How to Build Your Own Fire Pit


Step 4: Stack Additional Layers

Picture of Stack Additional Layers
Use a brush to clean debris from the surface of the previous layer. Overlap the layers of stone, leaving three or four random gaps between stones in every course. The gaps allow the fire to draw air into itself. We dry-stacked the stone. They may get out of alignment, but realignment is easy. We learned something the hard way: Put gravel into the center of the fire pit after you've stacked a couple of courses. Then spread it evenly when you're finished. We shoveled the gravel into the pit after it was completed and found lifting the gravel that high was unnecessary work.

If using a steel ring, those gaps will not be adding any airflow, as the steel ring will then block it. You could prop the ring up a bit and leave gaps in the bottom course.
