If you want a backyard privacy screen that looks custom but is honestly very doable in a weekend, this cinder block and lattice build is one of my favorite kinds of projects. It uses simple materials, creates a sturdy divider without a lot of complicated measuring, and gives you that clean, modern-meets-garden look that makes a patio feel so much more finished.
I love projects like this because they deliver a big visual payoff without requiring fancy carpentry skills. If you’re comfortable lifting blocks, checking level, and making a few straight cuts, you can absolutely make this. It’s especially great for anyone who wants more privacy around a seating area, hot tub, grill zone, or property edge without committing to a full fence.
Materials
12 large grey cinder blocks, standard 8 in. x 8 in. x 16 in.
Instructions
1. Choose and mark the exact location for your screen, keeping the run as straight as possible and allowing at least 16 inches of depth for the cinder block base.
2. Dig a shallow trench about 4 inches deep and slightly wider than the cinder blocks, then tamp the soil firm so the base will not shift later.
3. If you want extra weed control, lay landscape fabric in the trench, then add 2 inches of paver base and 1 inch of pea gravel, raking and tamping each layer until flat and level.
4. Dry-fit the first row of 6 cinder blocks in a straight line with the openings facing upward, checking every block with a level and adjusting underneath with gravel as needed.
5. Stack the second row of 6 cinder blocks directly on top of the first row so the openings remain aligned vertically, then secure each top block with landscape block adhesive before setting it in place.
6. Measure the full height of the block openings and trim the lattice panels if needed so they slide in with a snug fit but without forcing the wood.
7. Screw one pressure-treated wood strip to each vertical side of the lattice panels to create slightly thicker edges that sit firmly inside the cinder block channels.
8. Brush or wipe on a fresh coat of medium brown exterior stain if the lattice color is uneven, then let it dry fully before sealing with a clear exterior topcoat.
9. Slide each brown lattice panel down into the aligned cinder block openings, one panel at a time, keeping the lattice centered and upright as you work.
10. Add composite shims inside the block openings anywhere the lattice feels loose, tucking them low and out of sight so the panels stay straight without wobbling.
11. Step back and check the screen from both ends, making small adjustments so the tops align evenly and the lattice pattern looks straight across the full run.
12. For a cleaner finished look, run a small bead of exterior caulk in any obvious gaps where the wood insert meets the block, then let everything cure according to the product directions.
Variations & Tips
For more privacy: Use tighter-pattern lattice or attach outdoor reed screening or faux greenery to the back side of the lattice so you keep the same structure but get denser coverage.
For a longer screen: Repeat the same block-and-panel section in modules instead of trying to build one extra-long run all at once; it’s easier to keep each section level and straight.
For windy yards: Sink the base trench a little deeper and widen it, then use additional block adhesive and extra gravel compaction so the screen feels heavier and more anchored.
For a more polished look: I like to place matching planters in front of the cinder blocks with ornamental grass or trailing flowers, which softens the concrete and makes the whole screen look intentional.
Color option: If brown lattice doesn’t match your space, stain it a deeper walnut or paint it a soft black; just be sure the finish is rated for exterior use.
My best practical tip: Don’t skip the leveling stage. In my experience, these simple backyard builds look expensive when the lines are straight, and they look homemade fast when the base is even a little off.
