Gaziantep'in tarihi kesiminin yaşanabilirliğinin geliştirilmesi için stratejik bir yaklaşım

City's identity can be represented by architecture and historical heritage, it is where we can recognize how the city's founders have established and lived. Through the years and according to the continuous development, the architectural heritage of Gaziantep historical quarter had lost its capability to serve current modern life requirements and became unliveable. The thesis argues that, the livability with its comprehensive meaning varies according to cultures, living circumstances, time, economic, social life, and environment. Many efforts were produced to conserve architectural heritage and make it as possible kept up with modern life demands, although these efforts the historical quarters' environment still not enough to be lived in. In some cases, these restored parts were hiding behind them many dilapidated and unauthorized buildings, which represented duality in value and livability. This study aims to eliminate this duality and improve the livability by evaluating the livability environmental criteria of the historical quarters of Gaziantep city according to common indicators in the literature review and previous studies, by observation and questionnaires, which aim to take in consideration people's experiences in living within these quarters and spot the light on the important urban indicators of livability environmental dimension. The results of this evaluation will contribute to determine whether these quarters require radical new urban plan or rehabilitation and restoration plans are enough to fill the gap with present time living needs.
