VOLUME 63: The Not-so-easy Guide to Circular Interior Design is organised into three levels of expertise – beginner, intermediate, and expert. This structure is linked to three in-depth circular interior design case studies featuring interviews with different actors involved in the projects. From clients to contractors, designers, architects, makers, sustainability accountants, and demolition crews, they all pitch in and share their learnings. Additional contributions delve into key findings and look in depth at circular calculation tools, developments in bio-based materials, as well as the role of cleaning and maintenance culture, financial models, and the importance of adapting our understanding of aesthetics. Interviews with Fiction Factory, Circu-leren, Hollandse Nieuwe, NICE, Fokkema & Partners, Superuse Studios, LBP|SIGHT, and Opera amongst others. Contributions by David van Nunen, Jaapjan Berg, Material Cultures, Ruth Baumeister, Simon J. Barker, Remy Heijer, Jingshi Liu, Aylin Cakanlar, Gergaa Nenkov, Pascal Leboucq, ROTOR, and Stephan Petermann.
