This week, a new front door was delivered and installed at our house. In my opinion, the door was delivered too large and was not installed set into the wall opening but rather fixed from the inside against the wall. Unfortunately, I was not present at the time, and another family member essentially gave permission for this installation.

So now I’m considering how to deal with this. The company responsible says they measured specifically and everything is as ordered. I will hold back and spare myself and you from going into more detail on that.
For me, this was completely unexpected. The external wall is an uninsulated 45cm (18 inches) thick solid wall and will be fitted with external insulation. I even had the wall opening enlarged beforehand. I never would have dreamed the door wouldn’t be installed centered in the opening. Especially since there is currently no insulation in the opening, and at least the lintel still needs to be plastered. So I can’t add insulation in front of it anymore. Maybe a maximum of 1cm (0.4 inch), but then the door jamb practically lines up with the insulation. Since this is an older building and the walls are uneven, there are accordingly large gaps (which at least have sealing tape in them) as you can also see in the photo. This didn’t really matter for the interior plasterwork because no one expected a door to be installed here. The door frame still needs to be covered, and the gaps closed. The frame also has pre-drilled holes where it would normally be anchored to the wall opening.
What I’m really interested in is whether this kind of installation is standard practice at all? Assuming the misunderstanding is my responsibility, would this be acceptable from a craftsmanship or technical point of view? Because the external wall around the door opening cannot be insulated, I firmly assume this must cause a thermal bridge. Is my assumption correct?

Speechless... that a door supplier would even consider installation.
What I still don’t understand is where exactly you imagined the installation? Fully in the door frame belonging to the entrance, fully to the apartment side, or somewhere in the middle?
But that image link is totally unacceptable.

That’s an April Fools’ joke, isn’t it?I don’t think so. I rather suspect it was a wooden door in the same installation position as the previous one.https://www.instagram.com/11antgmxde/

Fully recessed into the door jamb belonging to the entrance, fully recessed into the apartment side, or somewhere in the middle of the opening? I would have assumed that the door would be centered in the opening, aligned there, and then insulation panels would be installed inside the door opening up to the door frame from the outside (and possibly even from the inside).

Then please show your order form and photos of the previous door. The specification for the door says "HET/plastic white/overlay door leaf/triple locking/TEKTONA/push handle/Dr 1150x2200," although we crossed out the dimension 1150x2200 with the note "Please wait. Probably 1000x2100" because we first wanted to see how we could enlarge the door opening, as the previous door was quite small at about 850mm x 1900m (33 inches x 75 feet).
Unfortunately, I don’t have a photo of the previous door. But it might be worth mentioning that there was a wooden porch in front of the building with its own entrance door. The door previously installed there was an interior door (left-hand hinge) and was mounted flush against the wall.

There usually isn’t any insulation in the jamb. Maybe I misused the word “jamb.” I meant the inside surface of the wall opening. Since this is older brick masonry, I assumed that some insulation definitely belongs in front of the frame (please correct me if I’m wrong) because the walls let through a lot of heat. As it stands now, the "shortest uninsulated path" between outside and inside goes through the width of the insulation strip between the door frame and the wall, which is 5cm (2 inches).
If the door is centered in the opening, my assumption would be that insulation matching the thickness of the door frame is applied on the inside of the wall opening just outside the door. This way, the dew point at low temperatures would be located somewhere within the insulation (or the wall). But as I said, I’m not a professional.
Where exactly should the insulation go? Would internal insulation be the right approach? If I want to reach some kind of agreement, otherwise we could have considered enlarging the wall opening even further. But if you tell me that the door doesn’t go into the wall, I’m just wondering what actually makes sense and what would be the correct solution.
