That is quite a build - Mine will allow me to do a porchetta - 6 loaves of bread or 5 pizza's at a time so this will be funBit hard to get size with frangipani tree overhanging. I used old reclaimed pre 1900 bricks for the outside same as my house.And matched the roof pitch & roof tile to house. Still had to deal with local authorities over the fact that I neglected to get aproval,but I fought the law & I won.Good luck with your build.
What you are looking at is only the base. There will be a big oven sitting on top of it - Here is what the inner shell looks like
I did a stack of research before I built mine including looking at home builds around me here.Yes people get carried away building them,me included,they get way over engineered .I reckon mine is earthquake proof.BUT THERE ARE TWO THINGS, use refractory cement & fire clay in your mortar & whatever you use over the outside of the bricks,cement render etc put heavy duty foil over it first.That way the expansion & different cooling rates wont tear the joints in your bricks.Once it tears thats it sand in your food,heat leakage crack gets bigger
