A privacy trellis is a multi-purpose structure used in many gardens and yards. Not only does it prevent neighbors and people on the street from peering in, but it also blocks winds and offers the opportunity to grow a lush green vertical wall, freeing up gardening space so you can plant other plants and vegetables. This functional yet decorative structure is relatively easy to build and does not require construction skills or prior experience.
How to Build a Privacy Trellis
Measure the length of the area to be trellised and determine the trellis height. It can be used to screen out a particular spot of your garden or an entire side. Ideally, a 6-foot high trellis provides sufficient privacy without making the area feel too enclosed.
Place seven 1-by-2s 2 inches apart on a level surface. Make sure all the tops and ends of the boards are level. Place another seven boards on top of but perpendicular to the previously placed boards, spaced 2 inches apart.
Mark each intersection with pen. Starting at one side of the structure, secure all intersecting pen marks together with the electric drill and galvanized wood screws.
Measure and mark 1 to 1 ½-inches downward from the top of the first vertical board and place a 2-by-4 horizontally over it. Drill this upper frame of 2-by-4 into place at each intersection with wood screws. Place another 2-by-4 against the edge where it falls short and continue drilling into place until your trellis has an upper frame. Use a saw to cut any protruding edge. Repeat the same procedure, placing the lower frame an inch above the end of the first vertical board, so your trellis has a lower frame.
Measure and cut two lengths of 2-by-4 for the vertical posts, at least 2 feet longer than the trellis length. The extra bit will go into the ground to hold the weight of the trellis. Place one of 2-by-4s vertically under the upper horizontal frame, and start drilling it into place at each intersection.
Repeat the procedure for the other vertical post.
Measure and mark the appropriate distance for the trellis posts on the ground with powdered chalk. Dig two 2-feet deep holes over the marks with a shovel or post-hole digger. Put a layer of gravel, at least 6 to 8 inches, into each hole to support the posts securely.
Carefully lower the trellis posts into the holes in the ground. Backfill soil around the posts and tamp it down to remove air pockets.
