How long has buckingham palace been built for?

Buckingham Palace has been the official London residence of the UK's sovereigns since 1837. The site has been used for a royal palace since the 17th century, but it was originally known as Buckingham House. It was acquired by King George III in 1761 and underwent significant renovations over the next few decades, including the addition of the east wing and the central block. In the early 19th century, King George IV commissioned architect John Nash to transform the palace into a grand royal residence. Nash's plans were extensive and included the construction of the Marble Arch, the State Dining Room, the Grand Staircase, and the Waterloo Gallery. The work on the palace was completed in 1837, and it has been used as the official London residence of the British monarchy ever since.
