Having decided to make a pizza oven there are a few things you need.
Solid base to build on.   It ends up very  heavy!
I used concrete blocks and then made a steel frame and poured a concrete pad on top.
In the middle area where the base of the oven will be I a poured a concrete/vermiculite base about 30mm thick to act as insulation for the stone.

next step is to create the chamber

Step 1: The Chamber

The all important chamber stores the heat and focus's the heat from the fire onto the floor where the cooking will happen.

For this I used Blue engineering bricks, type A are the only ones good for this sort of heat, you don't need firebricks (they cost lots)
I used about 200 bricks, got them for about £60 off ebay

the mortar needs to be high temp, so a mix using terracotta clay sand and cement was used, it goes off but gets harder when fired.
as you can see i created a form using hardboard and ply. I bought the clay from a kiln/pottery suppliers. It needs to be high temp firing.

As you can see from the second 2 photos I have created the chamber then used regular bricks backed by firebricks to make the opening on the front, I used a form for this brickwork as well.

There is a special dimension for the opening, The height of the opening needs to be no more then about 70% of the height of the chamber otherwise smoke comes out and it needs to be wide enough to allow good access.

<p>Thanks for the feedback guys, so over a year of use now and we have it down to a slick operation, we have some SSteel staging as a prep table and roll out the dough and then let the guests put thier own toppings on, good fun with about 6-16 people. I have installed twinwall flue andthat works great, only issue is the wearing of the oven bas stone, this was 25mm turkish linestone, and although tough it has started to de-lam in places due to the heat. I will be looking for Granite counter top off cuts to replace it at some point. other than that its a great asset.</p>
<p>nicest looking wfo that I have seen. It has given me inspiration to make ours in a similar style, so thanks for posting</p>
What an awesome build! What &quot;tool&quot; are you using to slide the pizza in and out, it looks pretty big?
I bought a 12&quot; pizza peel , there are photos of it in the last pages, the original one was just thrown together to test the oven prior to it arriving, you also need a hook and something to shove things about and a brush on a stick is very useful but it needs to be natural bristle not plastic as you use it to clean the oven floor between pizzas or after moving the ask about, even then it singes a little.
