How to Build A DIY Elevated Planter Box With Plans

Welcome today I will be showing you how to make this raised planter box out of redwood or cedar. There are downloadable plans in the description of this video.

The first step is to cut 6 of the fence boards. They are 72″ long, but fence boards aren’t always consistent, so I cut them to 71″.

After that, I measured the width of two boards together. For me it was 15″, but this may change based on your fence boards. With the remaining boards, I cut 4 pieces into 15″ lengths, to use for the ends of the planter box.

I ripped a 2×4 on the table saw to make a 2×2, then cut it into 4 15″ lengths for corner blocks. I layed out all the pieces on the ground, and screwed the side pieces to the corner blocks.

Then I stood up the sides and screwed the end pieces to the corner blocks. I ripped a fence board into 1″ strips on the table saw, and then screwed them to the inside of the box at the bottom.

These cleats will support the bottom of the planter box. With the 2 fence boards being used for the bottom, I cut out the corners, to accommodate the corner block.

Then I placed them inside the box, and finish nailed them to the support cleats all the way around. I cut some more 2x2s out of a 2×4, and screwed them together into a frame that fits inside the center of the box.

This frame will prevent the sides from bowing outward, and the bottom from bowing downward. I screwed the side boards to the central frame, as well as the bottom boards.

After that cut the fence boards into 3 32″ lengths on the miter saw. This required 1-1/2 fence boards. Then ripped 4 pieces at 2″ wide, and 4 pieces at 1-3/4″ wide.

I finish nailed the narrower strips into the corner blocks on the ends of the box, then nailed the wider strips up against them on the adjacent sides.

These get nailed into the corner block and also into the adjacent leg piece. I cut some more 2x2s to the length of the leg overhang, and then nailed them into the leg pieces as support blocks.

I also toe-nailed the support blocks to the planter box, for some more rigidity. Then cut some fence boards to 2-1/4″ wide, and mitered them together on the top of the box. I finish nailed this moulding into the fence boards comprising the sides of the box.

There should be a small overhang on this moulding. Then add 2-inch strips on the sides to cover up the screws. Next drill several 3/8″ holes near the bottom of the side boards, and 3/4″ holes on the bottom boards to allow drainage.

As you can see the project turned out really well. It was just a one day project, but now I have all this space to grow vegetables for myself and family.

And I don’t have to bend down while gardening, which is a huge plus for me. I hope you enjoyed it.
