Since the early 1700's, nearly all British prime ministers have lived at what London street address?

The iconic black door at the heart of London’s Westminster district has long been synonymous with British political leadership. Since the early 18th century, this historic address has served as both the official residence and workplace for the nation's chief minister, making it one of the most recognizable buildings in the world. It stands as a powerful symbol of the UK government.

The tradition began in 1735, when King George II offered the house to Robert Walpole, who is widely considered Britain's first de facto prime minister. Walpole initially refused the gift for himself, insisting instead that it be given to the "First Lord of the Treasury" – a title that the prime minister still holds today. This established the precedent that the house would belong to the office (Review), not the individual, ensuring its continuity as the seat of power through successive administrations.

What appears to be a single grand townhouse is actually three separate properties combined into one, making it larger and more complex than its famous facade suggests. Beyond its distinctive exterior, the interior houses not only the Prime Minister's private apartment but also numerous offices, meeting rooms, and the Cabinet Room, where crucial government decisions are made. Its enduring role for over three centuries solidifies its place in British history and global politics.
