This diploma consists of a book which documents the history of 120 Hours, a student-driven, global, architecture competition which was founded at AHO ten years ago. For its 10th anniversary I have gathered material about this competition, through archive work and interviews. I have invited key figures to write texts to contextualize this competition. And I have written a text on architecture competitions which is meant as an overview of the subject aimed at students. The main topics of this diploma are architecture competitions and architecture education. The ambition is that this book will be a relevant documentation of a part of AHO’s history which often remains invisible. And most importantly to inspire future students to engage in student initiatives in their education. I hope that this book will be a tool that new generations of students can use to develop 120 Hours further and that this will help the competition to survive the next decade.
