Campden Hill Square is a residential square consisting of large family houses.
In the Tudor period there was a farm called Stonehills, 20 acres in area, south of what is now Holland Park Avenue. It came into the possession of the Lloyd Family who sold it in 1823 to a developer, Joshua Flesher Hanson.
Hanson designed a square similar to Regency Square which he had built in Brighton in 1818. The new square provided terraced houses around three sides of a large garden enclosure.
Campden Hill Square was originally called Notting Hill Square but the name was changed to Campden Hill Square in 1893. It slopes steeply down to Holland Park Avenue.
