This study examines the roles of AI, 3D imaging, and augmented reality in the documentation and reconstruction of earthen architecture in Diriyah (Saudi Arabia) and Al Ain (UAE). Undertaking a preliminary study within the framework of the theory of environmental adaptation, the study shows the role of new technologies in the preservation of heritage. The study analyzes how emerging technologies such as photogrammetry, LiDAR, and BIM are used respond in the generation of precise digital twins of heritage sites, with the incorporation of AI and machine learning enabling deeper insights into the data. It further examines the role of augmented reality in public outreach and education about the sites and virtual reconstructions of the sites. The findings stress the importance of the inclusion of AI workflows to earthen architecture, which enhances its preservation, cultural significance, and scholarly inquiry and community heritage projects. Then study concludes with recommendations to the heritage community, educators, and policy makers about the widespread adoption of digital intelligent tools for sustainable preservation of the Gulf and the Arab world.
