“Mother went in to work tonight, how I hate her on Sunday work!,” wrote fourteen years old Kathleen Biddlecombe in her diary, on Sunday, January 13, 1918. Kathleen and her family lived on 6 Cobbett Road, London, in Well Hall Garden Suburb—mostly known today as Progress Estate. Built between January and December 1915, in the first year of the First World War, the estate provided some 1,086 houses and 212 flats for the munition workers of the nearby Royal Arsenal factory in Woolwich. This article examines the First World War history of this housing project, by focusing on the diary of young Kathleen. Using the works of Henri Lefebvre and Michel de Certueau, the article probes the tensions between the ways this space was planned and built—in accordance with the agenda of the Garden City Movement—and the ways it was produced and used by its inhabitants during the war. It uncovers the production of space by the people whose houses were built along the Well Hall Road, where Route 44 of the Tram stopped to take them to and from the munition factory.
