The entire project includes three main spaces, 2 internal gardens and 1 robotic 3D printed pavilion. The 40m x 80m column-free garden space is covered with digital steel & wood vault, which is the most economical inter-supported steel-wood roof in the world. In the center of the venue, the 3D Robotic Printed Pavilion utilizes recycled plastic and is further optimized through a topology-optimization algorithm and 3D printing techniques. Assisted with the advanced construction technology, the entire project was realized within 100 days.
