Steps to Build a House Number Planter Box

You can download full build plans for this project on Exmark’s Backyard Life. Watch the video above to see how it’s done!

  1. Take the 1-in. x 5-¾-in. x 9-¼-in. front panel and one 1-in. x 5-¾-in. x 7-in. side panel and line them up so that they form a 90-degree angle. Pre-drill a hole through the front panel and secure the two pieces together with 2-inch. screws.
  2. Take the other side panel and repeat step 1 on the other end of the front panel, forming a U-shaped assembly.
  3. Lay the partial planter box build on its side, so that the U-shape is parallel with the ground.
  4. Take the 1-in. x 7-in. x 7-¾-in. bottom panel and slide it into the U-shaped assembly. Line it even with the edges of the front and side panels.
  5. Pre-drill holes through the front and side panels. Screw and secure the bottom panel to the rest of the assembly. You will now have a partial cube with an open side and top.
  6. Take the 1-in. x 9-¼-in. x 37-½-in. back panel and lay it across the planter box assembly. Line the panel up with the bottom and sides and flush along the remaining open side.
  7. Screw the backing piece to the address planter box. Drill a small hole in the middle of the bottom of the planter to allow for drainage.
  8. Apply the wood stain and water sealer to the house number planter.
  9. Take the cast iron numbers and attach them to your planter with screws, making sure they’re centered and evenly spaced. (Some numbers are sold with screws already. These are fine to use so long as they’re long enough to be properly secured to the backing board.)
