Ethnicity is one of the cultural characteristics of immigrants that can affect the housing structure. As such; the housing structure for immigrants is a space to strengthen identity, meet basic needs, and maintain contact with their ethnic roots. Meanwhile, the housing of immigrants with different ethnicities is often based on the culture of the ethnicities in the host city and does not correspond to the real needs of immigrants. Therefore, analyzing the housing structure of immigrants is an appropriate response to adapting these houses to their ethnic needs. The aim of this research is to identify and examine the impact of ethnicity on the housing structure of immigrants, which is carried out using a descriptive-analytical method with a comparative approach and conclusions based on logical reasoning, in an inductive manner. Data collection was carried out using two techniques: documentary-library studies and field collection through observation tools, targeted interviews, photography, and plan review. The findings indicate that the ethnicity of immigrants has caused changes in their culture and needs, and has caused the most changes in the structure and location of the housing of immigrants in Golshahr neighborhood. The reproduction of spatial organization in the immigrant house shows different plan structures, changes in the way of arranging space from public to private, different organization of living and dining areas, the amount of open and closed space, how to create visual privacy, different determination of the location of housing spaces, and different location of the guest reception space, which is most related to their ethnicity. Also, according to the findings, it seems that there is a direct relationship between ethnicity and determining the location of housing. As immigrants choose a neighborhood for residence where they have the most connection with their ethnic groups.
