In the great variation of life there are wooden doors. The Wills pagoda also has an under width doorway. I opened it up to 16mm (original drawings show 4'4"). The doors on most are wiggly tin, but I was quite taken with the wood doors on the Llangollen Railway example - vertical boarding and chunky framing. so I thought these would be nice. 8 mil wide 25 mil tall, all 20 thou. Note the pencil marks to make sure I get the diagonals right.
