I lived in Caracas as student during 2008/09. Caracas is a special case regarding the progress of shanty towns. How regions "grow" without supervison and design,it is quite impresive. It is this kind of improvisation that makes places like" torre david", "San Agustin" or "Petare" so special. It lead to one particularly question: What is the rule of architecture? Architecture is not service. This book helps to understand the social architecture of Barrios.
