The concept of sustainable dwelling epitomized in the courtyards of Iranian houses: A case study of houses in Kashan in the Qajar period

Sustainable dwelling is a mental concept, yet it should meet the physical and emotional requirements of humans for living. Therefore, only those sites in which human needs are satisfied can be regarded as sustainable dwelling. Iranian traditional houses with their genuine characteristics are still something to be desired. In these houses the courtyard is the heart of the structure and at the same time it is counted as its organizing principle. Hence, understanding the function of the courtyard leads us to an understanding of the purpose of the whole building. This paper argues that the traditional Iranian courtyards are a materialization of the concept of sustainable dwelling. Moreover, the writer contends that probing into the courtyard for the concept of sustainable dwelling has the added advantage of shedding light on a solution to palliate life conditions in contemporary modern houses of Iran. To this aim the courtyards of three famous houses in Kashan, Iran during the Qajar dynasty, namely Borujerdiha house, Tabatabe'i house and Saleh house are examined as the closest historical examples to our modern world. This study the writer aims to provide a local definition for the concept of sustainable dwelling and second to suggest a practical solution by which to reach an ideal state of life in the contemporary world.
