I have been doing research on better building materials and came across the idea about building structures out of sandbags and the soil/dirt you have available to you.
Very similar to earth rammed houses, you basically fill up a sand bag / tube with moist earth and pack it down, it creates something harder than concrete when it dries if you use the right mixture of dirt and clay. There is a good youtube series of a (quirky) family making these structures. Instead of buying a huge house they make a little cabin for each of the kids. I am honestly wondering why this isn’t more popular…
What do you folks think?
Better insulation / protection
