Sandworm is an organic structure/space/creature realized on the dunes of the Wenduine coastline, Belgium. The 45 meters long and 10 m wide and high installation moves freely in-between architecture and environmental art and is constructed entirely out of willow.


Casagrande worked hard with his team of young architects and local experts for 4 weeks in order to create something that he describes as “weak architecture” – a human made structure that wishes to become part of nature through flexibility and organic presence.

Additional Information

Inside the sandworm you are greeted by a natural spectacle of light and shadow. I was amazed. How you can create such beauty with such simple natural materials.The built human environment is a mediator between human nature and nature itself. To be part of this, man must be weak. - Peter Beyen
