10 Downing Street or “Number 10” as the British call it, is one of the most famous addresses in the world as it has been the home of British prime ministers since 1730. However, it is also a very busy place where hundreds of people work and where many official functions, Cabinet meetings and state dinners take place. Many people will immediately recognise the front of the building because the Prime Minister and other well-known politicians often make important announcements in front of its famous big black door.Number 10 was originally given to the first prime minister, Sir Robert Walpole, as a gilt, but he wanted it to be used by all future prime ministers. Before he moved in, though, he joined 10 Downing Street to the large house behind it and had some alterations made. So even though Number 10 looks like an ordinary terraced house from the outside, inside it is an extremely grand place. There are many beautiful rooms with elegant decor and fine furniture including the State Dining Room, the Study, the Terracotta Room and the White Drawing Room. There are portraits of every past prime minister hanging on the walls of the Grand Staircase and in the Cabinet Room, where government ministers meet to discuss important issues. The table in this room is boat-shaped so that the Prime Minister can always see everyone sitting around it!The Prime Minister’s private home is a furnished flat on the second floor, once described by Margaret Thatcher (British Prime Minister from 1979-1990) as “living above the shop”. The Prime Minister also has his own study where he works and reads. There, he often meets colleagues, receives important guests, makes phone calls or gives interviews.
