinary program is orchestrated by Mauro Colagreco, whose Mirazur in France has been awarded three Michelin stars and ranked among the world’s best. His distinctive touch elevates each of his London venues: Mauro Colagreco at Raffles London, Mauro’s Table, and Saison by Mauro Colagreco.

The extensive restoration of The OWO spanned seven years and required an investment that has been widely discussed in hospitality circles. The result is a masterclass in adaptive reuse, blending historical gravitas with contemporary luxury. The exceptional staff—meticulously trained and genuinely welcoming—cement Raffles London at The OWO’s status as one of London’s top three hotels for discerning travellers.

Cinephiles will recognize the Old War Office from its appearances in five James Bond films, where it played the backdrop for both MI6 and the enigmatic ‘M’. Its cinematic legacy includes roles in Octopussy, A View to a Kill, Licence to Kill, Spectre, and Skyfall, where its domed towers are unmistakable.

Once shrouded in secrecy and frequented by intelligence officers, military leaders, and historic figures such as Ian Fleming, the OWO is now open to the public, offering guests the rare opportunity to immerse themselves in a living monument at the heart of London’s political and cultural epicentre.

Raffles Hotels & Resorts, under the ACCOR umbrella, continues to expand its global presence with 24 properties in its portfolio, including this London flagship. Destinations range from Paris and Istanbul to the tranquil surrounds of Siem Reap, Cambodia, each reflecting Raffles’ commitment to exceptional heritage and guest experience.

Whitehall, the historic artery of central London, seamlessly links Parliament Square with Trafalgar Square, placing guests at the epicentre of the city’s political and cultural landscape.

Raffles London at The OWO occupies a commanding position, bordered by Whitehall, Whitehall Court, Whitehall Place, and Horse Guards Avenue. The hotel’s main entrance faces the esteemed Royal Horse Guards, renowned for the annual Trooping the Colour ceremony.

This area is synonymous with British governance, with major ministries and the Prime Minister’s residence at 10 Downing Street just a brisk two-minute stroll away.

Guests are within effortless reach of London’s most coveted attractions: Trafalgar Square and Nelson’s Column, Westminster Abbey and the Houses of Parliament, the Cenotaph, Covent Garden’s Royal Opera House, the West End’s acclaimed theatres, Leicester Square’s cinemas, and the vibrant district of Soho.

For seamless connectivity, Westminster and Charing Cross underground stations are a short walk, providing rapid access across London and beyond.

International arrivals are well served: Eurostar’s St Pancras International is a 20-minute drive or direct tube ride, while both Paddington (for Heathrow Express) and Victoria Station (for Gatwick Express) are approximately 15 minutes by car. London Heathrow is typically a 60-minute drive, and Gatwick is around 90 minutes by road, traffic permitting. For European travellers, London City Airport offers swift access, just 30 minutes away by car.

Raffles London at The OWO showcases a remarkable selection of 19 distinct room and suite categories, offering just 120 exclusive accommodations. This boutique scale ensures an intimate, bespoke experience, with pricing reflecting the hotel’s uncompromising commitment to quality and craftsmanship.

The entry point is a 31-square-metre Classic Room, featuring a sumptuous king bed and walk-in rainfall shower. From there, options include Superior and Deluxe Rooms (including twin configurations), spacious Executive Rooms for up to three guests, and a diverse array of suites: Junior, Westminster, Lifestyle, Ministerial, Corner, Turret, and the signature Raffles, Churchill, Granville, and the palatial Haldane Suite spanning an impressive 181 square metres (1,948 sq ft).

Regardless of category, every guest is enveloped in the same standard of refined design, comfort, and attention to detail. The late Thierry Despont—renowned for his work on The Carlyle, Claridge’s, and The Dorchester—crafted interiors that seamlessly blend heritage with contemporary luxury, making this hotel a lasting testament to his genius.

Arrival amenities are thoughtfully personalised—during my stay, a Churchill quote accompanied by a whimsical chocolate cigar was a delightful touch.

Bathrooms are a standout, fitted with underfloor heating, state-of-the-art Japanese toilets, premium fixtures, expansive mirrors, rainfall showers, plush towels and robes, slippers, and a full suite of eco-conscious amenities. The exclusive 1906 OWO toiletries, created in partnership with Azzi Glasser and a member of the Hinduja family, evoke the building’s Indian heritage with subtle sandalwood notes.

The beds—whether king or double—are supremely comfortable, dressed in crisp linens and downy duvets, with a generous pillow selection. Technology is seamlessly integrated: large smart TVs, ample USB ports, and ultra-fast Wi-Fi are standard. Grand drapery and privacy sheers frame each window.

