The Kelp Rack Pavilion is an Australian pavilion that challenges unsustainable consumption habits and explores the dichotomy between rigidity and flexibility. It takes inspiration from a food preservation system, the drying rack, and uses wood and kelp as modular and circular bio-based materials. The pavilion is designed to be a meeting and exhibition space with a positive life cycle analysis outcome. It features a framework made of Jarrah timber and a malleable and fluid facade made of kelp. The pavilion’s design is easy to disassemble, allowing for better maintenance and the prospect of reusability and upcycling. The pavilion provides an immersive experience in nature and sustainable materials for students and visitors at UWA.
