I constructed two different types of raised beds for growing vegetables, herbs and flowers a few years back. One was out of the Ikea shelving unit Hejne …
Dimensions: 78cm x 50cm x 171cm
I had this at home already and only had to modify the way it was built to turn it into a planter.
Construct the shelving unit by shifting 2 of the 4 long posts so that they sit just outside the frame of the shelving unit and not flush with the edge as shown in the picture. (This will give you more room at the top side of the planter for plants.)
Arrange the shelves so that they line the outside of the frame like the top shelf shown in the first picture above. You will need 6 shelf pieces:
Two on each long side of the planter with a gap in the middle, which we’ll address in the next step, and one on each short side.
The set only comes with 4 shelves so you will need to buy the expansion pack which adds an additional 2 shelves…
You won’t be needing the metal brace pieces that come with the shelf set, so set those aside. You will need two additional pieces of cut wood the same width as your gaps (or wider is also ok) cut to 47 cm long.
You can use two cut pieces of an old pallet, which is what I used, or other scrap wood planks that are cut to 47 cm long. Nail them to the inside of the frame to fill in the gaps between the two shelves on the long sides of the planter.
You should now have a raised bed that looks something like this…
This planter was very easy to construct as the shelves are already assembled when you buy the kit and just need to be faced outward along the edge of the frame to form a top and bottomless rectangular planting frame. Normally if you buy a raised bed for plants at a garden store they can run hundreds of dollars each. This planter cost me:
