Nice to see that the typical begrudgery in this country is still alive and well!
It's not begrudgery, it's about making sure we're comparing apples with apples.
And you're also confusing my comment on spec, with workmanship. There is no connection between the two. If you build a basic specification (and I have no issue with that), you should still expect top workmanship. In many cases, a lower spec, finished well, is better than a higher spec, finished poorly.
I am glad that you are happy with what you got - that is the idea, after all. And neither am I against non-Irish builders - half our crew is non-Irish, and they work very well. Again, Sconhome is trying to determine whether the costs of running a business are reflected in the price you paid, or whether it's a 'cash job'. Being 'registered' tells us neither.
And, I understand you don't care. But if someone decides to do whatever-you-do-for-a-living for cash, and takes your job/put you out of business, then I can guarantee you that you will. And you should extend that courtesy to those of us that do.
All that said, if you everything is, truly, perfect, and legit etc etc, and say the guy did it just to have something to do, rather than be idle (at/below cost), and the price you paid reflects that - you have done well, no question about it.
