Well, I don't know what kind of craftsmen some people have here or how handy the builders are (I wouldn't exactly call myself clumsy), but I would say that I haven't managed any trade as well as the respective craftsmen so far... the only thing is I definitely wouldn't have put a roof tile on the roof, because it has a color defect in one spot... but you can only see that up close, so in the end it doesn't bother me either.
