The first and crucial step of building an outdoor fire pit is selecting the right place and preparing the place for building a structure. Choose a place that is even or at least nearly even. Also, make sure there are no trees or branches around and over the place. 

Remove all the obstacles, if any. Clean the place thoroughly. The diameter of the area should be at least 5 feet. Start to dig the ground with a spade. Dig at least 5 to 6-inch deep. Level the ground with the help of a shovel. 

Step 2: Marking Different Section

Now measure the diameter and mark the middle point. Place rebar on the point and tie the string with it. This string will help you to mark out different sections accurately. Firstly mark out the outer corner. Then mark liner for fire brick. And then mark the main fire area that should be 2-inch inside from the fire brick line. With spray paint, mark the inner section. 

Step 3: Pouring the Base
