Thank you all so much for the info so far. This is really fantastic. You guys are giving me a good head start.
So it sounds like 40" or so oven is about the right size. I'll definitely do a bit more reading on this.
I'll check into the local codes as well, but I don't imagine it to be a real problem building it close to the house considering there is a natural gas outlet coming out of the wall for a grill right where I'd like to place the oven. I'm guessing here, but grills can't be anymore dangerous than WFOs. Heck maybe I'm wrong.
I'm attaching some photos of the area that I think would work well for the WFO to be. It's basically my front covered patio right outside the kitchen. The area from the column to the wall and sliding door is about 7'x7'. I'm hoping to place an oven and a bit of counter space there. Maybe enough for that Primo grill as well (somewhere).
Regardless of the official codes, it is important to make sure the opening of your oven is not exposed to the wind - you know the kind of diabolic gusts common around here, especially in the spring and summer. You don't want to be the guy whose pizza oven burned down the Bosque. I'd make sure it is oriented and has wind breaks so that, no matter which direction the wind blows, there is no way embers will be blown out of the oven.
Bill that is excellent advice. I hadn't even considered that but you are right. Luckily I have a somewhat enclosed front patio surround by walls and an iron rod gate. The area that I would like the WFO to go is somewhat enclosed as well on 3 sides, so I hope that I'm good to go. The entrance of the WFO would be facing east, there's a big sliding glass door towards the north, the back wall is towards the west, and the south would be open. let me know what you think.
Marc and David. Thank you for suggesting the Steffano Ferrar"i" oven. Even though I can afford a 10K oven, it probably isn't the one for me. I have 2 little girls that will have to go to college someday and my wife and I do enjoy the occassional get away.
If it's the creme de la creme, I feel I would have no business getting one. I could/would not be able to fully appreciate it. I hardly even know how to make a NP yet. Maybe if I was opening a pizzeria or if I had trained under some prominent masters, then there would be no question about it. I just wouldn't be able to do the oven justice IMO. It is out of my league?
I am considering getting plans and building one like member Ev for the experience but finding the time might be tricky. My front yard would be a mess for a while and I'm not sure my wife would go for that either. I told her that I wanted a WFO a couple of days ago and that it would cost about $3500. I was just throwing a number out there to see the expression on her face. She didn't seem surprise and said, well if it'll make you happy then go for it.
So I think I could push that number up a bit if needed.
I'd like to put the oven right where that primo ceramic oven is. I can always have a slab poured next to that area for the WFO and then it wouldn't be covered anymore. From that colum towards the wall and sliding glass door is about 7 feet both ways. The ceiling again is about 10 feet high. The oven floor would be about 40" high maybe, then another 30" or so for the oven. That leaves around 4 feet for the chimney. Would I need to hire someone to extend the chimney through that ceiling? I'm guessing so...
