A pair of terraces on the Carlton House Terrace street took the place of this house. George IV was the Prince Regent likely to have stayed in that house in 1811.
Carlton House was a mansion in London, best known as the town residence of the Prince Regent for several decades from 1783. 
George IV (George Augustus Frederick; 12 August 1762  26 June 1830) was King of the United Kingdom of Great Britain and Ireland and of Hanover following the death of his father, George III, on 29 January 1820, until his own death ten years later. 
 From 1811 until his accession, he served as Prince Regent during his father's final mental illness. 
 They took the place of Carlton House, and the freehold still belongs to the Crown Estate.
