Exactly what I was thinking. ThanksCost has gotta be similar to stick framed, unless they're SIP. Still have to frame between the poles....windows, doors, wiring, plumbing, etc.
I wouldn't call those "pole buildings." It appears they are "barns" with "house" finishes. So you can't really just use a basic square foot method from a cost source unless you do some gymnastics to separate interior barn finishes from the residential finishes. Which may not be that difficult to do with M&S or similar.
