The Shell Star Pavilion, designed with MATSYS by Andrew Kudless, Riyad Joucka and Ricci Wong, sheltered participants during the Detour 2012 festival.
The pavilion’s star shape refers both to the nearby sea and to the five-petal flower of the Bauhinia × blakeana orchid tree, the emblem on Hong Kong’s flag.
It was a temporary structure, built for the two-week festival. The pavilion was designed with digital modeling, simulation and fabrication tools.
Following the shell structures of Antoni Gaudí, Frei Otto and Félix Candela, the pavilion was designed as a thin shell working in compression, so that it could cover its 111 sqm.
Form-finding: mass is applied to each mesh node, each mesh edge becomes a spring, and the physical interactions are simulated until the system comes to rest.
