The arches give a clean wide open space. Note that there is no plan bracing in the roof - profiled steel sheets were used to provide stability via diaphragm action.
The end gables were clad in light weight ETFE cushions
Spacing the footings at 12m centres along the building, with arches at 6m centres, reduced dig volume, concrete and reinforcement fabrication.
The wishbone legs supporting the main arches provided stability in the longitudinal axis as well as an interesting architectural feature.
To make the arch design as efficient as possible we derived the specific catenary formula that would fit around the intended internal zones. This allowed us to use a 323.9 CHS tube at 6m centres to span around 22 metres. This is a neat illustration of the concept of parametric design - albeit with a felt tip and a calculator in place of grasshopper and rhino.
