From Coarse to Fine: Investigating root growth for architecture

Abstract This paper proposes plant root systems as biological role models and active biomaterials for innovative architectural design. Focusing on both coarse and fine root systems, the research combines biomimetic analysis, material-driven design, and experimental biodesign methods to explore how root growth principles can inform structural, anchoring, and connective systems. A temporary biolab enabled cultivation experiments, including root entanglement in granular media, hydroponic connectivity studies, embedded growth in 3D-printed soil structures, and the fabrication of patterned root mats. In parallel, digital modelling and analysis of scanned root systems supported the development of simulation workflows and speculative design applications. The project follows a radical exploration methodology integrating biological research, computational tools, and hands-on experimentation. Preliminary insights suggest roots’ capacity to stabilise substrates, connect inert components, and generate adaptive material systems. The findings establish a foundation for scalable, bio-integrated, and bio-inspired construction strategies and contribute to sustainable, resilient, and ecologically responsive practices.
