Cob is a mixture of clay, sand, and fiber. The fiber gives the walls tensile strength so if a crack does form the wall is still connected by the fiber making the patch easy and effective. For fiber we used a mix of sisal, coconut coir, and sticks.
I have a high recommendation for using sticks in every section as it gave the cob enough strength to get a good section of wall build every day as well as tie each layer together.
And what is a home without cute friends to share it with?!? Notice the windows. They are 5L water bottles filled with water and a cap full of bleach. I added some pipe glue when I screwed the caps back on. The best thing about them is when the sun shines directly through they cast rainbows across the room.
A home isn’t a home without plants. These plants are wonderful. How many people can eat their house? They also help cool the sweltering the air that passes through the windows. Making our house the coolest around!
