You might want to try to bond your courses better, to avoid multi course running joints. Also, consider tightening up the brick work on top of the dome a bit more.  Otherwise, they look great, excellent finish work.  I especially like your chimney on the last picture, and how clean you built the squirrel tail flue and throat on the first oven.  Very professional looking.

I meant to ask....with the first oven, did you carry the flue up through the roof or does it vent out underneath the way it is shown?  I'm curious about the floor insulation as well.

the orange bricks under the floor are an insulating brick. its light and can be cut with a hand saw. i used to use the calcium silicante board but these are way better. Under the orange bricks i used Hebel as my slab.

i haven't finished with the flue yet, but need to install triple skin flue near the roof part so as to be permit approved

Thanks Stonecutter. I am not reallt happy with the top brick dome part. its fiddly and you need lots of precise cuts which take time. For the money these people pay i need to be quick. But your right.

Finished dome Height ? where do you get the insulating brick ? Who manufactures the Floor/Hearth  tiles and what is their composition ?
What was the total build time approx.
The Oven Looks great !! I would prefer that to any kit available in the USA for sure

Wow they all look very good. Great job.

Just a few comments. Not sure if got it right from the picture but it doesn't look like you use foil between the stucco and the insulation. You may want to use foil as it helps some insulating. Now days the ceramic fiber blanket will dissolve in water, over time, so being in direct contact with the stucco takes some of the insulation property away. Also the insulation will absorb some of the water in stucco, accelerates the drying and makes it weaker.
Finely I would suggest you use diamond mesh rather than chicken wire to support the stucco. It will make it a lot stronger.

Keep the picture coming.

I completely understand that sometimes speed has to come first...hope I dont come off as too critical. Reality is that it will function fine as long as the building basics are put to practice, and it doesn't look like that's a problem.

Btw,  I looked at you pizzas, they all look fantastic!

No i didn't use foil between render and insulation. i should of though.
I agree that when motor dries quickly it becomes weaker.
i normally use a tighter diamond mesh, smaller holes, but i didn't realise when i bought it , till i opened up the pack. 
But thank you for the advice. Will take it onboard

Here is the first oven finished with an acrylic texture and black board paint for the front arch. The owner wants to write on it .

Thanks.
That's where my trade comes into play . My dad taught me well.
I used a thin bendable mdf sheet cut into 100mm strip and used it as a straight edge to get the accurate curve.
It's easier than you think
