This research explores the intersection of Extended Reality (XR) and architectural fabrication, specifically through the innovative application of XR technology in the construction of a pavilion using natural materials, namely twigs. Recognizing the limitations of traditional architectural tools in facilitating intuitive interaction and natural engagement, this project leverages XR as a powerful medium to enhance the fabrication process. The workflow devised for this study was systematically divided into two core phases: initial data collection and subsequent form generation. By integrating immersive digital environments with hands-on fabrication techniques, the research aims to demonstrate how XR can significantly augment creative exploration and practical execution in architectural design and construction.