Suites offer additional living space, with deep carpets, plush sofas, substantial desks, and curated artwork. Many rooms retain original features such as wood panelling, fireplaces, ornate ceilings, and cornices, connecting guests to the building’s storied past.

Families and pet owners are warmly welcomed, with thoughtful amenities for both children and dogs.

Room outlooks vary: those facing the inner courtyard promise tranquillity, while Whitehall-facing rooms offer a captivating view of the city’s vibrant daily life—ideal for people-watching from your private sanctuary.

While Raffles London at The OWO may lack a helipad or private golf course, it delivers virtually every other amenity expected of an ultra-luxury hotel.

The breadth and quality of facilities are exceptional, with a particular focus on wellness. The concierge team is available around the clock, ready to fulfill any request, from private city tours to last-minute theatre bookings.

The Guerlain Spa, a global leader in luxury wellness since 1828, offers a sanctuary spanning four floors and 27,000 square feet. With nine treatment rooms—including three VIP suites for individuals and couples—guests can indulge in advanced therapies delivered by expert aestheticians, rejuvenating both body and mind.

The spa complex also includes a state-of-the-art gym, movement studio, 20-metre heated indoor pool beneath soaring ceilings, a beauty atelier for bespoke fragrance, makeup, and hairstyling, a thermal spa suite, and the Pillar Kitchen for nutritious cuisine as part of the holistic Pillar Wellbeing program.

For those seeking exclusivity, the Royal Spa Suite offers private, tailored wellness rituals.

Since opening, the hotel has introduced a curated portfolio of guest experiences, with the historical tours and Afternoon Tea proving especially popular. These immersive journeys explore the OWO’s fascinating narrative—from its wartime role to its cinematic moments and remarkable transformation into a modern landmark.

Positioned within walking distance of Westminster Abbey, Parliament Square, Trafalgar Square’s renowned galleries, Soho’s entertainment, Mayfair’s boutiques, and St. James’s classic barbers and cigar lounges, the hotel is an unrivalled launchpad for exploring the capital’s best.

Tracing the OWO’s journey reveals a tapestry of British history and architectural ambition.

In 1532, Whitehall’s origins began with Cardinal Wolsey’s palatial residence, built from brilliant white Ashlar stone and giving the area its name. Fast-forward to 1898, when the government commissioned a new War Office, resulting in a formidable trapezium structure with six-foot-thick walls and foundations plunging 30 feet below ground. Over 26,000 tons of Portland stone, 3,000 tons of York stone, and 25 million bricks were used, culminating in a Renaissance-inspired—now Edwardian Baroque—masterpiece. The building features 1,000+ rooms and more than four kilometres of corridors, crowned by domed towers and a majestic Grand Staircase.

Officially opened in 1906, the Old War Office became the operational hub for defence strategy through both World Wars, hosting figures like Haldane, Kitchener, and Churchill. Despite multiple bombings, the building sustained only minor damage. It was here that MI5, MI6, and the SAS were conceived, and T.E. Lawrence (Lawrence of Arabia) served before his legendary exploits abroad.

After housing the Ministry of Defence from 1964, the OWO was vacated in 2016. The Hinduja family secured a 250-year lease and invested over USD 1.7 billion in transforming this Grade II* listed site into a contemporary icon, meticulously balancing historic preservation with modern luxury over a seven-year restoration.

Three new basement levels were constructed to accommodate the spa, ballroom, parking, and storage, while upper floors were rebuilt or added for new venues. The challenge was immense: every one of the 76,000 square metres across 14 floors was reimagined, with over 35 consultants—including English Heritage—ensuring the building’s soul remained intact.

Homages to the past abound: suites are named after legendary British spies and statesmen, and original architectural details are lovingly preserved throughout. The experience is immersive—wood panelling, marble staircases, hidden rooms, original artwork, intricate ceilings, mosaic floors, and soaring columns create an atmosphere that is both stately and welcoming. The press photography captures the scale and splendour, but nothing compares to experiencing the hotel in person.

The OWO’s culinary scene is a true gastronomic destination, featuring nine restaurants and three distinctive bars.

Paper Moon delivers contemporary Italian fare for lunch and dinner, while Café Lapérouse offers Parisian favourites throughout the day. Michelin-starred chef Endo Kazutoshi brings refined Japanese cuisine to Kioku by Endo. Pillar Kitchen focuses on health-driven menus, and Langosteria introduces Milanese dining with flair. The hotel’s own venues include The Drawing Room for all-day classics—think lobster club sandwiches—and three signature experiences by Mauro Colagreco: Saison, Mauro’s Table, and the flagship Mauro Colagreco at Raffles London.

