Building a house from a distance. New construction 300 km away.

You must not be a millimeter man. Question from Sir Fliese whether he should always do the offset at 50% or 66%, that is, how the tiles overlap, or even without overlap... Answer, what would you do if it were your house. He would take the 66% plus silver gray in the grout. We said, do it that way. We had clarified this by phone, as he was just on vacation when the question came. Or question, how the plaster should be painted. You could make a film about it or just tell him, take white, that's fine. Etc. pp

You must not be a millimeter man.

That's exactly what I was thinking too. There are many ways to lay tiles, install lamps, sockets... If you are not on site, you must not complain afterwards. You also don't have to complain just because you "imagined" this or that differently. That is the point: what was not communicated follows the thinking, mood or taste of the executing craftsman (not the general contractor). That may certainly sometimes be good and better than one thought oneself, but you must not be disappointed afterwards. You looked at the selected tiles nicely "in conjunction" on the Internet and Pinterest and get a different pattern - not incorrectly laid, not incorrectly executed, and not incorrectly communicated.

Basically, it should work with today's media possibilities. An expert is understood here, of course.

Stop bothering me with experts, site managers, all that nonsense! They take a bunch of money and the performance is often poor.

As I said, you'd better take a retiree who does this as a hobby and maybe has already built a few houses. He can be on site much more often and will also see more than the trained expert who comes once a month for the acceptance.

Problem: Finding such a retiree

Yes, but you cannot expect active communication from the craftsman ... most receive the plan from the boss and do it. They only talk when a trade crosses their area. Otherwise, not.

If we can do that with over 500 kilometers distance, you can easily do it

I understand that even without explicit pessimism with a question mark: 300 km versus 500 km distance are practically the same (spontaneous on-site appointments are impossible to handle in a slightly extended lunch break in both cases), whereas you bring 58 years of life experience to the table, but the OP only 25 – so I dare to claim that one cannot significantly pull off a "counteraction" to a crosswind on blind flight from the wrist as easily.

stop.
I just see you have network.
Are you moving to another, unfamiliar office or do you already know some people there?
Then include the colleagues.
