The politics of spatial reproduction have been at the heart of Turkey’s economic growth over the past two decades, accelerating rapid urban change in İstanbul. In addition to the transformation of the existing building stock in the city, natural spaces are also being developed through the partial revision of master plans and reproduced through large- scale new investments. This study examines the spatial changes in the Ayazağa Neighbourhood on the northern periphery of İstanbul. The region has become one of the areas where large capital owners have invested extensively in the last decade. Most of the new spatial interventions are large- scale mixed- use buildings. Based on morphological analysis and in- depth interviews with residents, the study investigates the existing urban fabric and the new interventions through four specific cases. The reproduction of urban space in the case study areas is discussed in terms of spatial characteristics and social aspects. As a result, the lack of public open spaces, massive new buildings with privately owned public spaces, and the social and spatial segregation between the residents of the informal settlements and the new upper- class housing are addressed as problem areas.

This study examines the evolution of Philadelphia’s city block morphology between 1683, when the city was planned by William Penn, and 1900, when urban expansion abandoned the grid. The study uses both quantitative and qualitative assessment. The city grid underwent evolution during this time that resolved deficiencies of the original Penn plan, improving circulation and maximizing block area for rowhouse development. The Penn grid had large rectilinear blocks with irregular dimensions: it experienced two types of evolution. The first was adaptation through infill, as large 1683 blocks were subdivided by secondary through streets and tertiary streets. The second was adaptation through expansion of the grid, first an irregular, ‘unplanned’ grid, and later a regular, ‘planned’ grid. Both expansions reduced 1683 block depths to permit additional east-west circulation and to increase developable block frontage. Mean block depths of 666 ft in the Penn grid were reduced to 383 ft in the adapted grid, to 328 ft (south) and 393ft (north) in the unplanned expansion grid, and to 422 ft (south) and 534 ft (north) in the planned expansion grid. In the expansion grid, tertiary streets and rowhouse dimensions and heights were integrated with quaternary streets (pedestrian alleys), permitting high levels of housing density and diversity.
