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 ask at the beginning of the week. Yes, they are around 110 cm.

Today the offer came back. Of course with items that ultimately depend on what actually happens on site, as with the foundation, but I now have a target figure. It’s a gross 12k€. That means with the foundation together I have costs just under 50k€. A basement would probably cost a lot more. (But out of interest, I asked the foundation/sockel wall builder for a rough estimate of the difference. They also do basements, so that should give me a guideline without wasting too much effort).
(With the adjusted plans attached here, it will probably be around 14k€, or so I estimate, since the garage extends further out and accordingly requires more substructure.)

Otherwise, there are new plans. I already have some comments on them, curious to see what you all come up with.

The ground floor. The conservatory is now 4.50 x 1.25m. They don’t have one with entirely glass in their offer, hence the option drawn in with flat roof windows, if I insist on that. But they advise against it, shading and costs speak against it. We don’t like that either.
If the conservatory doesn’t appeal, I could also have a bay window there, which would be cheaper – but also significantly less window area. That of course contradicts the desire for lots of light, which is why the conservatory is drawn in for now.

What strikes me first are the (in my opinion) large wall sections that protrude in there. I assume they are needed for statics, but this is a point I will ask about whether it can be done differently (or if different then it immediately results in bay windows). Naively, I’d hope a large steel beam above would do it as well. What do you think about those?

The guest room currently has a way too small planned window, only 72 cm high. Same height as in the kitchen – yay, symmetry. But I don’t care about that; a 125 cm one should go in there to have enough light in that room. The one in the kitchen is only so small so we can have a proper sink underneath.
The laundry chute drawn there is a suggestion from them – we had planned one and did not move it along in our wishes. It would come out there. Since that does not make much sense, it’s still shown as a note, but a new proposal is already drawn on the left in the utility room. However, that has disadvantages upstairs, because the space for it then hangs in the kids’ room. Space-wise it is okay in terms of quantity, but the corner makes it practically impossible to sensibly plan a bed or a wardrobe there. We will probably omit that entirely. Nice feature, but not essential. Laundry bags go into the bathrooms, and then when running the machines, they have to be carried...

The utility/technical room is now nicely big and has a door planned to the outside. Although I would still like to swap the arrangement of washing machine/dryer and sink there. 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 facing the terrace?

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

In the study, the window has now moved to the left into the 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 shelves can go on the bedroom wall. By moving the window, you have on the one hand the orientation with the door below but also because otherwise with the conservatory below there is no room for floor-to-ceiling windows.
The second kids’ room now also has a floor-to-ceiling window, as the moved conservatory below no longer blocks it.

Accordingly, the exterior views have now been adjusted.
