I was allowed to take a little snap shot of this item and went from there. Some barn siding material I have stacked behind my shop should fit the bill, so that's what I used. One major thing I did different then what the reference house showed was how the front rear and ends went together. Instead of butting together I overlapped like a log cabin. By using the barn siding, this seemed to be better.
One other feature I did was hand carve the front door. Not should is a light that attaches to the back. This helps light up the inside.
