Resumen de Replacing “mixed use” with “all mixed up” concepts; a critical review of Turkey metropolitan city centers
Following industrialization and modernization, globalization has asserted itself in the daily life and spatial practices at the end of the 20th century. Instead of a zoning approach separating the city from functional aspects, the “mixed-use” approach was been brought to the agenda in order to have inclusive design and sustainable city centers. The new mixed-use business areas in the İstanbul, Ankara, and İzmir metropolises constitute the focus of this study. Within the scope of this study, analyses were performed in order to examine effective dynamics from an urban scale to a housing scale. In the first stage, the planning processes of central business areas and the development of “mixed-use” approaches were investigated. Eight parcel-based structured and five area-based structured mixed-use projects were analysed, and the regional structure and dynamics were discussed. In the last stage, the projects were analysed in detail according to their functional programs. At the end of the present study, a mixed structural approach is suggested for decision-making, planning, and design implementation processes resulting in projects which will be developed in central business areas offering sustainable development and improvement. In this approach, termed “all mixed-up”, it would be possible to design affordable housing for low-income inhabitants and at the same time revive urban regions with mixed-income users, developers, and governmental institutions.
