We are by no means "religiously fixed," whereas wood is ruled out (bad personal experiences) and I simply have not yet received an objectively sound recommendation for ETICS.
On the subject of "objectively sound recommendation," I recently said
The most important thing I can tell you as a professional (I gladly count myself among the pros, but never among the "experts") is: Professionals only have—of course, competence-dependent individually—a more well-founded idea, but their opinions are never more objective than those of ordinary people.
which for your wall construction means so far that my reserve towards ETICS does not come out of nowhere, but it has not yet been conclusively judged by God at the Last Judgment (or by the Kronen Zeitung or whatever someone considers the highest authority).
But what exactly would be your recommendation?
My concrete recommendation, in the absence of obstructive religious preconceptions, is always to have the general contractor (or, in the case of a genuine architectural planning, the architect) propose a wall construction as part of an all-inclusive planning. They have the business of stacking stones into houses down to a fine art. For the private planner, this means to reserve approximately four decimeters of material thickness for exterior walls all around.
As I already wrote, there was also a parallel draft from an architect. But what are we supposed to do if we don't like it? Still build it because it is probably "better" planned? If we are convinced that the current draft is not good, then we will probably go to another architect again. Currently, that is not the case.
The presumption of expertise compared to a trained architect is often justified—as I will still deal with your just-shown example in post #114. With architects, I always recommend the following approach: first go to an independent architect and work through "Module A" (service phases 1 and 2 according to HOAI; I have not yet dealt with an Austrian equivalent). These are the basic evaluation and the preliminary design phase. After that, I generally recommend a phase of letting things rest, after which one decides whether to continue with this architect also for the design phase (service phase 3) or the entire "Module B," or to go to another architect. I do not recommend plowing through the entire architectural guild until the eureka draft. After this resting phase, my recommendation is first to decide whether the implementation should be with a "prefabricated house" provider (then only service phase 3 with the architect) or with site-built construction (then the architect does the whole Module B). Where you found my stone mantra is stated in "A House-Building Roadmap, also for you: the HOAI phase model!".
I almost always have to go somewhere under the slab/basement. I see no problem if it is done cleanly.
Cleverly, one does not cover the pipes with more than the exterior wall and runs the branch pipes on the shortest straight path (coming around the house "from the back in" practically always means creating a need for avoidable inspection openings along this path).
