I added a removable back wall that is actually done in two pieces. The back sunburst gable is glued in place, but the lower wall
slides out as needed. The exterior color is Warm White by Americana. It has interior trim to match the side walls, so it looks
seamless when viewed from inside. There's a jewelry finding nailed to the side as a knob. There are channels built for the wall to slide in and out, but they blend well when the wall is removed.
