According to our idea, the walls should me made out mostly of poo but should be able to survive moving the wall as whole. It needs a frame. We build small scale model of the walls frame, that we would fill up with cow dung mixture.
Here we used mix of cow dung with saw dust (5:2) and water. And tried to compress it as much as possible.
If it ever dries out we will notify you about results 😀
