About this property

Each of the 85 residences is utterly unique — shaped by the building’s historic layout — with elegant proportions, bespoke finishes and a formal arrival experience befitting this singular address.

The West End’s cultural offer — the National Gallery, National Portrait Gallery, Royal Opera House, Covent Garden — is within easy reach, as are the private members’ clubs of St James’s. Westminster, Embankment and Charing Cross stations provide immediate connections across London and beyond.

Investment
The OWO occupies a position in the London market that is genuinely without precedent: a Grade II*-listed landmark on Whitehall, managed by Raffles, with only 85 residences and a historical narrative that no other address in the world can replicate. Heritage buildings of this calibre — where restoration cost, listed status and location combine at this level — are never built again. For private banking clients seeking a London asset that appreciates on the strength of its own identity as much as market dynamics, The OWO is in a category of its own.
