How can we apply constructive experiments in architecture as an innovative response to the climate crisis? The conference ‘Constructive Disobedience’ was dedicated to addressing this question. This book compiles various projects and positions presented there, drawn from a wide range of practice, teaching and research cases. International projects include a prestressed rammed earth structure, studies on heterogeneous constructions, and the rediscovery of natural materials such as hemp and lime. Together, they form a methodological foundation that highlights the knowledge gained from experimental architecture for the coming era of building transformation.
