Hans Place, London, England, is a residential garden square situated immediately south of Harrods in Chelsea. It is named after Sir Hans Sloane, 1st Baronet, PRS (16 April 1660 - 11 January 1753), who was a physician and collector, notable for bequeathing his collection to the British nation which became the foundation of the British Museum. President of the Royal Society and of the Royal College of Physicians of London, he also invented drinking chocolate and gave his name to Sloane Square.
Hans Place dates from the 1770s, when the architect Henry Holland leased 89 acres (360,000 m2) 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.
The houses were let on 99-year leases, and apart from assumed modernisation from time to time, appear to have remained unchanged during this period. The 1862 Ordnance Survey, for example, shows that none of the houses had been extended over the gardens, and annual directories record good tenancies with no obvious gaps during which major works might have been undertaken.
Most of the 18th-century houses in Hans Place were substantially rebuilt by Cadogan Estates when new leases were arranged in the late 19th century; (adopting a style that became so closely associated with the district that Osbert Lancaster dubbed it “Pont Street Dutch”).
22 Hans Place formed the headquarters of the 1921 Irish Treaty delegation. The delegates were Arthur Griffith, Robert Barton, and Michael Collins; Secretary to the delegation was Robert Erskine Childers who was also Robert Barton's cousin and father of the Fourth President of Ireland Erskine Hamilton Childers. Famously, it was at 22 Hans Place that, at 11.15 PM on December 5, 1921, the delegates made the historic decision to recommend the treaty to the Dáil Éireann; the negotiations finally closed with the signing of the Anglo-Irish Treaty at 2.20am on December 6, 1921.
During World War II, Hans Place received bomb damage and substantial repairs were required to many buildings, and where buildings were not repairable new development took place, particularly on the Pavilion Road side.
Hans Place was the scene of a murder in 1983, when actor Peter Arne was battered to death in his flat, apparently by an Italian vagrant who committed suicide shortly afterwards.
Hans Place now represents one of the most sought after residential addresses in Chelsea. International business executives, and the Super-rich, are particularly attracted to Hans Place because it is the garden square with the closest proximity to Harrods, and the best shopping in Sloane Street, Chelsea, and Belgravia.
Hans Place enjoys some of the highest levels of street security in London, being situated close to two police facilities serving nearby embassies, luxury hotels, and shopping in Knightsbridge and Chelsea and all of the private security arrangements maintained by, and for, Harrods and its customers.
