Choose a flat area with at least 8 feet of clearance around it. Mark a circle 4 feet wide for the main pit and another smaller circle (2 feet wide) slightly overlapping it for the grill section.
Dig 4 inches deep in both circles and fill the base with gravel for stability and drainage. Tamp the surface until firm.
Begin stacking the larger circle first. Place the first ring of blocks snugly, then add two more layers, staggering the joints for strength.
Build the smaller side pit in the same way, connecting it slightly to the main pit so heat can flow through.
Insert the steel fire ring inside the main pit and place your grill grates securely on top of both openings.
Test the setup by lighting a small fire and adjusting the cooking grates’ height as needed for heat control.
