An Analysis of the Physical Form Transformation Processes of the Old Texture of Kashan City

The old texture of Kashan is one of the worthy old textures that is confronted with physical, social and economical changes due to some difficulties such as the lack of suitable facilities, economic decline, physical and social wear, etc. Different encounters with the procedure of current changes and processes have caused the physical and spatial construction of the texture to change and while changing the form of the texture, it gradually reflects the undesired features of the new texture in itself and presents an abnormal appearance within the framework of the qualities of the organic texture. Therefore, in this research, the spatial physical processes were studied with an emphasis on the processes which change the form and appearance of the texture and the impact of the spatial set up and the finally old physical construction of the historical city on the procedure of the growth and development. For studying and clarification of this research, a combination of descriptive, analysis and survey methods has been performed. The consequences of the data analysis, clarifies that the masonry quality and the materials used in the building of residential masons, are the effective factors in form transformation and morphology and the physical transformation of Kashan old texture. So that more than 60 percent of residential masonry form 400 studied units in Kashan old texture area are destroyed and repaired, based on the quality and built of bricks and mud based materials. Also the study shows that the high building expenses especially in the center of the texture, lack of the appropriateness of the ancient transport bands with the modern needs and eventually the decrease in texture dependency among the youth and unaboriginal migrants are the most significant factors that play an important role in texture form and physical transformation.
