Materials

  • 16 standard cinder blocks (8 x 8 x 16 inches)
  • 6 bags of decorative gravel or slate chippings (40 lbs each)
  • 4 wooden boards for benches (6 ft long each)
  • 4 planter boxes (optional for decoration)
  • Landscape fabric, shovel, and level

Instructions

  • Mark out a square area about 6 x 6 feet in your backyard. Remove the grass and dig about 2–3 inches deep.
  • Lay down landscape fabric to prevent weeds, then fill the base evenly with gravel or slate chips.
  • Arrange cinder blocks in a square shape (two blocks per side) to form the fire pit. Stack a second layer on top for extra height and stability.
  • Check that each block is level and stable. You can fill the inner gaps with smaller stones to strengthen the structure.
  • Build simple wooden bench seating around the pit using treated wood and sturdy supports. Then add planter boxes for a soft touch of greenery.
