Has anyone used Barn Guru (or others) for blueprints?

As the title says, has anyone bought and used blueprints from Barn Guru to build a barn? We are considering purchasing plans and the framing guide to build a barn ourself. How easy were the plans to work from and were you able to do minor modifications (i.e. door/window placement) without much or any trouble?

Any other blueprint company recommendations? Pros, cons, general observations are much appreciate. Thanks!

I have never even seen their website before.

I do wonder some things…
Looking at just a few of their floor plans, to me they have made some really silly design choices (unless they are building those apartments in only warm climates for example).

Do they ask for soil testing or anything before they issue you “footing layout and footing details”?

I looked around a little, are the drawings stamped for a professional in your state? Or do you have to turn around and do that for your permit?
