A tree house that can't burn! The building of a public and a Christian school in Zaltbommel in the Netherlands looks like a cosy wooden structure. Yet the material is made of stone fibre and has the properties of stone: it does not rot, is sustainable, long-lasting and needs hardly any maintenance. Who wouldn't want to be a child there? Situated right next to a beautiful park, the building fits perfectly into the surrounding area – and not only the little residents love it.
