We were appointed to support the Geotechnica team based in Santiago Chile to provide specialist design advice for 3 projects at Alto Hospicio, Rancagua and Iqueque. The sites were spread across a number of climatic zones through north and central Chile. Each facility was designed to accommodate 3000 inmates with a wide-ranging mix of groups. In response, we developed concepts for house block communities containing education and training within them. We were challenged by the need to bring large groups of visitors into the heart of the prison which was a culture of the Chilean prison regime
