Cob building has been around for thousands of years and been used around the world. It may be one of the most ancient technologies yet it is still one of the best.
What makes it so amazing is that it is able to be made for free, is super strong, super insulating and the materials are abundantly available around the world.
I have more videos to post about using this and will post videos on how to make a cob rocket stove which is also very useful and sustainable yet much more manageable than making a house.
