$100 Pizza Oven

$100-pizza-oven

I was hungry for pizza so I built a pizza oven, that makes sense right? As most of you might of gathered by now we like food an awful lot, especially baking and our, lets call it a “healthy” obsession takes up a good portion of our time. So when we heard the Melbourne Pizza Festival was coming to town we were sold on the idea. Mouth watering succulent pizza would be on offer and who are we to refuse, but sadly we only managed to get our mouths around just two slices and that just wasn’t quite enough to tame our wild stomachs. I’m not saying the festival or pizza wasn’t good, far from it, but unfortunetly for us they had failed to allow room for half of Melbourne to fit and so resulted in a very crowded venue, and a very hungry us. It was decided: we need a wood fired oven, but one that could be abandoned should the need arise due to our renting status, and it must be completed on a budget. Challenge accepted.

The basics of an oven are somewhat simple, heat – in this instance from a fire and thermal mass – bricks and render (clay would have been a better for thermal mass but I’m lazy so render will do). The fire heats the oven and the bricks store the energy to be released and used to cook your pizza, bread, roast, whatever your appetite calls for. This oven was built with this in mind but on a budget, here we go…

Materials and Cost breakdown

5 Pallets – Donated
18 Cement paving stones – Had
180’ish Bricks (old clinkers) – Had
Chicken wire (about 2sqm) – Had
Chimney if required  – Had
Sand – $60 for 2/3 meter 
Lime – $10
Cement -$15

Total $85

With the fifteen dollars we had spare I’m going to buy a bottle of wine and christen her this weekend, results to come!

Instructions – The boring bit

The pictures are pretty self explanatory, I started with a base (pallets donated by a local builder) and then built up. I wanted to use some cement sheeting for insulation over the pallets but with the budget in mind I laid some old cement paving stones insteed, tightly layering them on the pallets. Then I mortared (MIX 4-1-1) in a line of bricks around the edge of the base and filled the centre with tightly packed sand. The sand was then covered with bricks that were persuaded into place with a mallet, the base is tightly packed but not set with mortar as it’s the baking surface.

Then I started laying my bricks, around and around leaving some room for an entry at the front. Using an old length of steel from our garden, I formed a lintel and set a terracotta arch on the lintel and continued to taper the brick dome inwards. From here I created a platform inside the dome and covered it with sand shaping the inside of the dome and giving the bricks something to rest on while being laid and then setting in place.

I added a length of chimney from the front of the dome, held in place with chicken wire which also helps to strengthen the structure. After a day I carefully removed the platform and shaping sand and then set to work rendering the facade, this not only looks nice but increases the thermal mass. The render is about the same mix as the mortar but with a little more lime for flexibility. Over the bricks I have a render layer then a sheet of chicken wire to aid with strength and topped with a smooth render layer. At its thickest point the oven would be almost twenty centimetres.

What could I have done different?
Well if money wasn’t an object, almost everything, but this amaizingly cheap project took me about six hours in total and came in under budget. I call success, now who’s for a slice of pizza?

    • The trick with any timber resting on the ground is to coat it with tar paint (fence black), and then apply a decking oil or wax to the timber. It just depends on your local environment. But you are correct Bunny, They can and will rot if not treated properly.

  1. This is amazing! We’ve been wanting something like this for ages, but they are so expensive to buy … I have to show my dad this (ha ha – I’m not doing it!) and maybe we’ll be doing the pizza thing soon too 😉

  2. Pretty damn good pizza oven,
    i can barelly taste your passion my friend!
    unfortunately, i think build this kind of oven is impossible since i lived in a hectic area,
    i guess somebody gonna sue me right after i made the fire (actually the smoke )

  4. As I just posted about building a pizza oven that would cost around $900, I’m amazed at your creativity. Since I don’t yet own the property where I will build my future pizza oven, you just saved me a bundle!!

    • So cool, thank you! We haven’t yet, because I think it will wait until we are ‘entertaining’ so we don’t eat too many ourselves. With only two in our house, we need to be quite disciplined when making treats 🙂
