situational topography, thesis in landscape urbanism at the AA*The masters thesis in landscape urbanism is situated in East London where the 2012 Olympics will take place, in an area of industrial waste, obsolete infrastructures, and generations of unemployed.The project proposes to stitch the margins of Lea River through an urban-environmental topography as a sensible system over the site. The urban project was generated through housing prototypes that adapt horizontally to degrees of contamination in the soil and vertically to economic potentials. The combined matrix of 1´000 variations generates different prototypes without aesthetic prejudice, and promotes different social organizations. The urban topography generated by the self-organization of prototypes is tested in a sector of the site through vectors in a process of systematic adaptation reacting to the nearness of environmental qualities, movement patterns, and transport infrastructures.The urban pattern of occupation is the tissue that articulates systematically and sensibly the urban matrix generated by the existing constructions, Lea River, the Thames, subway stations and railroad lines.*This project was developed as part of the Architectural Association master in Landscape Urbanism, 2000-2001
