Biomimicry :
The Arc employs one of nature’s greatest strategies for creating large spaces with minimal structure. Within a human ribcage, a series of ribs working in compression are held in place by a tensioned flexible layer of muscle and skin. This creates a thin but strong encasement for the lungs. In the case of The Arc, arches working in compression are held in place by tensioned anticlastic gridshells. These fields of gridshells appear to drape across the spaces between impossibly thin arches soaring overhead, giving a whimsy, intimacy and beauty to the space. Although, the gridshells appear to hang from the arches, they actually hold them up.
criss-crossing parabolic arcs while fields of gridshell surfaces stitch the arches together. An illusion occurs where the roof appears to drape between the arches weighing them down, but the curving surface actually brings strength to the form. “The two systems together create an unique and highly efficient structure, able to flex under load allowing the weight to redistribute, easing localised forces on the arches.” -Neil Thomas @atelier.one Structural Engineer of The Arc at Green School Bali @greenschoolbali , designed by IBUKU @ibukubali , built by Bamboo Pure, concept by Jörg Stamm @jorg.stamm
The Arc structure works like the ribs of a mammal's chest, stabilized by tensile membranes analogous to tendons and muscles between ribs. Biologically, these highly tensile microscopic tendons transfer forces from bone to bone. In The Arc, bamboo splits transfer forces from arch to arch." -Jorg Stamm, Design Conceptor⠀⠀
The concepted structure for The Arc is totally unprecedented. Embarking on a design never before executed required some bravery and optimism. We were creative and stubborn enough to research and develop the answers needed for the success of the project

The Arc at Green School Bali enters a new era for organic architecture, with its 19 meter span arches, interconnected by anticlastic gridshells. It is a new community wellness space and gymnasium for the extraordinary campus, in collaboration with Jorg Stamm and Atelier One.
