DIY Outdoor Pizza Oven for Under $150

2 Materials
2 Hours

We have a family text thread where my brothers love to talk about all things food. One day my younger brother posted this DIY Outdoor Pizza Oven idea, and I got hooked. Since then we have built two and molded different ideas into our favorite design. Here I share the step by step process of each layer, the cost break down, and our experience cooking with this DIY Outdoor Pizza Oven!

This simple outdoor oven will only cost around $150!

Materials List

  • (4) 16 inch x 16 inch Square Stone Concrete Pavers ~ $4.38 a piece
  • (18) 8 inch x 12 inch Concrete Olde Manor Wall Blocks ~ $2.78 a piece
  • (4) 12 inch x 12 inch Square Stone Concrete Pavers ~ $1.68 a piece
  • (47) Standard Paver Bricks ~ $.48 a piece
  • (6) 8 inch x 16 inch Paver Stones ~ $.98 a piece
  • (2) 1.5 inch x 48 inch, 1/4 inch thick Plain Steel Bar ~ $13.98 a piece (will cut in half)

Foundation Base

Your ground needs to be even and level so the pavers sit well. We laid 3/8 gravel rock, then flattened it out to make sure it was level. A 3 foot 2×4 helped us pat down the area.

You will start the foundation base by laying four 16 inch x 16 inch pavers. Use a level to make sure they are straight and even, and especially that they are secure.

Layer One

Next up is the foundation which is three layers of the 8 inch by 12 inch wall blocks (stone). You can honestly do as many layers of the stone that you would like, we just chose to do three layers. Place the first stones in the center of the foundation base and then add two onto each of the sides.

Layer Two

Add another layer of stone, turning the pieces this time.

Layer Three

Make one more layer, adding the stones in the same direction you added the first layer.

Oven Base

Here you place four 12 inch by 12 inch pavers to create your oven base. Make sure to space them apart about 3/4 inches to allow air to flow underneath the fire.

Oven Layer One

Place 7 bricks down onto the Oven Base, 3 in the back and 2 on each side. We reused brick we had previously cooked with hence why some have black edges already.

Oven Layer Two

Place 8 bricks down on top of the first layer, but having 2 in the back and 3 on each side. You may want to use bricks to hold the end pieces into place while waiting to get the 3rd layer on.

Oven Layer Three

Add 7 more bricks just like you did on the first layer, 3 in back and 2 on each side.

Oven Layer Four

Lay 8 bricks, just like the second layer, 2 in back and 3 on each side

Oven Top

Now you add the oven top. Grab your metal braces, 3 bricks and 3 of the 8 inch by 16 inch pavers. Place the first set of two metal braces that were cut in half onto the brick first, spaced about 8 inches apart.

Air Flow

Then add 3 bricks to the back of the oven. The middle brick will need to be pushed back about 1 inch to allow air flow.

Oven Top

Once that is finished you will add your 3 pavers to the top.

Top Layer One

Add another layer of bricks, 3 to the back and 2 on each side. Make sure the middle back brick is also moved back by one inch to help with air flow.

Top Layer Two

Add another layer of brick in the exact same way as you just did. They will be matching, except the middle back brick will now be even with the other bricks. You have created a small air tunnel.

Metal Braces

You are almost done! Now add the other 2 metal braces at 8 or so inches apart.

Final Layer

Finally add the last 8 inch by 16 inch pavers to create a top. We pushed them forward so they are not flush with the back. You can add 3 bricks here if you would like to as well.

    Don’t you need to use firebrick for the layers exposed to heat so they don’t crack? How does it hold heat with such a large non-domed opening?

      Yes I explain all of that on the blog post. You can also use clay brick. We found this out after we built it so all the information is on the post. Thank you!

    How is this thing heated? I don't see any place where the fire or any burner is hooked up.

    love it. Actually tweaked it to make it higher and ease of access for “us old  folk”

    • Yah!! This is brilliant!! I added a section in my blog about fire brick or clay brick. Not all the research agrees that some concrete can explode, so I added all those articles for you to reference as you would like. Thank you!
