There is a growing interest in transitioning to a circular economy as an alternative to linear approach. In this context, there has been a renewed interest in materials such as timber, which is part of a natural renewable cycle with lower embodied energy compared to conventional construction. Academics and practitioners are investigating methods to implement Design for Circularity strategies with the objective of extending the service life of building materials, thereby reducing the necessity for virgin material extraction and the environmental impact of construction. The circulation of structural timber is crucial for making the most effective and long-term use of timber. This article discusses prerequisites for the circulation of structural timber, considering aspects of architectural and structural design. The fundamental concepts discussed are combined with findings from a comprehensive literature review focusing on the circulation of structural timber. The objective of this article is to identify possibilities, challenges, and critical knowledge gaps, with the aim of creating new knowledge that contributes to an increased and facilitated circulation of structural timber.
