A 75-year old informal community on the Buenos Aires waterfront is the city’s most celebrated barrio. Imagine an unprecedented process that transfers land title to those who built their homes by hand; a new place-specific building code and building retrofits to establish public safety and the reimagination of a freeway fly-over into a new civic space. A “build first” strategy of over 800 new units of housing ensures all families are able to remain within the community as a gritty industrial waterfront is slowly transformed into Buenos Aire’s newest waterfront neighborhood.
