An exceptional 4 bedroom duplex penthouse at The OWO, offering 3,804 sq ft of Banda designed interiors, 1,765 sq ft of terraces, 3.15m ceilings, London views and Raffles services.

Description

The Westminster Residence is an exceptional 4 bedroom duplex penthouse occupying the 6th and 7th floors of The OWO Residences by Raffles, a beautifully reimagined Grade II* listed landmark in the heart of Whitehall. Offering approximately 3,804 sq ft of internal accommodation, 1,765 sq ft of terraces and impressive 3.15m ceiling heights, this remarkable London residence combines grand proportions, privacy and expansive outdoor living.

The interiors by Banda Design Studio unite vintage pieces, bespoke furniture and richly crafted materials, creating a home of extraordinary depth and individuality. The upper level is devoted to living and entertaining, with an impressive reception and dining room, bespoke bar, formal dining space, kitchen and multiple terraces. French windows connect the principal reception room directly to the main terrace, while the kitchen and dining room open onto a more intimate terrace with views towards the London Eye.

The private lower level comprises the principal bedroom suite with dressing room and bathroom, alongside 2 further bedroom suites, with the 4th bedroom and bathroom positioned on the upper floor. This considered arrangement creates a distinct separation between the home’s spectacular entertaining spaces and its quieter private accommodation.

Residents benefit from an exceptional collection of private amenities and Raffles services, including a dedicated residential concierge, 24 hour security, residents’ lounges, landscaped garden, cinema, fitness and treatment facilities, and access to the hotel swimming and vitality pools.

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.

Square Footage: 3,804 sq ft
Leasehold with approximately 241 years remaining.
