I’m sure it’s all possible if money was not an issue.

Is there any good way to retrofit from in ground post to stem wall or something similar. Also, I’m in a cold climate and wonder if a proper footing would help with heating. I’m worried about future resell and longevity of the post.

I just ordered steel for interior ceiling and trying to figure out if I should add a vapor barrier to bottom of truss first. Currently building a 30x40x14 building and have the walls and roof house wrapped with Kelly Clark Block It.
