The ICD/ITKE Research Pavilion 2014-15 explores a novel construction method inspired by the underwater nest of the water spider. Using a robotic process, carbon fibers are applied inside an inflatable ETFE membrane to create a lightweight, material-efficient shell. Guided by computational design and agent-based simulations, fibers are placed only where needed, minimizing waste. A custom robotic tool integrates real-time sensor feedback for adaptive fabrication. This process enables a self-supporting, functionally integrated structure that combines formwork and envelope. Spanning 7.5 meters and weighing just 260kg, the pavilion showcases the architectural potential of biologically informed, cyber-physical design and fabrication systems.
