While structures are necessary to meet housing needs, on the other hand, the construction industry consumes a great quantity of resources, creating a problem that is global in scale. Supplying the materials, processing them, and transporting them to the construction site create significant environmental problems. Therefore, to reduce waste, preserve resources, and increase energy efficiency, an ecodesign approach is now being considered. Earthen structures have played a significant role in the development of human civilization, both functionally and symbolically. These structures represent a crucial part of architectural heritage in terms of adaptability, cultural expression, and sustainability potential. As contemporary challenges such as climate change and urbanization intensify, the lessons offered by earthen construction techniques can illuminate future building methods and contribute to a more harmonious framework for the human-nature relationship. In this study, earth structure techniques used in building since the early ages and modern earthen techniques, like rammed earth structure, were analyzed. The rammed earth construction technique (RE), with its deep historical roots, holds a significant position among sustainable, eco-friendly, and cost-effective building methods. Traditional earthen construction techniques have contributed to cultural heritage preservation through local material use and community involvement, while modern approaches have integrated material innovations and technology. To promote sustainable building practices, it is essential to develop dedicated regulations for RE, enhance educational initiatives, and increase the visibility of successful projects. These measures will facilitate the wider acceptance and implementation of RE as a key solution for sustainable and resilient architecture.
