Complex timber dome made of 713 unique beams completed in Shanghai

Summary

The Seed Pavilion in Shanghai's West Bund is a wooden dome composed of 713 uniquely twisted glulam beams, merging parametric design, CNC fabrication, and low-carbon strategies.

Why it matters

By showcasing the first double-curved twisted glulam structure, it pushes the boundaries of timber engineering and digital fabrication. The project references Xu Guangqi's agricultural legacy, aligning computational design with cultural heritage while aiming for zero-carbon construction and operation.

Highlights

• 713 individually designed timber elements (48 primary, 665 secondary) required unique geometry and fabrication data.
• Parametric modeling and BIM guided the CNC machining process, achieving an approximate tolerance of 0.14%.
• The pavilion utilizes glulam and transparent acrylic panels to maximize natural light, supporting its low-carbon objectives.

Critical take

While the design is technically impressive, its high degree of customization may limit scalability and increase costs compared to more modular timber solutions.
