This article analyses the development of Neolithic earthen architecture in the Eastern Mediterranean as a concrete example of ‘communities of practice’. Recent studies on earthen architecture have highlighted its adaptability to different climates, architectural forms and craftmanship levels, focusing on the technological aspects of earthen construction. This paper explores the anthropological significance of earth as a building material. It provides evidence on the development of earthen building techniques, interactions between different communities regarding building practices and an understanding of the dynamics of chaîne opératoire in relation to various materials. A review of archaeological case studies provides compelling preliminary evidence for the existence of early specialized architecture in Neolithic Aegean contexts.
