This paper introduces the conceptual design of sustainable timber structures using raw wood. It pre-sents a workflow for systematically generating Nexorades using a tiling method for multi-valence quad subdivided surfaces. The system is designed based on an integrated framework combining re-sources from local forestry, knowledge from geometry processing, joinery for raw wood, laser scan-ning and digital fabrication, and structural engineering. Particular focus is given to Cross joint geome-try and tool-path generation. Also, the global structural performance of the system is assessed. The results indicate that the proposed design methodology can offer an efficient and sustainable construc-tion technique. Furthermore, the methodology is reflected in a robotically fabricated prototype, demonstrating that the design framework can seamlessly integrate digital tools and construction.
