Hong Kong urban environment is strongly characterized by super-density features, namely representing a problem In terms of liveability and space quality. This thesis elects the city as a research lab to inquire into urban density issue, both on a theoretical and strategical level. Indeed the argument is composed by two parts. The first one deals mainly with Hong Kong as urban entity, trying to analyze its features under different point of views; conversely the second one focuses on Kwun Tong district, an underdevelopment urban fragment that acts as micro-scale city mirror. The former section looks at understanding current urban circumstances and how the city became a super dense metropolis.
