Thanks guys.
I can check it out Edgar. I'll save my "favors" for real ones. I'd really rather not have to buy shipped wood. I can't imagine that being easy or practical but who knows. I'm surprised they import their wood.
I am pretty skilled with concrete and masonry and am sure I can make the Primo oven. Obviously I need to make it well for a very long life.
The patio is concrete with at least 4-5 inches solid and is not going anywhere so I don't have the foundation issue to worry about. I would do the corner version of the Primo surrounedd on both sides by 8 feet concrete walls. I'm going to see if I can't steal a couple inches anyway in the design without sacrificing quality.
Here we go.
