I know that we have featured a number of planter boxes in the past, but you can never have too many styles when building an item. I like to take a number of wood plans and take a piece from each to come up with my own piece. I might use a particular joinery technique from one plan and a design style from another.
The following planter box plan comes from DannyLipford.com and uses stock lumber from Home Depot or Lowe’s along with simple joinery techniques. This planter box requires a minimum amount of tools due to the stock material and simple joinery.
Good luck building your planter box plan. The PDF plan can be downloaded by clicking on the picture of the planter.
