The requalification of the area of La Boca in Buenos Aires: a periphery along the river This Master Degree thesis deals with a peripherical area of one of the biggest metropolis in the world, Buenos Aires. The first step concerns the analysis of the urban conglomeration, its development and its actual problems, followed by a deeper scan of the neighborhood: La Boca, the first settlement of the city, is now located along the southern border and presents several problems, similar to all the occidental cities, trying to face the recent crisis and the consequential closure of all the factories activities that enhance the spread of empty places and the need to rethink these huge spaces to convert them into hubs for new functions, avoiding the expansion of the urban tissue.
