Studies on preparing the urban tissue against expected Istanbul earthquake has been going on in planned-unplanned housing settlements. Implementations so far have taken the form of renewal on one plot of land in general, and on an urban block in sometimes, causing intense inner city mobility issue. This paper aims to inquire into "place attachment" within the context of environmental quality, as in big cities, renewal processes seem to arise relocation problem of the residents. In this study, "place attachment" theme is examined over Kagithane research data related to undergoing urban transformation. The focused parameters are environmental quality, security, satisfaction, social bonds, in-situ transformation trends etc. The findings indicate a high-level place attachment. Residents interviewed have a strong sense of territoriality over their quarters; and they cooperate with the local authorities in solving their problems. Therefore, the residents' knowledge should feed into urban renewal policies. If in-situ urban transformation model is to be adopted by the local authorities, the priority should be given to the preparing a plan, inventorying building quality in the area, demolishing those buildings under earthquake risk in planned phases, and constructing affordable housing for the residents to remain in the settlement. Within the major goal of urban transformation law, implementations should improve life quality in the quarters and create liveable environments and the residents should return to their houses. Therefore, "place attachment" must not be neglected as part of renewal processes.
