A simple fire ring like this can completely change how a backyard feels. By stacking curved retaining wall blocks in a circle over a neat bed of pea gravel, you get a clean, sturdy spot for evening fires that looks polished enough to lift the whole yard.
I love projects like this because they’re approachable for a weekend, don’t require fancy carpentry skills, and make it so much easier to gather outside with family and friends. If you want a backyard feature that feels welcoming, practical, and surprisingly high-end, this is a wonderful place to start.
Materials
36 gray curved retaining wall blocks, 12 inches long x 4 inches high x 8 inches deep
Instructions
1. Choose a level spot in the yard with at least 10 to 20 feet of clearance from structures, fences, low branches, and anything flammable. Check local fire codes before you build so the size and placement meet your town’s rules.
2. Mark a 3-foot-radius circle for the gravel pad using string and a center stake or marking paint. This gives you a 6-foot-wide footprint that frames the fire ring nicely and keeps the area looking finished.
3. Remove the grass and soil inside the circle to a depth of about 4 to 5 inches. Try to keep the bottom as even as possible, because a level base makes the block ring much easier to stack neatly.
4. Lay the landscape fabric across the excavated circle and trim it to fit, leaving a little extra at the edges. This helps separate the gravel from the soil and slows weed growth over time.
5. Spread 2 inches of paver base or crushed gravel over the fabric, then rake it smooth and level. Compact it firmly so the base feels solid underfoot and doesn’t shift later.
6. Set the steel fire ring insert in the center of the pad, then arrange the first course of curved retaining wall blocks around it. Adjust the blocks until the circle looks even and the spacing around the insert is consistent.
7. Check the first course for level from block to block and make small adjustments by adding or removing a little base material underneath as needed. Take your time here, because every course above will follow this one.
8. Stack the second course of blocks on top, staggering the joints so each block bridges the seam below it. If you want extra stability, add a bead of landscape block adhesive between courses before setting each block.
9. Add a third course the same way, again staggering the joints for strength and a more polished look. Step back every few blocks to make sure the circle still looks balanced from all sides.
10. Fill the rest of the surrounding pad with tan pea gravel to a depth of 2 to 3 inches, covering the base area evenly up to the outer edge of the circle. Rake the gravel smooth so the fire ring looks tidy and intentional.
11. Walk around the ring and make any final adjustments to block alignment, gravel depth, and overall level. Once everything is snug and even, your fire ring is ready for use after any adhesive has cured according to the package directions.
Variations & Tips
For a larger gathering spot: Increase the gravel pad to 7 or 8 feet across so there’s more room around the fire ring for chairs and foot traffic.
For picky backyard stylists: If your family likes a more rustic look, choose tumbled blocks; if you prefer a crisp modern look, go with smoother-faced gray blocks.
For easier maintenance: Refresh the pea gravel once or twice a season with a quick rake. I do this before we have friends over, and it makes the whole area look cared for in just a few minutes.
For extra durability: A steel insert helps protect the blocks from direct heat and can extend the life of the fire ring, especially if you plan to use it often.
For better drainage: If your yard tends to stay wet after rain, add an extra inch of compacted base and build the pad just slightly proud of the surrounding lawn.
Safety tip: Only burn seasoned firewood, keep a bucket of water or hose nearby, and never leave the fire unattended. Around my house, that simple routine helps everyone relax and enjoy the evening a little more.
