I’ve seen some pretty cool things done with them
Sturdy sheĺls and airtight
I’ve always thought this should be a good thing
Best one I’ve seen was two of them sitting side by side, 20 foot apart with a gable truss roof over them. Gave you storage on each side and a nice big roofed area in between.
I don’t see them as very good for living spaces. How much ceiling weight do you end up with after insulating? One isn’t wide enough to do much, especially after insulation and inner wall coverings so now you need to cut a side out of two of them and put the open sides against each other like a double wide mobile home and you’d have to put some columns in to support the middle. All while working with corrugated walls.
