The new Taiyuan Botanical Garden Domes complex in Taiyuan, China features 3 domes ranging from 43m to 88m in diameter and from 12m to 30m in height. The largest of the three domes is the longest clear-span timber gridshell (non-triangulated) in the world. All three parabolic gridshells comprise light doubly curved glulam beams, arranged in two or three crossing layers.

Through the cooperation of all team members on three different continents in less than a year, a unique series of long-span timber structures was delivered to the city of Taiyuan, providing a beautiful, world-class attraction that emphasizes both sustainability and structural integrity.
