In this post and in following posts we'll see an earth oven being constructed in Maine by a couple who took one of my oven building workshops. Looks like the kids are helping out.
Excavation finished. Don't underestimate the amount of work this takes
Gravel added for good drainage
Concrete slab poured
Beginning flat stone base, and flat stones are the easiest stones to lay up.
Stay tuned for the next phase which should happen in a couple of weeks.