The Guards Bar & Lounge serves as the main social hub, while the Spy Bar channels the building’s clandestine past in a subterranean speakeasy setting. Kioku Bar is renowned for its curated sake offerings, served at your preferred temperature.

In-room dining is available around the clock—my late-night French fries arrived piping hot and perfectly seasoned.

Mauro Colagreco, one of the world’s most celebrated chefs, oversees all hotel dining. His accolades include three Michelin stars in France and collaborations with Air France La Première. While his London restaurant has not yet been awarded a Michelin star, its reputation among gourmands continues to rise, and expectations remain high for future recognition.

Colagreco’s culinary ethos is rooted in sustainability and seasonality, with over 70 varieties of British produce featured across his menus. Saison offers Mediterranean-inspired breakfasts and a lavish Champagne Sunday lunch, while Mauro’s Table is an intimate private dining experience for up to 20 guests, featuring a constantly evolving five-course menu.

The signature Mauro Colagreco at Raffles London is open Tuesday to Saturday for lunch and dinner, presenting à la carte, tasting, and lunch menus. Themed menus—such as the recent tomato celebration—highlight his playful creativity and commitment to local ingredients.

The dining room is understated, with elegant furnishings and natural light, allowing the food and service to shine. The wine list impresses with its breadth, offering everything from organic vintages to inventive non-alcoholic pairings.

Service is exemplary: attentive yet unobtrusive, knowledgeable, and genuinely passionate. During my visit, General Manager Melissa Fergus ensured each guest’s experience was flawless, demonstrating the kind of discreet excellence found at top Michelin-starred establishments.

My tasting menu journey included smoked fish in red oak lettuce, Salt Marsh lamb with aubergine mole, Cornish turbot in raspberry sauce, and a striking dulse seaweed ice cream with white chocolate and yuzu. Each course was a sensory revelation, beautifully presented and bursting with flavour. Special requests and dietary preferences are handled with ease and creativity.

A visit to the Spy Bar for a post-dinner Macallan capped an unforgettable culinary adventure. Colagreco’s arrival in London has invigorated the city’s dining scene—this is a must for any serious food lover.

ACCOR and Raffles are deeply committed to advancing sustainability throughout their operations. The group’s initiatives emphasise ethical sourcing, championing local artisans and producers, and stewardship of both natural and cultural heritage. Conservation is embedded in the hotel’s DNA—from energy-efficient building systems to responsible water use and waste minimisation. By the close of 2025, Raffles aims for at least 75% of its energy to be derived from renewable sources, in line with global hospitality sustainability benchmarks.

Culinary operations prioritise local sourcing, food waste reduction, and a strong focus on plant-based dining options. The guest experience is further enriched by opportunities to engage with community projects, cultural preservation efforts, and environmental restoration. The restoration of The OWO itself was a monumental act of heritage conservation, involving hundreds of artisans and experts to breathe new life into this architectural icon while minimising its environmental footprint at every stage.

• Heritage Revitalisation – The conversion of the OWO into a world-class hotel, spa, residences, and dining destination has redefined adaptive reuse in luxury hospitality. Despite the enormous investment, the project is a resounding success. As a frequent reviewer of luxury properties, I can attest that few new openings capture a sense of place as authentically as Raffles London at The OWO. The only shortfall? The Argentinian sharing bread is an acquired taste! The property feels timeless, even in its infancy—OWO truly dazzles.
• Team Excellence – From the iconic bowler-hatted doormen to the attentive housekeeping and spa teams, professionalism and warmth are woven into every guest interaction. Managing Director Philippe Leboeuf brings a wealth of experience from leading legendary hotels like Hôtel de Crillon and Claridge’s, setting the tone for exemplary service at every level.
• Attention to Detail – Every element, from the curated art and heritage features to the modern amenities, reflects a deep respect for the building’s history and an intuitive understanding of the modern luxury traveller’s needs. The Concierge hall, with its striking desk, historic clock, Saad Quereshi sculpture, and bespoke furnishings, is a personal favourite—a microcosm of the hotel’s unique character.Varun SharmaEditor in ChiefBusinessclass

• The OWO Legacy – During my London days, strolls through St James’s Park often led me to this enigmatic building. Its stately presence piqued my curiosity long before I ever imagined working here. The opportunity to be part of its transformation was irresistible.
• Historical Significance – The OWO’s storied past resonates deeply, especially as someone with family ties to wartime Europe. Its heritage is palpable at every turn, making it a privilege to contribute to its next chapter.
• Wellness Focus – My passion as a hotelier has always been rooted in wellness. While operations encompass all areas of hospitality, I believe the future of ultra-luxury hotels lies in transformative wellness journeys, not just exceptional rooms.Philippe LeboeufManaging DirectorRaffles London at The OWO
