Floor plan of a single-family house, feedback

In principle, it is the question of how much entrepreneurial attitude you bring to your own construction project. There is no "right" or "wrong" but much more "appropriate" or "inappropriate" according to the building owner's personality.

Oh, entrepreneurial attitude towards the home project: if I haven’t forgotten anyone, then besides you I actually only know this from and .

that I awarded the contracts myself (not a generally advisable approach) and paid attention to the fact that carpenters and electricians already knew each other from various projects and were coordinated with each other. For the carpenters I purchased a trade coordination. Their site manager proved to be extremely competent and was significantly cheaper than a site management service according to HOAI.
It is a path with risks that can be seen and evaluated.

Self-awarding is mainly dangerous only for novice homeowners, and in the way you described it is actually exemplary.

I do not understand exactly what you mean. Explain at which points the separation of warranty could be difficult when the electrical installation is placed in a pre-wall construction?

The OP doesn’t want, like you, an installation in an installation level manufactured on site after the setting date, but rather empty conduits in the prefabricated walls (which are therefore produced deviating from the standard process). Here an aqueduct system for penetrating moisture (or even dampness) can easily develop.

The question comes to me like out of nowhere. What are you getting at?

At the total thickness of the interior walls with installation layers added on both sides. Two times three cm plus quickly come together there. A non-load-bearing interior wall approaches the thickness usual for load-bearing interior walls, and a load-bearing one even develops into a veritable cavernous man.

The OP does not want an installation like you, into an installation level fabricated on site after the installation date, but empty conduits in the prefabricated walls (which are produced deviating from the standard process for this purpose). Here, an aqueduct system can easily form for ingressing moisture (or even dampness).

The only thing that deviates is that I deliver the plan, not their standard electrician. It is an absolutely normal process that they do the pull wires and drill the boxes.

The OP does not want, like you, an installation in an installation level fabricated after the setting date, but empty conduits in the prefabricated walls (which are produced differently from the standard process for this purpose). This can easily create an aqueduct system for infiltrated moisture (or even dampness).

That is of course a difference. If the electrical planning is integrated into the migration position, then I agree with you. That carries a whole bunch of risks that even I would avoid.

The only thing that is different is that I deliver the plan,

I can only advise you against commissioning the company to build the empty conduits according to your plan. The smallest error – no matter by whom – has a big impact there. If a wall-to-wall connection simply doesn't fit – then you have a huge problem and immediately lose claims if you start drilling. The factory people will not want to start drilling either. Result: In the best case a few weeks of construction delay. In the worst case no satisfactory solution. You get a house that does not come from a series production, but from a finely standardized manufacturing process that is highly sensitive to changes. The intervention by an empty conduit plan not coming from this process is significant.

On the total thickness of the interior walls with installation levels added on both sides.

We do not have any interior walls that were manufactured in the factory if you do not count the load-bearing partition walls between the three residential units as classic interior walls. In general, we hardly have any interior walls. The few meters around the bathrooms and the guest toilet, as well as the beverage refrigerator, we had constructed on site using drywall construction.

I can only advise you against hiring the company to install the empty conduits according to your plan. The smallest mistakes - no matter by whom - have a big impact. If just one wall-to-wall connection doesn’t fit, you immediately have a huge problem and lose any claims as soon as you start drilling. Even the people from the factory won’t want to start drilling. Result: In the best case, a few weeks of construction delay. In the worst case, no satisfactory solution.
You are getting a house that, although not from mass production, comes from a finely segmented standardized production process that is highly sensitive to changes. The intervention by an electrical plan that does not come from this process is significant.

I don’t understand that part.

My walls will be assembled the same way as always. Boxes and cables will be installed just like always. There’s nothing different except that the plan "box X here, Y there" was written not by person A, but by person B.

The walls are delivered finished (both sides closed, holes for boxes made, pull wire going up). The ceilings are open. They assemble the house on site. Then the electrician (no matter if mine or theirs) runs the cables, following the pull wire up into the ceiling sections and from there to the destination. Then they come back and close the ceilings and finish their work.

Where am I supposed to drill, for what? Where is there more risk in that? I don’t want them to do things that require completely reconfiguring their machines and everything experimental, with processes no one has ever seen before.

I don't understand that part.

No problem. It's simply about the difference between theory and practice. Since there is theoretically none, a discussion about it is difficult.

My walls are assembled the same way as always. Boxes and cables go in just like always.

And therein lies the risk, because that applies to the craftsmanship aspect, but neither to work preparation (especially machine setup), nor to quality control (aspects that usually never have to be considered). Therefore, it may be that the walls are indeed "assembled" exactly as you somewhat disparagingly put it, as usual, go through quality control as usual, are installed as usual, and then it turns out, for example, that a transition from wall to wall is unfortunately slightly misaligned and the cable ducts do not connect to each other.

And therein lies the risk, because that applies to the craft aspect, but neither to work preparation (especially machine setup), nor to quality control (aspects that otherwise never have to be considered). Therefore, it may be that the walls are "cobbled together" exactly as you somewhat disparagingly put it as usual, go through quality control just as usual, are installed just as usual, and then it turns out that, for example, a transition from wall to wall is unfortunately slightly offset and the cable ducts do not connect to each other.

But that can just as easily happen if their electrician makes the plan. I see no difference there either.
