Where does the British prime minister live and work?

The British prime minister lives and works at 10 Downing Street in London. This historic building serves as both the official residence and the office for the head of the United Kingdom government.1

The site has been associated with the office of the prime minister since the 18th century. While it has been used as a residence sporadically since 1735, it has served as the continuous home for prime ministers since 1902. The complex includes private living quarters, offices, state rooms for hosting dignitaries, and a dedicated room for Cabinet meetings. In recent years, some prime ministers have opted to reside in the more spacious living quarters located at the adjoining 11 Downing Street. Due to its significance, the term "Downing Street" is often used metonymically to refer to the British prime minister or the government itself.12
