The way Infrastructures, urban forms and the nominal green are put into relation is one of the key parameters which participate in the exacerbation of the issues presented in peripheral districts of major cities . Urban morphology takes on a crucial role in the definition of urban integration, especially within fragmented and very dense cities. Sharing a set similar needs - growth, space, and maintenance - ecologies and cities should be overlayed in order for each to help the other growth. Peripheral areas should therefore be activated by a sequence of purifying ecologies that create a new set of relationship between landscape and new programs. In order to respond to these issues, a megastructure which would act both as a synthetic city and as a synthetic forest will be developed. This synthetic city answers to pressing ecological and environmental issues. In fact, this project aims to challenge our current way of living, and the current definition of “ ecology”, by questioning and transforming the relationship between the “landscape” and the “urban”. Starting at a small scale in Ortica, Milan, the project will work towards the development of am organic urban prototype which challenges the way we build and understand ecology.
