This feature is recorded in the English Heritage Historic Area Assessment for Cliffe Parish. The report states: "The late 19th century population growth of Cliffe created a demand for housing on an unprecedented scale. Most of this demand came from workers at Francis & Company's cement factory and early on the company provided housing for some of its employees erecting in the 1870s houses and cottages along Salt Lane, opposite the works. Census returns suggest that this housing did not cater exclusively for any particular type of worker, although a basic hierachy is clear, with terraced cottages housing labourers and their families, and semi-detached villas accommodating foremen and clerical staff. Perhaps for reasons of technical virtuoisity and advertisement, Portland cement concrete was used for one terrace (Nos 1-5 Cement Cottages) but otherwise brick was the material of choice. Francis and Company provided housing for only a small fraction of the workforce and speculative builders made up much of the shortfall in accommodation. …Francis and Cmpany provided some accommodation for its workforce including Nos 1 and 1 Cliffe Villa Cottages and Nos 1-5 Concrete Cottages, Salt Lane. The grandest house built by the company, Cliffe Villa, which housed a foreman at the works, no longer survives." (1)
