Green School Stockholm is a modern school concept by architecture studio 3XN. It aims to create an environment in which students can learn valuable lessons in sustainable living. The building itself is adjoined by two grand pivoting arcs. As each floor ascends the structure gradually twists to maximise sunlight exposure for the greenhouses contained within. Green walls and vertical farming systems also fill the space giving students the opportunity to learn from its environment, which, by its very nature, promotes environmental and ecological awareness.
