Present approaches to the city block in the context of the city structure

What is the role of a present form of city perimeter block in the complex system of the city? Current urban masterplans often include the compact city block forms, yet their realization is governed by different rules with different levels of impact and reflection of existing urban structure of the city. The research will focus on particular case studies of recently built projects of perimeter blocks in several european cities and what environment on the basis of current approaches and rules they are creating. Work will reflect both the current knowledge on the evolution of the traditional house block, and from the other side of the current knowledge of the properties of complex systems.
