Abstract
Purpose This study examines the built environment in the preserved historic settlements of the Najd region of Saudi Arabia, providing insight into shared core concepts and forms that were commonly shared across the settlement's dwellings before the Kingdom's period of modernization. Design/methodology/approach Space syntax convex mapping and the justified access graphing as the main techniques to examine several internal elements at the building level. The study created elements such as connectivity, access graphs and depth graphs to understand the integration and placement of these elements to overcome surrounding forces. Also, the author combined graphical architectural analysis with space syntax techniques to understand the spatial and physical integration in three-dimensional space. This helped to establish a link between what is two-dimensional (the building layout) with what is three-dimensional (the physical form). Findings The paper found that the hierarchical order of internal spaces and the order's role in shaping the physical form served to satisfy the social behavior and environmental conditions. As a result, all building elements generated with the guidance of the main culturally rooted in support with internal spaces order. This order of spaces inside the house led the urban spatial hierarchy to connect but not conflict, as the whole process of generating the physical forms is to complement each other and to produce a unified built environment. Research limitations/implications This study is limited to Najdi dwelling form and culture, the author believes expanding the number of study samples in the five traditional settlements or expanding the scope of the study to examine other Saudi regions may result in new findings and insights. Originality/value The paper offers and discusses two mechanisms on how to enhance the process of designing modern houses in similar cultures or elsewhere in the world. Also, how traditional dwelling elements generated with the guidance of the main, culturally rooted values and beliefs, in support of the internal spatial order.
