Stair Planter

What We Did

We got 1×6″ pine board for the sides and feet, and plywood for the bottom of the planter. We built four triangular segments – two larger ones for the first tier, and two smaller ones for the top tier. These segments were connected using metal brackets and wood glue.

Each segment is a right triangle (for a 90° corner) with two sides of equal length, and a longer diagonal. ​

After assembly, we painted the planter white and planted it with a mix of edibles and ornamentals.

For a detailed step-by-step guide see the assembly slideshow below.

  • 1×6 pine board. Make a sketch with side dimensions to find out how much you’ll need.
  • Plywood. A triangle cut from 1″ thick plywood will serve as the bottom of your planter.
  • 8-10 metal braces (tie plates). We got 1 13/16″x5″ tie plates.
  • Wood screws. 2″ long, and 1″ screws. You’ll want to make sure the 1″ screws fit through the holes in your tie plates.
  • Nails
  • Sandpaper. 100 grade.
  • Wood Glue
  • Outdoor Paint. We painted our planter white, but you can choose any color you like to complement your plants and outdoor setup.
