ᐅ Building a Concrete Garage! Three Walls or an Extension to the House? What Do You Think?

Hello everyone,
We are building a prefabricated house in NRW with the company Scanhaus Marlow Marlow. The building permit / planning permission process is currently underway. What was already clear to us beforehand is that Scanhaus Marlow Marlow is not involved in the garage construction. Therefore, we are currently focusing quite intensively on this topic.
After thorough research, we would like to have a concrete garage. For various reasons, we decided against steel. Unfortunately, it is very difficult for us to install a prefabricated concrete garage. The garage is planned to be placed on the left side of the house, under the roof overhang. The roof overhang has a height of 3m (10 feet) and is 1.20m (4 feet) wide. For this reason, hardly any prefabricated concrete garage manufacturers can install the garage at our location. Of course, there are also concrete garage manufacturers who produce "concrete individual parts" and assemble them on site.
We have now met with an architect who is going to design and estimate a masonry garage for us. He proposed building a garage with three walls plus a roof. The fourth wall would then be the house wall. From our house planning discussions, we know that no trades or fixtures may be attached to our house. The architect explained that the house does not have to bear any load or similar, as this is supported by the three garage walls. Of course, we understand that nothing can be attached to the fourth wall (house wall). This would be acceptable to us. An advantage of this idea is that we would save the cost of an additional wall and have roughly 20cm (8 inches) more space in the garage (due to the missing extra wall).
I have never heard of such a solution before. Does anyone have experience with this?
We have concerns regarding structural engineering, insulation, etc.
We would appreciate any feedback.
Best regards

From Bonn, it’s not far to (Neuwied) Heimbach-Weis. There is the Bims prefabricated construction company Hoffmann (not related or affiliated), which builds garages on site from pumice concrete panels, using a high-quality system, accurate to the centimeter and precisely fitting even when the shape is not rectangular.
Personally, I’m not a fan of precast concrete garages if they are supposed to have a double door, because basically, they don’t exist in that form. Instead, two single garages are placed one behind the other at a 90° angle, meaning there is a joint running across the entire width.
The missing fourth wall has to be replaced by a beam, which usually ends up being more expensive than building the wall. Therefore, I don’t really understand the point of this approach (apart from gaining usable width, but that also comes at a cost).

Hello kingstiefel
A prefabricated house is not a concrete bunker.
If you drive your car into it, you'll probably end up in the living room. You can get through the walls with a decent hammer.
StevenAt least the car stays intact then.
Place the prefabricated garage first, or have it built from a timber frame as well.
The price difference is probably around 200-300 € (220-330 USD), if it is even necessary. For example, using prestressed concrete elements would make this unnecessary. The architect and structural engineer will find a suitable solution.

I find the whole process quite complicated. Why not set up the prefabricated garage first, so there’s space for the truck? Then Scanhaus Marlow Marlow can build the walls and the roof. That’s exactly how it was done for us. Now the house and Rekers prefabricated garage stand side by side, and the joints between them are sealed with MS polymer, with an additional metal flashing on top. Karsten I don’t think it looks good; the garage is attached to the house like a growth. Unfortunately, it doesn’t integrate into the architecture at all.
