A freestanding wooden lattice screen adds privacy without attaching anything to the house, deck, or patio slab. This version uses two pressure-treated posts, a framed lattice panel, and a wide-footprint base that resists tipping. It is suitable for a weekend build with basic tools and can be sized to suit your patio.

Plan the screen before buying materials
A practical finished size is about 6 feet wide by 6 feet tall. That is large enough to block a seated neighbor’s view, but still manageable to assemble and move. Do not build a tall, narrow screen with a small base: solid wind pressure can overturn it even when the frame feels heavy.
Check local rules before starting. Some cities treat freestanding privacy screens like fences, especially near property lines. Also identify overhead wires, sprinklers, and buried utilities if you will dig footings rather than use surface-mounted bases.
| Design choice | Advantages | Trade-offs |
|---|---|---|
| Wood lattice | Easy to cut, paint, and repair; relatively inexpensive | Needs sealing and can rot at exposed end grain |
| Vinyl lattice | Does not need regular painting and will not rust | More prone to cracking during cutting and can look less substantial |
| Open lattice | Lets wind through and uses less material | Provides partial rather than complete privacy |
| Solid panel | Blocks more sightlines | Acts like a sail and needs a heavier, wider base |
For the simplest build, buy a 4-by-8-foot pressure-treated lattice panel and cut it to approximately 68 by 68 inches. Look for pressure-treated wood lattice panels with consistent spacing and no split corners. A cheaper thin lattice is fine in a sheltered location, but it tends to flex and crack when fastened tightly.
Materials and tools
You will need two 4-by-4-by-8-foot pressure-treated posts, four 2-by-4 boards for the lattice frame, two additional 2-by-4 boards for the feet or runners, exterior screws, galvanized or stainless lattice screws, exterior wood glue, and concrete or paver blocks depending on the base design.
Use exterior deck screws that are rated for treated lumber. Standard interior screws can corrode quickly, leaving black stains and weak connections. Gather a tape measure, square, pencil, drill-driver, countersink bit, circular saw, clamps, and a level. A miter saw is convenient but not necessary.
Wear eye protection when cutting lattice. Pressure-treated wood is dusty and splinter-prone, so use a dust mask and wash your hands before eating.
Build the lattice frame
Cut two 2-by-4s to 68 inches for the sides and two to 65 inches for the top and bottom. The shorter pieces fit between the side pieces, producing an outside frame roughly 68 by 68 inches. Lay the parts on a flat surface, check that each corner is square, and fasten each joint with two 2 1/2-inch exterior screws. Drill pilot holes near the board ends to reduce splitting.
Measure diagonally from corner to corner in both directions. The measurements should be within 1/8 inch. If they differ, push the longer diagonal inward until the frame is square, then add screws. A frame that is not square will make the lattice buckle or leave uneven gaps.
Cut the lattice approximately 1/4 inch smaller than the inside opening in both directions. This clearance allows seasonal movement and makes installation easier. Do not force a tight panel into the frame. Lay the lattice over the back, center it, and secure it with screws and washers every 8 to 12 inches around the perimeter. Predrill near the edges; lattice strips split easily.
For a finished appearance on both sides, add a second layer of lattice or install thin 1-by-2 trim over the screw heads. The second layer improves privacy only if its openings are offset, but it adds weight and wind resistance.
Attach the posts and build a stable base
Stand the frame between the two 4-by-4 posts, with the top of the frame about 4 inches below the post tops. Leave roughly 2 inches of post showing below the frame. Clamp everything together, check for level and equal spacing, and drive pairs of 3-inch exterior screws through the posts into the frame at each connection.
For a patio installation, make two feet from 2-by-4s or larger lumber. Cut each runner to 36 to 42 inches long and fasten one to the bottom of each post, perpendicular to the screen. Use at least four 3-inch screws per connection, staggered so they do not collide. Add triangular 2-by-4 braces from each post to its runner if the screen can be bumped or exposed to wind.
On a hard, level patio, set the runners on rubber pads or paver blocks to keep the wood off standing water. If the screen will sit on soil, use 4-by-4 post bases anchored to concrete or install the posts in concrete footings. Do not bury untreated cut ends directly in wet soil.
Finish, anchor, and maintain it
Before final assembly, brush preservative onto every cut end, especially the bottoms of the posts and the lattice edges. Apply two coats of an exterior stain or paint after the wood is dry enough to accept it. A penetrating stain is easier to touch up; paint gives better color coverage but can peel when moisture gets behind it.
Place the screen where you want it and check it from several angles. If it rocks, correct the patio contact points rather than tightening random screws. For a windy site, add two concealed sandbags over the runners or bolt the runners to concrete. A 6-foot screen with open lattice may survive ordinary breezes on its own, but it should not be trusted during severe weather.
Inspect the frame each spring and fall. Tighten loose screws, repaint exposed end grain, and look for soft wood around the bottom of the posts. Replace cracked lattice strips before they pull adjacent fasteners loose. If the screen is in full sun, expect the finish to need attention every two to three years; shaded, sheltered screens may go longer.
For seasonal storage, remove the sandbags or anchors, tip the screen onto its side with help, and keep it under cover with air circulation. Never wrap damp wood tightly in plastic, which traps moisture and accelerates rot.
