Hans Place dates from the 1770s, when the architect Henry Holland leased from Earl Cadogan and funded the building of his house by laying out a square which he sub-let in building plots. The octagonal shape of the square is thought to have been modelled on the Place Vendôme in Paris. Horwood’s Maps of 1799 and 1813 confirm that, with the exception of Nos. 55–56, all of the lots had been developed by the first edition, and that the final two houses were complete by the second.
