Modelling the built environment: Spatial patterns, siting techniques and layout works of non-monumental architecture in Early Bronze Age Eastern Arabia

Interest in the built environment of Early Bronze Age (EBA) Eastern Arabia is rapidly increasing with the emergence of new field data from the excavation of settlement sites. However, little is known about architectural planning and spatial patterns in the region. This article explores non-monumental architecture throughout the third millennium BCE. A series of methods (Pythagorean triples, modular grids, interception of circles) were used to assess the geometric and metric characteristics of buildings, and to stress regularities and variation in the long term. The results of these analyses suggest the application of specific techniques in layout and construction works: the intersection of circles during the Hafit occupations, and more sophisticated techniques, combining the properties of circles and triangles, during the Umm an-Nar period. The diachronic approach allowed by the temporal span of the occupations highlights a firm progression of architectural paradigms and building crafts throughout the EBA. The evidence hints at the existence of a specialised workforce since the dawn of the Bronze Age, and reveals a sharp increase of technicity and standardisation towards the end of the third millennium.
