Investigation of the spatial desirability of traditional houses based on functional efficiency components (Case study: Qajar Houses of Yazd City

Iranian traditional houses are an example of native housing that has different key characteristics and functionalities. Mass and space in these homes have been shaped for a variety of reasons, including climate, cultural relations, social features, and so on. Other factors also contributed to the formation of different species of this indigenous housing, because the structural and spatial formation of this type of housing in addition to the climate can be affected by functional characteristics, and this can have a significant effect on the functional and functional quality of this have homes. Therefore, the purpose of this study is to investigate the performance and the role of the courtyard in traditional homes and examine them in these houses. In this regard, optimal space efficiency, spatial integrity, motor circulation, permeability and spatial flexibility in homes are defined. In order to determine the effect of the number of the yard on this spatial desirability, first Yazd case samples were selected based on the number of yards (1 domain, two domains, and several domains). The tool used to analyze homes is the space syntax, which uses spatial graphs to analyze the spatial relationships of the house. The results show that houses with a central courtyard that forms mass and space around it has more permeability (less relative depths than two domains and several domains) and also flexibility And has a higher spatial connection than other examples. Also, due to the more appropriate access and the more effective communication of these spaces in a dwelling house, these houses have a greater spatial utility than other samples.
