Building works on the palace dragged on through the final years of George's reign. By the time he died in 1830, costs had more than quadrupled. As soon as the King was dead, his ever-obedient architect John Nash was hauled before the courts to explain the stupendous overspend. He was eventually acquitted, but Nash, who rather hoped for a knighthood, and instead that his career had come to, well, a humiliating end. Eventually, a reluctant Parliament paid up, and building work on the palace was finished, complete with a triumphal arch at the front.
