Building a barrel pizza oven is quite an experience and you will definitely enjoy it. To make the excessive fun, you need to first collect all the required materials and go through the barrel pizza oven building plans and procedures. In addition, understand what you want as to adjust the dimensions appropriately.
The process begins with laying the foundation, which can be made of clay, sand, or cement. After that, you need to raise the foundation to about 20” then set the oven.
