This is the pallet with box attached that we got from the local hardware company, big box store. They didn't want it and I thought it would make a planter that Julia could drive up to in her wheelchair.
I had some old Styrofoam from packing boxes that I put in to insulate the sides from the cold Minnesota winters.
After the insulation I lined the inside with old vinyl siding and aluminum taped the corners to keep the insulation dry. The bottom has drainage holes in it to let out excess water.
Then I vinyl sided the whole thing so it would look good I am using salvaged parts as much as possible.
