The experimental policy process of Auroville, a city planned in 60’s by the French architect Roger Anger in the proximity of Puducherry, India, and endorsed by the UNESCO ever since. The site, characterized of a complete absence of vegetation, frequent wind storms and monsoon deluges which stripped it further of its meager topsoil, had been a dense forest in former times. Since 1968 the intense work of the earliest settlers has made possible the regeneration of this land and the eroded topsoil, where the city will expand and grow. Further advancements have been the alternative water supply and irrigation systems stemming from ancient techniques, as well as the planning of a low rise dense urban fabric characterized of solar passive protection and cross ventilation systems. This research and design work results in a series of urban fabric prototypes and urban design guidelines which help build this city according to the original plan. These are grouped in the following thematic areas: mobility, housing typologies, land use, development phases and green master plan.
