Eco-design studio Biobased Creations has built a show home almost entirely from biomaterials including wood, mycelium, seaweed, straw and vegetable fibers as well as earth and sewage. Unveiled at Dutch Design Week, the house showcases 100 different plant-based or natural materials that are commercially available already or coming to market soon. The only non-bio materials are metal screw fixings and glass windows. "We used 100 bio-based materials because we wanted to show what is possible," says Biobased Creations CEO and co-founder Lucas De Man. Their aim is to show how eco-materials can be used in building ordinary homes." If we want to build a million houses here in Holland in the next 10 years, then the design has to be scalable," said De Man.
