This book documents the ideas and work of notable Canadian architect Barry Sampson, who was Professor of Architecture at the University of Toronto for nearly thirty years, and an instrumental part of the evolution of Baird Sampson Neuert, a significant critical practice in Toronto. The book investigates key ideas identified in Sampson’s 2019 Baird Lecture at the University of Toronto; documents three projects illustrative of Sampson’s approach to design; and collects reflections on Sampson’s diverse roles in architecture – teacher, practitioner, advocate, environmentalist, mentor, client, and builder – from notable architects, engineers, and academic colleagues.
