Ebenezer Howard
Suburbanisation in the interwar period was heavily influenced by the garden city movement of Ebenezer Howard and the creation of the first garden suburbs at the turn of the 20th century. The first garden suburb was developed through the efforts of social reformer Henrietta Barnett and her husband; inspired by Ebenezer Howard and the model housing development movement (then exemplified by Letchworth garden city), as well as the desire to protect part of Hampstead Heath from development, they established trusts in 1904 which bought 243 acres of land along the newly opened Northern line extension to Golders Green and created the Hampstead Garden Suburb. The suburb attracted the talents of architects including Raymond Unwin and Sir Edwin Lutyens, and it ultimately grew to encompass over 800 acres.
