This book explores what it means for development activists to practise architecture on a global scale, and provides a blueprint for developing architectural practices based on reciprocal working methods. The content is based on real situations – through extended field research and contacts with architecture schools and architects, as well as participating NGOs. It demonstrates that the ability to produce appropriate and sustainable design is increasingly relevant, whether in the field of disaster relief, longer-term development or wider urban contexts, both in rich countries and poor countries.
