[ES] Over time, the possibilities for construction with traditional techniques in Saudi Arabia have decreased considerably. Saudi Arabia’s new generation has forgotten traditional architectural and structural designs when building villages, cities and housing. The materials used in the construction of traditional structures have been replaced by more sophisticated building materials such as concrete, cement and glass. Sophisticated architectural and design methods often do not last for a long time due to the country’s climatic and topographical conditions, such as extreme heat and heavy sand storms. The revitalisation of the construction of traditional structures and architectures, together with the newly built technologies, will result in strong structures able to withstand the harsh conditions in the country. This investigation seeks to identify the most applicable structural construction methods that can be used in historic land-based buildings in Saudi Arabia for conservation purposes. This thesis addresses the importance of structural and architectural perspectives for the traditional buildings of Saudi Arabia. The thesis also analyses the point of view of the Saudi people with regard to the selection of building materials and the architectural styles frequently used. This investigation also examines the old techniques used in traditional Saudi Arabia’s buildings, how these can help in formulating a new approach to contemporary architecture and how they can be introduced into the current construction in Saudi Arabia. In preparing this thesis, a methodology has been used to meet the objectives set at the beginning of the study. The first step was to look at Saudi Saudita’s different ground architectural structures. This stage consisted of travelling to different locations to observe the structures and to conduct interviews with former builders. In order to gather more information on the topic, visits were also made to Yemen and southern Morocco, as in these two countries the land architecture has already been linked to contemporary architecture. The traditional architecture of Morocco and Yemen is similar to that of Saudi Arabia, but in these countries the new contemporary architecture has been developed later. Laboratory tests have been carried out to determine the relationship between the soil composition and the stability and robustness of the built structures. Empirical studies were also carried out to determine the compaction, strength, dimensional stability and permeability of building materials. These factors influence the choice of building materials for the preservation of traditional architecture and for solving the current need to build economic housing in today’s urban fabric. The results of this study indicate that the traditional construction techniques of the adobe and the cob (hand wall) are two of Saudi Arabia’s main techniques, each related to the particularities of the populations living in a given location. This view has also shown that the different architectural patterns were influenced by the functionality, comfort, efficiency and availability of the necessary building materials. This explains why different structural and architectural typologies exist in different parts of Saudi Arabia. This study concludes that linking traditional architectural methods with new technologies can serve to build more robust and long-lasting housing in Arabi.
