This paper describes a research to develop new urban design alternatives for Gaziantep by using fractal based approaches. The aim of the research is not only generating new form alternatives but also considering the continuity of traditional architectural and urban pattern which faces deterioration. Within this study, it is intended to test the applicability of the fractal based generative approaches and explore the potential advantages. The method called CADaFED (Ediz, 2003) is updated to be used in one of the 3d modeling programs, 3DsMax scripting and it is used as an experimental tool in two-day student workshop. The working field is limited as Bey Neighbourhood in Gaziantep for its well-preserved architectural characteristics. In this paper, the outcomes of the student workshop will be evaluated and discussed in the sense of affirmative effects of fractal based design approaches.
