There are many things I love to know - as if I'm going to do in my small space, but this gives me a lot of delight and some base ideas. But I may not leave things like that. There is a chance of adapting the methods in my own way and on a smaller scale. I also loved the use of old wood at the bottom which will rot over time and sink to make way for more space to add growing medium on top. In our part, any wood on the ground/earth is devoured by the termites. In our old house even some windows are attacked by it. They had gone up 22 feet to reach the roof to get at the reapers! So we cannot use wood like you use there. So much wood you have used is fantastic fuel to boil water!
Thanks Dave for counting the bricks for me. Got a good idea of the number required. Helpful for calculations, just in case. I saw the Trish video also. I just thought it would have been more catchy had it been in the morning or evening sun.
