Now it’s time to get granular.

We asked five writers to really dig into organisations that are doing the messy, joyful and complex work necessary to transform their cities.

Each folio traces the history and context of one particular project, the principal people involved, their operating model, their successes and failures.

The projects are: Sihlanzimvelo’ Stream Cleaning Programme, Durban, Indian Institute for Human Settlements, Bangalore, La Granja Transfonteria, Tijuana, Library Parks System, Medellin, and Seme City, in Benin.
