Explaining the concept of transparency in Qajar architecture with the approach of morphology of traditional houses

Transparency is one of the principles that has been continuously used in Iranian art and architecture. The meaning of this principle in Iranian architecture is the constant movement and evolution of material quality to spiritual quality. The current research is analytical-descriptive research in terms of its structure, which in terms of its main goal is considered to be of the type of applied and developmental research, which can also be used as an exploratory research approach considering the lack of previous research on the concept of transparency in the field of the city in a methodical way. According to the course of theoretical foundations, the effective factors in the influence of transparency in the field of traditional houses morphology and by explaining the branch of Qajar architecture style to it, these factors are gathered for indexing using content-analysis method are taken so that the framework of the proposed criteria can be presented in chapter one. In conclusion the main affecting factors are enlistment, spatial ambiguity, flexibility and compatibility, legibility, permeability, spatial perception, connection, connectivity, spatial organization, spatial opening, dynamism, lightness, sequence, visual connection and light transmission. In future studies the main factors can be evaluated about relationship and affection value in traditional house architecture.
