The Shell Star Pavilion is designed to provide an exciting shelter for participants during the Detour 2012 festival. The pavilion’s star shape references both the nearby sea and the 5-petal flower of the bauhinia blakeana orchid tree, the iconic symbol featured on Hong Kong’s flag. The design seeks to create an innovative, dynamic, and iconic temporary structure for use during the 2-week festival. The pavilion is designed using cutting edge digital modeling, simulation, and fabrication tools. Based on the concept of a purely compressive structure developed by architects and engineers such as Antonio Guadi, Frei Otto, and Felix Candela, the Shell Star Pavilion can be made from a minimum of thin material while covering a large area. The pavilion is the product of an emergent process that combines form, material, and performance into one integrated whole.
