How to Build a Box Planter on Casters with a Lattice

Measure then cut four square side panels for the planter: two should be 15 1/2-inches square and two 14 3/4-inches square.

Cut the planter bottom to measure 13 7/8-inches square.

Measure and cut four pieces of wood for the top edge, measuring 17 inches by 3/4-inch by 1-1/2 inches.

Cut four ledge pieces to hold the bottom onto the planter: two with a measurement of 14 inches by 3/4-inch by 3/4-inch and two pieces measuring 12-1/2 inches by 3/4-inch by 3/4-inch.

Assemble the side panels and apply wood glue along the edges to hold them in place. Attach the pieces together with two 1-inch long screws along each edge.

Glue the top trim pieces onto the top of the sides so there is no overlap on the inside edge. Nail three 1-inch long brad nails to secure each piece to the planter.

Affix the ledge piece with wood glue about 3/4-inch from the inside bottom edge of the planter. Secure the ledge by nailing three 1-inch long brad nails along each side.

Drill five 1/4-inch drainage holes evenly around the bottom planter piece. Slide the bottom piece into the planter so it rests on the bottom ledge.

Screw one caster wheel unit into each bottom corner of the planter.

Cut the lattice to a width of 14-1/2 inches and a height of 4 feet. Place the lattice on one inside panel of the planter and attach it with eight to 10 brad nails to hold it in place.
