Mark a rectangular area about 4 feet long and 2 feet wide. Then dig 3–4 inches deep and fill the base with sand or gravel for drainage.
Lay concrete pavers flat in the center to create a heat-resistant floor. Make sure they sit evenly.
Build the first layer of blocks around the perimeter, ensuring tight joints and a level foundation.
Stack two or three more layers, offsetting seams for better stability. You can secure them with fire-safe adhesive if desired.
Place the steel fire grate in the center for airflow and wood support. Add the removable grill grate at one end for cooking versatility.
Fill the small gaps outside with gravel or decorative stones for a neat finish.
