桑德虫是在比利时文杜宁海岸线的沙丘上实现的有机结构 "生物"。 45米长，10米宽， 安装在建筑和环境艺术之间自由移动，完全由柳树构成，随着当地对工作与环境之间的互动的了解。 Casagrande与他的年轻建筑师和当地专家团队努力工作了4个星期，以创造一个他所描述的“薄弱建筑” - 人造结构，希望通过灵活性和有机存在成为自然的一部分。访客将桑orm are描述为一个柳树大教堂，精心设计，以庆祝文杜宁潮滩的具体情况。该空间用于野餐，放松和后工业冥想。 “在sandw sandw之内，你受到光影影响的自然景观的迎接。我惊叹了。如何用如此简单的天然材料创造这样的美。艺术家认为建筑控制与自然相违背，从而再次体现建筑。建立的人类环境是人与自然本身之间的调停者。要成为这个的一部分，人必须是软弱的。对芬兰艺术家Marco Casagrande的设计是不够的。设计不应取代现实。建筑物必须长出地点，它必须对其环境做出反应，它必须是生活的反映，也可以像其他生活一样自己。“ - 彼得·贝恩设计是不够的。设计不应取代现实。建筑物必须长出地点;它必须对其环境做出反应，它必须是生活的反映，也是其他生活的本身。建筑控制与自然相反，因此也反对建筑。建立的人类环境是人与自然本身之间的调停者。要成为这个的一部分，人必须是软弱的。
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 following the local knowledge of a continuing interaction between work and environment. 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. The visitors are describing the Sandworm as a willow cathedral finely tuned to celebrate the site specific conditions of the Wenduine tidal beaches. The space is used for picnics, relaxation and post industrial meditation. “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 artist believes that architectural control goes against nature and thus also agains architecture. The built human environment is a mediator between human nature and nature itself. To be part of this, man must be weak. To the Finnish artist Marco Casagrande designing is not sufficient. Design should not replace reality. The building must grow out of the location, it must react to its environment, it must be a reflection of life and also be itself, as every other living being.”- Peter BeyenDesigning is not sufficient.
