This paper describes the process of materials selection, design and construction used for a series of small residential buildings in Southern France. Whenever possible, materials were resourced in situ in order to minimise the environmental impact of the new buildings. In particular, the process of materials selection, stone masonry with stabilised in situ soil mortar, and the form of construction are outlined. Guidance for a more generalised adoption of the design process is also provided. The energy consumed in the building of one house is compared to a typical concrete house. By adopting local materials the amount of energy used in building decreased by up to 215% and the impact of transportation by 453%. However, adoption of local materials in developed countries can be hindered by the loss of traditional building crafts and a lack of appropriate building standards. These problems are also discussed in this paper.
