The 90% of the global population growth in the next 30 years will happen in developing countries, where the urban population rise will create increasing issues related to informal settlements and growing inequality. Improving the health conditions of the built environment and reducing the related risks will be a crucial challenge for future urban professionals. This paper is aimed at describing a learning experience built as a workshop for students, in which they designed a social facility modular system for developing countries, inspired by the organic and hypogeum architecture principles. The result is a list of guidelines for the design of similar functions, that should help a conscious construction process to reach some fundamental sustainability goals
