Değişen kent formları, mekansal algılar ve ilişkiler: Sıhhiye Ankara üzerine bir okuma

People subconsciously communicate with their environment. When interruptions concerning the reflection of citizens, culture, and daily routines on an urban place which can also be called a social product have begun to surface, the establishment of communication between the place and its users can be asserted to have become a failure. Consequently, the place's users do not clearly perceive the urban place; accordingly, the urban place loses its semantic value over time. The aim of the thesis research is reading a place spatially to understand how urban forms change and pose effects on human behaviors. Sıhhiye, Ankara, which is both stratified as an urban form and in terms of its sociological structure, and has a historical value in urban memory, was decided to be analyzed as the case area. Both conventional methods; iv photographic analysis and map reading which help to analyze and understand historical developments, interventions, and to make sense of spatial peculiarities of a hundred-year period, and a modern method, space syntax, a computer-based approach to analyze today, were employed to spatially read the site; Sıhhiye, Ankara. These methods helped to perceive the site from different perspectives to draw objective conclusions signifying the process through which the space has lost or preserved its semantic value via the process of spatial reading. Through the implementation of these methods, the spatial perception and transformation of the site was analyzed, and urban potential for the city was revealed. The findings drawn from the analyses set forth that Sıhhiye Square and its surrounding environment have lost their historical spatial value, and that although it once served as a gate to Yenişehir where the square had strong communication with people, the thesis shows that the site started to lose its characteristics as a "gate" and evolved to become an ordinary part of the city due to the spatial arrangements made to speed up traffic owing to the effect of increasing population and technology during the years that followed. According to the space syntax results, the area still has the potential to become pedestrian friendly and in terms of transportation, it can be considered not only as a hub, but also as a place where the city and citizens can have a breathing space. Consequently, Sıhhiye Square, which constantly reproduces, can be replanned in a way that it will both preserve its heritage and respond to citizen's needs, retaining; and even increasing its easily perceived spatial identity.
