Your opportunity to own a piece of British history has arrived. In the heart of Whitehall, where whispers of wartime strategy once echoed through marble-clad corridors, an extraordinary metamorphosis has taken place.
The Old War Office—a Grade II* listed masterpiece that witnessed nearly a century of world-shaping decisions—has emerged from an ambitious transformation as The OWO, London’s most anticipated architectural renaissance.
With the Hinduja Group and Onex Holding at the helm, this Edwardian baroque landmark – which once housed the offices of Churchill, was John Profumo’s base when he was Secretary of State, and inspired Ian Fleming to write the James Bond series after working for Britain’s Naval Intelligence Service – now stands as a testament to the delicate art of preserving heritage while defining modern luxury.
“No expense has been spared in bringing [The OWO] back to its former glory and paying homage to its heritage, whilst breathing new life into it.”
This 760,000-square-foot Whitehall icon marries London’s first Raffles hotel with 85 of the capital’s most sophisticated private residences, creating an unprecedented fusion of historical gravitas and contemporary refinement.
Behind its Portland stone façade, The OWO now houses nine restaurants—including culinary experiences from Michelin-starred virtuosos Mauro Colagreco and Endo Kazutoshi—alongside a Guerlain spa that brings Parisian wellness expertise to the heart of London. Yet it’s the building’s soul, shaped by over a century of history, that truly sets it apart. From its origins as the site of the original Palace of Whitehall to its role as a nerve centre of British military operations, these walls have witnessed the making of history.
