 This is the company Nuaholz and it's a similar system and the idea is to have many layers of wood in different directions, vertical, horizontal, diagonal and then this is pressed together and it's connected with wood sticks that are hyperdried and then they are hammered in and then they take up the surrounding moisture and they make it very very very strong without any chemicals so it's that's why wood 100 because it's only wood. Now remember my first slide we had this demolition phase if you have such a house the demolition is not demolition it's like harvesting high price materials because the wood is even better than when it started because it's very dry wood it's massive wood so it can be reused for another building can be used for making furniture and so on so it's and if everything else fails it can still be used for for firewood or for energy production
