Past resettlement projects often turned out to be ineffective: the resettled households were not satisfied with their living conditions in the new location (due to insufficient financial support for construction of houses there, inappropriate quality of soil in the allocated land for agriculture, lack of employment opportunities, etc.) At the same time, there remains the problem of previous spontaneous individual housing. The Master Plan of Dushanbe (approved in 1983 and adjusted in 2010) provides for demolition of tire "kibit" buildings made of traditional cob material in the central part of the city, which have total floor space estimated at about 750,000 nr, with an eye to using tire land for construction of multi-storey residential buildings.
