Floor plan of a single-family house, feedback

That can happen just the same if their electrician makes the plan. I don't see any difference there either.

The manufacturer's insurance then regulates it through their electrician, but a "subcontractor of the client (!) as vicarious agent of the contractor" would still be without legal precedent.

From their electrician, this is then regulated by the manufacturer's insurance, but a "subcontractor of the client (!) as an agent of the contractor" will legally still be without precedent.

If the company accepts the contract in such a way that TE can plan the electrical work instead of their own electrician (which will be stipulated in writing), they will also have to take responsibility if something goes wrong.

If the company accepts the order so that TE can plan the electrical work instead of their own electrician (which will be agreed upon in writing), they will also have to take responsibility if something goes wrong.

So I see it like this:
If I deliver faulty planning and they carry it out according to my plans – then that is my problem and I have to figure out how to solve it.

If I deliver something and they carry it out incorrectly (all/some holes drilled wrong or something) – then that is their problem and they have to figure out how to solve it.

If the electrician I hired messes up, then that is my problem (which I may have contractually arranged with him beforehand).

And later warranty (during the time it applies) – if a component is broken that comes from them and is their responsibility – then that is their problem. If it is my responsibility then it is mine (or my electrician’s, again a contractual issue with him).

And yes, I am old enough, I know that sometimes issues can arise between two components in detail. Then both sides just have to be flexible and look for a solution that is acceptable for all parties when that happens.

All good. It is just a risk assessment, where one can come to different conclusions for good reasons. Of course, it can also work.

An electrician is also planning here and not a builder who actually has no idea.

Regarding the earthworks you still had, see above, I’ll inquire at the beginning of the week. Yes, they are around 110cm.

An offer came back today. Of course with positions that ultimately depend on what actually happens on site, as with the foundation, but now I know a target figure. It’s a gross 12k€. That means together with the foundation I have costs just under 50k€. A basement will probably cost significantly more. (But out of curiosity, I asked the foundation/sockel wall builder for a rough estimate of the difference. They also do basements, so it should give me a guideline without too much wasted effort.)
(With the adjusted plans here afterwards, it will be closer to 14k€, or so I estimate, since the garage protrudes further and therefore needs more substructure.)

Apart from that, there were new plans. I’ve already made a few comments, curious to see what you come up with.

The ground floor. The conservatory has come to 4.50x1.25m. They don’t offer a fully glazed one, hence the possibility of flat roof windows as drawn in, if I insist on that. But they advise against it, shading and costs argue against it. We don’t like that either.
If the conservatory is not to our liking, I can also have a bay window there, which would be cheaper—but also considerably less window area. That obviously contradicts the desire for lots of light, which is why the conservatory is drawn in first.

What strikes me initially are the (in my opinion) large wall sections that jut in there. I assume they are required for the statics, but it’s a point I will ask about, whether it can be done differently (or if different would immediately entail bay windows). Naively, I would hope a large steel beam above would suffice. What do you think about them?

The guest room currently has a far too small window planned, only 72 cm high. Same height as in the kitchen—yay, symmetry. But I don’t care about that much; there should be a 125 cm one in to have enough light in the room. The one in the kitchen is only that small so we can get a proper sink underneath.
The laundry chute drawn there is their suggestion—we had one planned but hadn’t included it in our wishes. It would come out there. Since that doesn’t make much sense, it is still there as a note, but a new proposal is already drawn to the left in the utility room. However, it has disadvantages in the upper floor, as the space for it then hangs into the children's room. In terms of size, it’s okay, but the corner makes it practically impossible to plan a bed or a closet properly there. So we will probably leave it out completely. A nice feature, but not essential. Laundry bags in the bathrooms, and then carry them to the machines...

The utility/technical room is now nicely large and has a door planned to the outside. Although here I would still like to swap the arrangement of the washing machine/dryer and the washbasin. The door to the outside has a threshold/height difference, but that should (I think) fit without any porch.

I am wondering if the rear garage door might possibly be moved to the wall towards the terrace?

Here on the upper floor you can see the possible laundry chute in the children’s room. We don’t like that. But given the dimensions with the utility room below, there is no good place for it anymore -> it’s going away. So the corridor wall on the right, where it was previously, will be straight again.

In the study, the window has now moved to the left corner. This has the slight disadvantage that I can no longer use the corner as a built-in shelf, but on the other hand the desk and co. fit well there, and the shelf can go on the wall to the bedroom. By moving the window, on one hand you have the alignment with the door below, but also because otherwise there is no space for floor-to-ceiling windows with the conservatory below.
The second children’s room now also has a floor-to-ceiling window, since the shifted conservatory below no longer blocks it.

Accordingly, the exterior views have now been adjusted.
