Since not far past up to now, immigration from all over the country to Tehran, irregular growth of urban population, inconsistency with urban infrastructure development, environmental pollution and low quality of living areas, erosion of self -growing fabric in most areas which get erosion very quickly due to not being benefited from minimum constructional standards, service and urban infected organ are all those problems that a city such as Tehran is confronted with.
Any city is generally originated around one or a few cores which by passing time and attracting the population through increasing the cores and establishment of new districts and expansion of primary cores, the urban area will be extended and accordingly Tehran cannot be naturally excepted from this trend.
In northern areas of the city, in addition to the erosion of fabric of primary core which are rural centers of Tehran expansion, as well as low standard levels, we also confront with a more serious problems and that are neighborhoods of these eroded districts with renovated areas which have been increasingly developed by different urbanism indicators in a particular facade with construction materials, and social-economic classifying of dwellers viewpoints during seventies years that can be interpreted of schizophrenic appearance of Tehran.
The reasons why these areas have been chosen for residence -Tehran attractive power and immigration of countrymen to the city, due to economic (in particular unreal jobs) and cultural possibilities and consequently their housing requirements are some of main reasons -Rapid increasing of population, immigration and conformity of land price in these areas with financial power of low-income households and above-mentioned dwelling conditions, have promoted demands for residential units in such areas.
