Sure, but this boils down to the 'You don't know what you don't know' situation.
Maybe, but you do know if you are looking for advice and engineering insight or not. If not, you have to assume that the priority was not that high. If you want a house built and feel that the design is important we all know that you high a trained architect. If not and you just want to be cheap, you just buy a book of blueprints and hope for the best. But we know what we don't know.
