London, SW1A
Old War Office, Whitehall, which used to be a major MOD office. Over the years many notable names have been based there, including Winston Churchill, David Lloyd George, Lord Kitchener, and TE Lawrence, better known as Lawrence of Arabia. MOD staff moved out of the building and were mostly re-located across the road into Main Building, which is in effect the MOD’s Head Office. It is estimated that consolidating staff in one building will save at least £8 million per year in running costs.
