Step 1
Select a level location with excellent drainage to install the tarp shed. Draw two lines on the ground with spray paint. the lines should be 9 feet long, and parallel to each other with 4 feet between them.
Step 2
Use a post hole digger to dig a hole that is 2 1/2-feet deep at both ends of one line. Dig two more holes on the line 3 feet from each hole. Repeat on the other line. You should have a total of eight post-holes, four on each side.
Step 3
Shovel a 1/2-inch layer of gravel into the bottom of each hole using a shovel. This will help with drainage. Place a post upright in each hole. Pack dirt around the post tightly to hold it in place. Using the back of your shovel, firmly tamp it down.
Step 4
Carefully bend a wire grid panel and place each end inside the first two posts on each line. The panel should form an archway across both rows of posts. Use fencing staples to staple the ends of the panel to the tops of the first two posts on each row. Repeat to install the remaining two wire panels on the back and middle of the rows of posts.
Step 5
Place one sheet of plywood across the insides of all of the posts on one side. Screw the plywood to the posts with 2-inch wood screws. This forms a wall on the inside of the shed. Repeat on the other side.
Step 6
Place the heavy duty tarp over the wire panels. Adjust it to overhang evenly on all sides. Attach the tarp to the wire panels by attaching a cable tie to each grommet then attaching the cable tie to the wire panel.
