Your Welcome, Kyle: Glad it's helpful.
BTW: welcome to the forum. Enjoy the planning stag. I found it as much fun as building. Don't hesitate to ask any questions as you're going thru the various posts.

Also, in looking at my floor plan of what I did and cooking with it, the only thing I would do different is that my oven landing between the 2 arches where I show a 15" dimension, I would have liked it 1-2" shorter. If it was 2" shorter, and with my tall and angled flu-box transition above it, it still would have drawn air/smoke really well and people with shorter arms could access more of the oven.

Also, as you can see by my drawing 4-1/2 by 5 concrete cmu (Concrete Masonry Unit, 16" block) could be smaller if you did an igloo type dome and not need extra few inches for framing the 'house' over it. I also like the ovens others build with the concrete base at an angle (45deg) for slightly smaller footprint.

So many great ideas on this forum. Too bad we usually can build only 1 .

-Dino

Those are great suggestions! I really like the smaller footprint idea. The less concrete to mix the better for my back!
It is so hard to decide on a design there are so many creative possibilities.

thanks so much i came upon your post just in time i start the base next week and having seen your plans for spliting the storage has made me rethink ,i want two openings so the wood can be loaded at the back and have time to dry as some of the wood will no doubt be a little wet and can be unloaded at the front a lot dryer kind of rotating your wood stock thanks again

Hi
Another newbie here - and what a great site - today I finished the hearth slab. Iused a 4.5" vermiculite cement mix 5'x5' approx on top of a 4" concrete slab, but I surrounded it by 6" of concrete (about 12" at the front) so that I would not be building on the vermiculite which has a kind of spongy feel and seems a bit fragile. The (36") oven will of course rest on the vermiculite
No stand since my garden is sloped which means no convenient wood storage, and also the oven floor will be a little lower than I would have preferred. I have tried posting on other threads but for some reason my posts are vanishing into thin air so this is somewhat of a test. I will post a photo later if this works

Going back to hearth design, if concrete layer is purely for support could it be replaced with concrete lintels, which have pre-stressed steel reinforcement topped by Hardibacker board. I think gaps of a foot between lintels would still be OK to support modular oven. Not everyone wants to be mixing 3-4" of concrete. Any thoughts anyone??

It's all about the open span (distance between beams). You'd have to know the maximum load you can place on the backer board across the open span. My gut says you could probably get away with it in a modular design because you're working with larger pieces that will spread the load over larger areas. I wouldn't trust the design for a point load, though.

Thanks - I think it would work - open span for my base is 1.1 metres so I reckon 4 lintels would only leave spans of 5-6" of Hardibacker (sorry to mix metric & imperial!). If it doesn't look to be enough I could always double up the Hardibacker and epoxy the boards together to make a constrained layer for strength. Planning to use a modular oven so probably less weight than a brick Pompeii.

Question Re: Hearth Design Philosophy

In speaking with a local hardscape builder who has built many ovens he has recommended that I put splits on the cooking surface. if the cooking surface gets damaged or worn out I can then easily replace them. it seems plausible, what do you all think? How do you actually replace bricks inside the oven ten years later? that would seem impossible to do.

I would put more lintels in to reduce the gaps and it should work.
