77 Questions about Architectural Space

Andrea Deplazes is a professor of architecture at ETH Zurich and a practicing architect. Internationally, he is best known for his book Constructing Architecture: Materials, Processes, Structures—a comprehensive handbook on building construction that has been translated into several languages and is widely used in architectural education worldwide.

This new book could be seen as the legacy of his teaching. Developed between 2017 and 2025 in the course Design and Construction I/II at the Department of Architecture, ETH Zurich, it brings together key questions, models, and sketches to explore the fundamentals of spatial design. The material is complemented by images from seminar weeks and excerpts from Deplazes’ personal notebook. It stands as a synthesis of his pedagogical approach and marks the conclusion of his academic career as he retires from ETH Zurich.
