Hadn't really got that far Tom.

Would need to be light enough to move in there so, probably treated 2x2 &/or 4s & treated ply exterior, possible tin roof.

Blue foam insulation & sealed by that cheap thin finishing sheeting.

2 shooting windows & 1 door.

1 issue I just thought of, is that it needs to be light enough to move into the back 40, but not so light as to blow over.

Basically, I have no idea !!
