Build a Backyard Fire Pit in One Weekend

Stacked stone, no mortar, no concrete — a solid fire pit that becomes the center of every evening outside.

Build a Backyard Fire Pit in One Weekend

Materials

  • Concrete retaining wall blocks (~36 for 3 courses)
  • Paver base gravel (4–5 bags)
  • Sand (2 bags)
  • Steel fire ring insert (optional but recommended)
  • Lava rock for the base

Tools

  • Shovel
  • Tamper
  • Level
  • Rubber mallet
  • Wheelbarrow

How to build it

  1. 1

    Pick the spot

    Choose a location at least 10 feet from structures, fences, and overhanging branches. Check local fire codes first — some areas require permits or specific clearances.

  2. 2

    Excavate and level the base

    Mark a circle (drive a stake, tie a string, walk the circle with paint). Dig out 6" of soil, add 4" of paver base, and tamp it until it's firm and level. A solid base is 80% of a fire pit that doesn't lean by spring.

  3. 3

    Lay the first course

    Set the first ring of blocks on the base, checking level on every single block — side to side and front to back. Tap high spots down with the rubber mallet. The first course must be perfect; the rest follow it.

  4. 4

    Stack remaining courses

    Stagger the joints like brickwork. Set the steel ring inside before the final course if you're using one — it shields the blocks from direct flame and doubles the pit's lifespan.

  5. 5

    Fill and enjoy

    Add 2–3" of lava rock inside for drainage, surround the outside with gravel or pavers, and season the pit with a small first fire.

Pro tip

Buy 5–6 extra blocks. A few always arrive chipped, and matching blocks years later is nearly impossible.
