摘要

We present a case study on the design and fabrication of a timber cabin in Norway, featuring a free-form interior that transitions from vertical columns into an undulating ceiling surface. To ensure a tight alignment between wood fiber direction and the curved geometry, naturally formed tree roots are used for the columns. The tree roots are irregular in size and form, necessitating the development and deployment of a flexible robotic production workflow. A custom system is implemented, combining 3d scanning and multi-axis machining to analyze and adapt processing to each unique timber element. This allows real-time assessment of the workpiece form and corresponding adjustment of production geometry and parameters. It demonstrates how adaptive robotic fabrication can expand the range of usable timber forms in industrial production. By deploying adaptive digital workflows with non-standard timber forms, the project reveals new opportunities for material efficiency, agility, and expressive potential in timber architecture.
