No, that is clear. If you come to the conclusion that this doesn't help someone like me with my attitude, that's also okay and does not cause any animosities on my part. For me, the task is actually to get the current draft (with adjustments) safely to the finish line with the already selected general contractor. That of course does not correspond to the modules you recommended on the journey to homeownership and therefore it is also perfectly fine if that does not meet your expectations of productive work with clients.
As you can see in the already published "Reloaded" episodes of the house construction schedule, it can also be varied by advanced users and is understood as a guideline, not as a binding "law". Accordingly, for productive work with advisees, it is not strictly necessary that they proceed according to "DIN 11ant" and I have no static expectations. Overall, the advisees must feel they have made progress to appreciate my consultation according to the intensity of my effort. Everyone has to come to the conviction of the value of the advice themselves; I cannot carry anyone there. And my impression here leads me to suspect that you might react in private consultations as you do here, namely as "Trudes Tier" would say: "where [I]come from, certainly."
But I actually wanted to know if my question regarding windows is better suited elsewhere, then I would gladly post it there where it belongs.
Primarily, I am interested in the content of the question.
Does having a splash guard around the house make sense with a ventilated facade?
No appealing dirt-repellent or even self-cleaning ventilated facade comes to my mind for such a thing.
