The timber volume in Sweden and Japan are large. When forests grow the carbon dioxide sequester in trees. After harvesting, carbon dioxide stays in the wood until it either moulders or burns, and is then released back into the atmosphere. A sustainable forest secures a cycle that re-absorb carbon dioxide through the growth of new trees and protects biodiversity. The treasures of the forest is a source of sustainable development and the future of wood should enable an everyday use of it. How can a manmade commonplace – a koja/koya – show the potential of the treasures of the forest? How can these treasures of the forest become a new typology in an urban context, within the dense city centre?
