The increasing environmental pressure of the construction industry calls for new ways of thinking about how materials are sourced, used, and reintegrated into design processes. In this context, bio-based materials and circular strategies have gained growing attention, while advances in digital design and fabrication have begun to reshape architectural practice. However, these domains have largely evolved in parallel, and their combined implications for architectural design remain insufficiently explored. This study addresses this gap by examining their intersection through a bibliometric and thematic analysis of 1,375 publications indexed in the Web of Science Core Collection between 2006 and 2025. The analysis traces publication trends, collaboration patterns, and evolving thematic clusters, revealing a marked increase in research activity after 2020 and a growing convergence around additive manufacturing, biocomposites, and circular design approaches. To complement these findings, a focused content analysis of architecture-oriented studies is conducted, allowing a closer reading of how these developments are reflected in design practice. The results point to a shift from performance-driven material research toward approaches in which material behaviour, fabrication logic, and lifecycle considerations actively inform design decisions. Building on this, the study proposes the concept of a Digital Biocircular Design Paradigm, understood as an emerging condition in which digital processes, material systems, and circular strategies are integrated into architectural design. By linking large-scale mapping with architectural interpretation, the study contributes to ongoing discussions on material-oriented and sustainable design, offering a clearer framework for understanding how digital technologies and circular thinking jointly shape contemporary architectural practice.
