The quality of unity of opposites in the visual enhancement of Yazd Traditional Houses

Complexity and conflict are some of the strategies to increase visual diversity, which is less considered today in the context of extensive construction and adherence to the universal, inclusive model. This issue has led to long-term boredom in contemporary homes. However, the factors of contradiction and complexity are seen in the visual diversity of traditional architecture. In this way, the set of opposites as a strategy for creating some visual difference is one of the essential items that can reduce architectural space's uniformity. In this regard, since the utilization of the contrasting phenomena has some different consequences in architecture space organization (from positive to destructive impact) so, it must be evaluated in a valuable physical environment where this concept of conflict is well traceable. One of the most useful settings can be considered to be a case study for assessing the utilization of the opposite phenomena, is the traditional architecture in Iran. This architecture is full of exemplars that can be useful for learning architectural design. In this research, because of the undeniable quality of traditional houses in Yazd, these houses selected as research case studies. What follows in this discussion is a qualitative assessment of the traditional homes for finding the kind of the opposite phenomena and the process application to use them. In this study, the research method is based on grounded theory, and the field information was collected in two sections: open interviews and observations. The results of this research show that Structural and visual elements of the traditional houses in Yazd consist of the positive association of conflicting elements that you can experience in different situations. The results of this study indicated that the physical and spatial structure of traditional houses in Yazd had provided conditions where one can experience a positive association of opposites in different situations. In this process, it was found that the types of opposites that can be classified into four types of sensory, perceptual, visual, and symbolic contrasts increase the best understanding of the phenomenon, respectively, balance the totality of space, increase diversity and increase the semantic load of space.
