Investigating the Syntactic Codes of the Qajar Period Houses of Yazd from the Semiotic Point of View (Using the Space Syntax Method)

The houses of the Qajar period of Yazd have many historical, cultural and architectural values as architectural texts comprising signs and codes, as the main propositions of traditional architecture. Perception and discovery of the hidden secrets in architectural texts is achieved through reading and through semiotics. This research has explained the syntactic codes as one of the semiotic codes using the space syntax method. First, in-depth studies were carried out in the field of theoretical foundations and the influential components and indicators in space syntax were identified, and then a number of ten bab houses of the Qajar period of Yazd were tested as selected samples for reading and analyzing the spatial structure, based on the space syntax method. The upcoming research analyzes the syntactic components of the spatial structure through a case study in two parts of field studies and Depsmap software to discover the syntactic codes of the selected houses. In this analysis, the samples are measured based on the components of interlinking, relative depth, visibility, entropy, and visual connection, and after analyzing data and field studies of space syntax, results lead to the discovery of syntactic codes of houses. The results show that the syntactic codes of these houses are explained in the form of concepts and meanings derived from the relational systems of the texts, based on spatial hierarchy, cohabitation, order and disorder, mystery and secrecy.
