Tools and Materials:
framing nailer with air compressor and hoses
power miter saw
T-square and tape measure
four 8” strap hinges
17 sheets 4x8 privacy lattice
12 pieces of 2x4x12 pressure-treated lumber
25 pieces of 2x2x8 pressure-treated lumber
25 pieces of 4x4x8 pressure-treated lumber
1. Build the frame for enclosure. Nail 2x4s to existing posts to create the frame needed to secure the lattice panels. Start at the bottom of the frame keeping the wood 3 to 4 inches off the ground.
2. Run vertical 2x4s from the bottom plate to the existing deck. Each one will be a little different since you’re following the contour of the ground with the bottom plate. Continue nailing in vertical 2x4s, 48 inches on center. Make sure to place a 2x4 where each panel seam is located (every 4 inches).
3. Be sure to frame in an access door somewhere around the enclosure. Your local building codes probably require this.
4. To install the lattice, measure vertically from the top of the panel (the bottom of the deck) to the ground. Write it down. At the other end of the panel (4 feet away) take a measurement from the top of the panel to the ground. These two numbers will probably be different. Transfer these numbers to the lattice panel, and connect the dots using a T-square or chalk line. Cut the panel with a circular saw then nail it to the frame.
5. Build the door frame using pressure treated 2x4s. Measure the frame from one corner to the other and cut another 2x4 to that size then nail it in a vertical angle to support the frame (creating a Z pattern). For even further support, add two more diagonal 2x4s on each side of the big diagonal piece, about 2 to 3 feet away.
6. To give the lattice work a cleaner look and get rid of the rough edges and gaps, use pressure treated 1x4s to create a frame. Cut as many 1x4s as you did 2x4s. If you made a previous cut list you can just use the same measurements to save time and materials. Using a narrow-crown stapler to nail the 1x4s over the lattice seams.
7. Use outdoor gate hardware for the access panel. You can find it at home-supply stores and it usually comes in a kit with all the parts and instructions. It will also likely come with combination of bolts and screws, so make sure you have the proper bits for your screw gun. Fasten the hardware to a secure post that is holding up the deck so your access door will remain straight and won’t sag.
