57 Whitehall, better known as the Old War Office in London that was once occupied by the country's war-time Prime Minister Winston Churchill has been sold to private developers. They plan to restore and re-develop the 580,000 sq-ft building into a five star hotel and residential apartments with private function rooms as well as a spa and fitness facility.

The Old War Office is a heritage-listed property. It has around 1,100 rooms across seven floors which are linked by more than two miles of corridors. It was constructed in the years between the start of the 20th century and the outbreak of the First World War and has played an important role in the history of the last century. Previously it was inaccessible to the public but a commitment has been made to grant new access to the building with an outdoor public space as part of the re-development plans.
