The Oceanic Pavilion designed by Emergent Architecture and Kokkugia for the Yeosu 2012 Expo in Korea is a structure “which celebrates the ocean as a living organism and the co-existence of human culture and ocean ecosystems. The building is based on an aggregation of soft membrane bubbles merged together with a hard monocoque shell. The two systems are characterized by patterns of surface articulation which are specific to their materiality”. Deep pleats and mega-armatures that create structural stiffness are generally associated with the fiber-composite shell, while fine, double-pleated ‘Air-beams‘spread over and stabilize the vaulted ETFE membranes. Micro-armatures transgress thresholds between shell and membrane, creating structural and ornamental continuity between systems.
