I was sorting through my Steck stuff setting aside bits I'm wanting to get rid of when I was diverted to the stuff I was keeping and came up with the custom in the photo. It needs the end wall open frame filled in with plastic sheet and I'll put some brown painted strips on it to represent the wood frame. The other end which you can't see is two of the small open frames joined with a stone double connector; these will be filled in to. I reckoned at that end, as it takes some of the weight of the roof on the single storey section, the use of stone and smaller wood and plaster sections made sound building sense.
