Moreover, this book aims to provide concrete examples for designers to get to know how to integrate these principles practically into design and implementation process. In this framework, the debate on the definition of urban design has been put forward. The historical development of urban design has been presented in order to understand the past experiences and attempts in creating ?successful'' urban space. The principles of urban design, which are crucial to develop a key model for designing the urban space, have been used to monitor the projects from the Netherlands and Turkey with making comparative study between them. As a consequence, importance and necessity of urban design principles in order to create successful urban space and the importance of urban design for the future of the cities has been presented.
