The architecture of Qeshm Island includes the specific architectural style of a warm and wet area,which previously had a functional use aimed to reach a sustainable architecture and development.However,few studies on the identification of the characteristics of vacular architecture and their roles in island stability have been performed.Thus,to understand the vacular architecture of the island as a sustainable patt,we discussed it separately in three aspects,namely,urban fabric,one-based architecture,and architectural details.To address our study,a part of the old fabric of the city with its existing buildings (42 buildings of 70 years of age) was selected and evaluated in a qualitative study.Results showed that in the scale of the urban fabric,factors,such as the structures of the buildings,the frame of the neighborhood spaces,and in terms of the architectural details,factors,such as bars,thickness of the walls,and the openings,are among the vacular features of the area,playing an important role in the stability of Qeshm Island.In general,studies showed that vacular architecture of the island has focused on developing an orientation between the climate of the region and a good understanding of the construction.
