Hi all, I live in Western Pennsylvania and I have been using a DIY backyard pizza oven for about 4 years which has fueled the desire to build a bigger better one. My first one was a great learning project and has a small opening and cooking area. Our friends and neighbors have all loved our pizza parties and I have served up to 30 pizzas in an afternoon in it. But I have a stronger desire for options like more space, longer heat retention and using it from inside our house in the winter and outside the house in the summer. I have been inspired to design and build one with an entrance in the wall of our house and an entrance from the back deck area. I found support for this idea on this forum which apparently turned out well for Mr. Allen.

I have done several calculations and sketches and felt like I needed to 3D model it to get a good idea of if it should work. I will post a bunch of pictures from the model as well as the following video showing the angles of the model with various pieces removed. This is a Pompeii oven with a 42 inch floor, 24 inch interior height to the dome, and 16 inch high by 23 inch wide entrances. I plan to have heavy steel doors to put in each opening which will be insulated on the interior. I know there will be heat loss in the entrances but I believe I will end up keeping the interior one closed off during the summer and vice versa during the winter. But it would also be nice to be able to start the fires mostly from the outside entrance to keep down the level of smoke and dirt in the house.

Following the Pompeii oven plans that have been so graciously shared along with so many great posts, I will pour 4-5 inch thick base next to the house on top of gravel covered in plastic. The dimensions will be 80 x 80 inches for the base with 5 layers of cinderblock and a 4 inch slab on top. Then I will add the Perlite or Vermiculite layer with my Firebrick floor set into it. I realize that there are certain details that I will have to figure out such as properly designing the entrance to the house and the materials that will be used to protect the house as well the finished look of the overall exterior. The model does not show the mortar on the dome but I am guessing you can visualize it. I want to have 1 chimney which would sit on top of a finished dome plus a layer of insulation. The chimney openings inside of both entrances would feed up to the main chimney on top. The chimney will have to be fairly tall to be higher than my 2nd story roof. I plan to frame the oven with metal studs and concrete board as you can see in the model and then fill with loose perlite or vermiculite. I may not have designed this correctly but the model turned out how I had it in my head. I believe I am going to have to buy 277 Firebricks (or more with the + 10% guide). Thankfully I found a local business that has them in ready supply so I don't plan to buy them all at once.
My wife is on board with the idea but wants me to at least hire a consultant to go over my plans and assess putting this against the house. I am thankful that it is winter and I have to stew over my plans for a while before I can start anything. If anyone has any thoughts or input then I would be grateful! If I am able to go ahead with this then I will post progress pictures and plan to record videos along the way in case someone else wants to make one like it. I appreciate the collaboration and sharing of knowledge that has gotten me this far.

). You would be wise to plan a vent to feed the fire's combustion needs without pulling all your house's warm or cool air into the oven & out the chimney system. Also, you'll want to make that incoming vent something that can be screened off to keep unwanted critters from exploring and something that can be blocked effectively when the oven is not in use. Don't forget that you will have an occasional cinder or coal pop out onto your kitchen floor...
