Medellín – Life Articulated Units programme

25 August 2020

Discover how Medellín turned neglected water tank sites into vibrant community spaces, built with residents at every step.

Once the city's dark spots that draw violence and crimes, some 20 inaccessible water tank compounds in the heart of Medellín’s neighbourhoods are transformed into inclusive community venues through a participatory design process from concept to operations.
