Exceptional 2-bed, 2-bath, 14,242 sq ft 4th-floor residence at The OWO, offering grand proportions, refined design and access to world-class Raffles service and amenities.

Description

This extraordinary 2-bedroom, 2-bathroom residence on the 4th floor of The OWO spans an unprecedented 14,242 sq ft, offering one of the largest and most impressive interior footprints within the building. Defined by monumental scale, exquisite detailing and beautifully balanced volumes, this home represents a rare fusion of historic grandeur and contemporary refinement.

Once the Old War Office—where statesmen, strategists and visionaries shaped the modern world—this iconic Edwardian Baroque landmark has been meticulously transformed into a globally significant destination anchored by London’s first Raffles Hotel. Behind its Portland stone façades, residents enjoy a lifestyle supported by legendary five-star service, unparalleled privacy, curated dining, atmospheric bars and an exceptional wellness spa.

The residence itself combines the character of masterfully restored architecture with serene, modern interiors designed for comfort, elegance and effortless living. Its vast proportions invite grand entertaining as well as moments of quiet luxury, all within one of the most prestigious addresses on Whitehall.

A rare opportunity to inhabit an extraordinary home within one of London’s most historic and magnificently reimagined buildings.

Location

The OWO occupies a privileged position on Whitehall, at the eastern edge of St James’s. Strolling its broad pavements is to experience days of old; a throwback to London’s regency grandeur.

It is home to some of the city’s most established specialist shops, well-versed in serving royalty, alongside venerable institutions: from Christie’s and the Royal Academy, to innumerable members’ clubs.

Today, the old guard is joined by a new generation of restaurants, boutiques, galleries and clubs, from White Cube to the cutting-edge Dover Street Market.

This is one of the world’s few great places that remain untouched by generic luxury. It is all the more precious for it.
