Good info guys.. I have been lurking and stuff for years now im just going to take the first steps and finish when i can. Had I started after my first year of lurking, I would already be enjoying my oven
No fears. It will all work out. If you're hand with tools, you're golden. You can't do every step by yourself though. Some of these processes take two people to do without killing yourself. Believe me. I like to these things by myself, but I was greatful for my neighbor who helped me out a bunch along the way.
I will make sure I pay close attention to how my chimney will be in relation to any nearby trees. I don't have a problem whacking a tree out of my backyard because we can use the sun light. I've already measured and the oven will be more than 20 feet away from the house. My main concern will be how close the chimney will be in relation to the top & sides of my redwood arbor. This brick oven is going to be just outside of the arbor area so that would be my only real concern. I'll do some measuring prior to starting the project and I guess if I really had to I could extend the size of the chimney to the height needed to clear the arbor.
And I'm not complaining at all when I read how much dirt you guys had to move.
I'm going to make my form for my arbor foundation and brick oven foundation and have it poured all at once. The arbor will be a 16 x 16 ft slab with rebar around the sides ranging from 4 inches in the center to five inches at the sides. The brick oven area will be a solid six inches.
I have alot of work ahead of me. My goal is to get the foundations for both arbor & oven poured by the end of March and stain the concrete when it's dried properly. Early April will start the building of the redwood arbor. When the arbor is done I'll be putting in roughly 450 - 500 sq. ft of patio. Possibly flag or Colorado blue stone. That puts me at the end of April into May.
I'm hoping to start the brick oven project sometime in late summer or early Fall.
I have seen some amazing photos of the work you guys have done and I'll admit I'm quite the perfectionist. I'm really handy with tools, landscaping & carpentry but this looks like it's going to be a challenge. I'm really hoping I can recruit a friend the excellent mason & carpentry skills. Maybe one of those you help me with mine and help you with yours type of deals. I'd feel much more comfortable with someone with experience. Can't wait start this.
People seem to be split on checking on a permit. I did to be on the safe side but didn't want to know the answer. Luckily the building inspector considers this an "outdoor BBQ" so no need for a permit. I checked zoning as well and it's not even listed so I "technically" could put it in my front yard. The one thing you should "consider" is the chimney stack in relation to your house nearby buildings. I think it's 2 feet taller than any structure within 10 feet. Mine is about 12 feet away from my house but my chimney needs to go 2 feet higher than my pergola.
Re the Foundation - I agree the thicker the better. 2" is cheap insurance. Hey at least you didn't have to dig down 30+ inched due to the frost line like I and your northern builders did.
Insulation is a must. If you want a brick dome look, you can build one out of terra cotta tile on the outside of the insulation. Besides, the exterior of the dome has huge gaps between the bricks, and doesn't look like much anyway.
Building inspectors consider freestanding brick ovens to be backyard barbeques, and allow them without inspection in most cases. You should pay attention to common sense precautions: The top of your chimney should be two feet above any structure within ten feet.
Thanks for all the advice. I'm going to do exactly what the Pompeii 42' specs call for. I'm going to pour a concrete foundation that's 77' x 86'. That's what I have room for so that's what I'll go with.
I'm also going to pour it 6' thick to be on the safe side.
I love the dome look that shows the exposed brick work. Is it mandatory for it to be insulated in order to achieve the proper heat or can it be left at the stage where the dome bricks are showing.
Also, do I need permits or a fire inspector to come out to o.k. the space since it's my backyard I can go ahead and build this. I'm hoping I don't have to get permits because my only fear would be being told that the space is a little tight. Any thoughts? Thx.
As to the foundation an option would be have the outside 12" deeper to allow for the pour there to be 6", that's where the cement blocks for the stand will be as well as the weight. But doing it all 6" will only add another yard of cement, about $75 here for me.
I've made a 42" and it sits on a stand that's 5 cement blocks long by 4.5 blocks wide. the blocks are nominal 8x8x16 but basically about 15.5' long. Add 4" on each edge for exterior. Remember the hearth will be the same dimension as the stand (unless you do a cantilever front curve as Ken and I've done) and you will be standing on it for a month as you install the dome. Don't make it smaller than you have to.
That makes sense to me. I had no idea of the weight of a brick oven.
I'll just dig two inches deeper in the area where the brick oven foundation is going so the slab for the brick oven and slab for the arbor will be level.
I'll have a custom home builder working with me on this project and he's poured many a foundation so I think I'm in good hands.
But you'll see alot of me on this site as I get closer to starting the brick oven. It makes sense to knock out the slab now while I'm building the forms to pour the slab for the arbor. Once the arbor project is complete and my stone patios I can come back to the oven project and the slab will already be in place. Thx. Franco
Seems to me that if my arbor slab is going to be 4' thick and the brick oven slab is going to be 6' thick I'll have to dig the brick oven foundation deeper 2' deeper if I want them both level.
Exactly.
I don't get any frost where I am in California. Any chance I could get by with a four inch thick slab for the brick oven or do you see major problems?
My personal opinion: These ovens weigh close to 5000 lbs. I think that the extra 2" is pretty cheap insurance. Digging out an extra 2" on your foundation is easy. The cost of the extra 2" concrete is negligible considering the cost of the whole project.
We have some guys on the forum who are much more educated about concrete than I... I'm sure they'll join the discussion!
Glad to hear that for the most part I'm on track with choosing the Pompeii 42' brick oven. I just did some quick measuring outside and I'll have no problem with the 77' x 86' foundation. I'm totally a bigger is better type guy so I'm happy I'm going with the 42' plans.
If your recommending that my brick oven slab be six inches thick I think what I'll have to do is dig that area out a little more. My end goal is to have the arbor slab tie into the brick oven slab and both be level. Don't want one higher than the other. Seems to me that if my arbor slab is going to be 4' thick and the brick oven slab is going to be 6' thick I'll have to dig the brick oven foundation deeper 2' deeper if I want them both level.

My wife doesn't know the slab that's coming off of the arbor slab is for a brick oven. She thinks it's where I'm going to put the bbq. Well, it is in a way. She'll be happy in fall when I'm making her a brick oven pizza.
Do you know off hand what the minimum size slab I could get away with for building a Pompeii 42' would be? I know I have room for a good size slab, just not sure if I have enough room for a 77' x 86' slab.
Franco,
I have about 4" of slab hanging out under the edges of my block stand. Just enough to do stucco, brick, or stone and still look good.
I would assume this means 77' in width x 86' in length? Is that correct?
Yes. I attached the foundation plans I drew up and used. Very close to the dimensions you gave. I added some length because my oven won't be connected to our patio. The dimensions worked out perfectly for my 42". You can look at the pics in my Picasa Album (linked in my signature below).
Is the 42' size brick oven perfect for most needs? Anyone know how many pies can fit in there at once? What's the opening size on the 42' oven?
Most everyone here agrees that bigger is better... and 42" is plenty BIG. You'll be surprised at how roomy it is when it's done. 42" oven is perfect for a small family or a BIG party.
I want it set up so when people are sitting under the arbor they can actually see the fire burning inside the oven or at least feel like they are part of the process.
You and I are planning a nearly identical space. My arbor construction begins this summer .
Doesn't matter if my brick oven foundation is raised, does it?
That will look cool!
I was hoping to not have to pour two different thicknesses of concrete.
I'm going to vote for a 6" foundation under the oven. You can do the two thicknesses in one pour, just set up the forms for it. Your concrete guys have done it before (or we'll help you figure it out if you are doing the forms yourself).
Good luck, and be sure to start posting pictures when you break ground!
