This mixed-reality overlay is a form of craftsmanship with precise digital references, utilizing holographic lines to define adjustable bending positions and verify part shapes during assembly. While preserving skilled handwork, it explores the concept of craftsmanship within a Thai context. Steam-bent rattan pieces are shaped and assembled to create a spatially curved network. This structure is supported by 3D-printed robotic concrete components that function as foundations, rims, and seats. This project combines established fabrication processes and materials with modern tools. Steam-bent rattan, commonly used in furniture, is applied at an architectural scale, reflecting local material culture alongside advanced technology to propose a future living solution for Bang Khun Thian.
