Step 6: Completing the Foundation:

Picture of Completing the Foundation:

I stagger stacked five more layers of building block.  After each layer of block, I filled the square with “urbanite” and large rock, filled all of the spaces and covered the rubble with 5/8” minus, and compacted it all with a length of 4”x4”.  I did not fill the last layer of block so that the insulation layer would be deep enough.  I capped the last layer of cmu with the 4”X8”x16” concrete cap.

is it possible to design it to have a wood storage area under the oven? That would be convenient if it could be done.

Did you lay the blocks set in mortar or did you just dry lay them without any mortar or other adhesive?
