Strong and watertight, the material is permeated by a soft, changing light which creates intriguing iridescent effects. The rainbow reflections thus created are ideally suited to the architects’ aesthetics. This large pavilion, composed of flexible and organic shapes, is in harmony with environment, the architects defending the idea that “nature must prevail over architecture”. Inflatable seats installed in the structure, attached by straps, will allow visitors to sit, lean, or stretch out in the context of workshops, concerts, presentations, conferences, markets, games, moments of relaxation, wanderings, etc.
