The houses in Eaton Square are large, predominantly three-bay-wide buildings, joined in regular terraces in a classical style, with four or five main storeys, plus attic and basement and a mews house behind.
Before World War II Eaton Square was a securely upper class address, but not of the grandeur of London's very grandest addresses in Mayfair and Belgravia: Belgrave Square, Grosvenor Square, St James's Square or Park Lane.
