Ecotransitional Urbanism started with a research of new materials for the city with regards to performance and functionality. The project generated a rich base of indexes which traduce environmental, topographical and geographical parameters into a material ready to be use for the design. The proposition consists of a mesh as a model of density and diversity -within an urban framework- that seeks to understand, articulate, and visualize possibilities for the hyper dense, programmatic difference, and radically optimized new agglomerations in China. The site is threatened to become another generic Chinese urbanization that spread across farmlands. Signs of scarcity of water resources, deforestation, fish farming and industrial pollution are already present.
