Materials found locally are the most common disposable resources found in large quantities in different geographical areas, at certain times of the year. However, depending on the climatic season, certain materials are more abundant than others. This is due to the different bioclimatic zones across West Africa. This thesis critically appraises some of the local materials available in West Africa that are applied in vernacular techniques. The study involves the analysis of materials such as hemp, cork, bamboo, brick, stone, timber, and mud. These materials are relatively more economical than the materials imported into the country. Even though there is incremental demand for foreign materials, this should be discouraged, as it neglects the available traditional materials of West Africa. The thesis also focuses on the sustainability of these materials and techniques used to practice, which can serve as alternatives for architects and manufacturers in the industry.
