The Arc is a feat of engineering; it required months of research and development and fine tuning of many tailor-made details. The result is a very refined design with an immediate beauty, which stands as a testament to IBUKU’s commitment to expanding horizons in architecture and design.
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
“The gridshells use shape stiffness to form the roof enclosure and provide buckling resistance to the parabolic arches. The two systems together create an unique and highly efficient structure, able to flex under load allowing the structure to redistribute weight, easing localised forces on the arches,” explains Neil Thomas, Director of Atelier One.
