Prolific early 19th century architect Sir John Soane designed many public buildings in London including, famously, the Bank of England (since considerably altered) and the somewhat revolutionary Dulwich Picture Gallery. He also designed a number that were merely fanciful works and never commissioned nor constructed.
Foremost among them was a sprawling royal palace which would occupy part of Green Park off Constitution Hill.
While Soane had been designing royal palaces as far back as the late 1770s when in Rome on his Grand Tour, in 1821 he designed one, apparently as a new home for the newly crowned King George IV.
Birds-eye view drawings show a triangular-shaped palace with grand porticoes at each of the three corners as well as in the middle of each of the three sides. Three internal courtyards surround a large central dome.
Despite Soane’s hopes for a royal commission, the king appointed John Nash to the job of official architect and so Soane’s palace never went any further than the drawing board.
He also designed a grand gateway marking the entrance to London at Kensington Gore through which the monarch would travel when heading to the State Opening of Parliament in Westminster – it, too, was never realised.
