The Guangzhou Garden, RHS Chelsea 2021
For Grant Associates Guangzhou Garden, we designed, engineered, fabricated and installed five filigree towers, ranging from 1.8 to 8.4 metres tall.
We worked from the early design stages to set the geometry and structure, and used MOSO N-finity laminated bamboo for its strength and durability outdoors.
Each tower uses gridshell principles: curved uprights wrapped in a lattice of spiralling strips, hand-bent into place.
We tested how far the bamboo strips could bend and twist, then moving between workshop experiments, full-scale prototypes and digital simulation until the geometry was right.
The largest tower needed its own rotating assembly frame, so the strips could be wound onto a temporary armature until the structure was stiff enough to stand on its own.
The garden won a Gold medal and Best in Show. Afterwards it was gifted to Bristol, Guangzhou’s sister city, and rebuilt at the University of Bristol Botanic Garden, where it officially opened on 1 May 2024.
