Yvonne Jewkes, Professor of Criminology at the University of Bath, talks to Laurie Taylor about the design of prisons and the importance of an architecture of hope which nurtures the possibility of rehabilitation, from Limerick to Norway. They’re joined by Lynne McMordie, Research Associate at the Institute for Social Policy, Housing and Equalities Research at Heriot-Watt University, whose research suggests that the congregate nature of hostels and shelters for homeless people often compound the problems of residents, rather than providing a safe space or route to secure housing.
