Since the last quarter of the past century, many developed/developing countries have attempted to restructure major cities, leading in terms of industry, history and culture, depending on changing socio-cultural, technological and economic dynamics. İn that restructuring process, laid-depression areas in the city centers usually have been reintegrated into the city in the way of of physical, economic and social sense via urban regeneration projects. Until the 1980s, the physical renovation oriented applications mostly have been made in the context of urban regeneration policy. İn case after 1990s, 'sustainable urban transformation' concept has emerged which based on economic development, social justice and environmental protection objectives. Therefore, in today's urban transformation experience, not only the contents defined in the context of physical-space but also performances depending on the components of sustainability and governance are extremely important for the success of projects. In this context; there are two main questions: “how would a systematic organization between actors in the process of projects?” and “how to interpret the physical dimensions of the conversion as well as social, economic and environmental parameters?” and answers of these questions is really important.

The effects of the above-mentioned processes may be evident in major cities of developing countries and Istanbul is not an exception of this matter. Istanbul, as one of the most vital cities all over the world, has involved “urban race” after 1980s. However, during this period, generally renewal and revitalization projects were realized. As the 2000s, despite a very large-scale urban projects came up in the upper-scale master plan, many of the recommendations set out only predominantly spatial transformation and could not find a chance to practice. Latterly, some of the large urban projects examples, which found a chance to practice, incorporates new participatory organization approaches however it is seen that this association schemes didn’t cover all stakeholders. This matter is regarded as a commencing point of this paper. It investigates the participation’s indisputable role in the process of sustainable urban projects. In this study, it is hypothesized that project implementation process, which can not ensure all the stakeholders participation, exceeds the optimum time and failed. These processes may be seen in Kartal case clearly, situated in one of the depression areas in Istanbul. As for methodology, Kartal transformation project projection and current process are determined and identified whether all stakeholders in the settlement participate the project stages equally or not.
