Instructables

Step 2: Construction

 I built these boxes onsite as they get heavy quickly once assembled.  They are a simple box with a leg secured at each corner with lag bolts.

I cut the pressure treated lumber to size for the sides.
  • 10 - 2x12x4
  • 2 - 2x12x3
Then I cut the pressure treated posts
  • 12 - 4x4x3
Assembly consisted of screwing the sides together with the Galvanized screws to form a simple box.

Next attach the legs at each corner with the lag bolts.

Now use the 1/4 inch screen to cover the bottom of the box by screwing the screen to the lower sides of the box.  You may need to attach a middle board across the center of the box at the bottom if your screen is not wide enough to cover from side to side (mine was not).  This is where you use the Lath Screws - I used #8 x 1 - 1/4.

On top of the of the screen, place the landscape fabric down.  This will retain the soil that you are about to place on top.

Last step (prior to planting) is to add the soil and compost to your new garden.
