Behind the door of Number 10: discover the secrets and the long history of Theresa May's new home in Downing Street

David Cameron has moved out and Theresa May is about to move into the most famous address in the country, but what do we really know about it?

Although the house has been the official residence of the prime minister for nearly three centuries, no PM has lived there since 1997 when Tony Blair decided No 11 had more space for his growing family.

The houses are linked via a corridor and connecting doors, so Chancellor George Osborne could live at No 10 and hold Treasury meetings at No 11 and vice versa for Mr Cameron.

In fact, No 10 consists of four houses: the one we know from our TV screens, a very large house behind it which was joined up with No 10 in the early 18th century, No 11 to its left and parts of No 12 to the left of No 11, making up a property with more than 100 rooms.

Although No 10 is the new prime minister's official residence, Mrs May won't be given the door keys because there is always someone to let in the PM. Besides, there isn't a door handle on the outside.

It's thought that Theresa May, a keen cook, will move into the larger house at No 11 which was fitted with a stunning £25,000 Roundhouse kitchen and bespoke accessories when the Camerons moved in six years ago.
