Floor plan design single-family house (167 m2) feedback

You should realize that you are sinking hundreds of thousands of euros into a house that will become a bunker. Even if there is a completely open window front on one side, this is not a house you want to pay 500K and more for. Even an apartment has more window sides. It feels like being in a prison cell. I would advise you to stop this nonsense.

If you want to use the area, tear down the halls. Are they important? Are they needed? If yes, really all of them? The question would be anyway how they look and whether you would want to live between these halls? Are they authentic and somehow nice?

Or use the area that the property otherwise offers, if it is allowed to be built on.

Okay, okay. I'd better post a photo of the current state. Please let me know if this changes your opinion?!

What kind of building is that supposed to be in the photo?

build directly onto 2 buildings so that there are no windows on 3(!) sides?

2.. Windows are possible on 2 sides. And this also applies to every middle terraced house, so I do not even find that unusual or absurd. My glossy books show almost only such niche solutions. They are interesting, but mostly very expensive houses. And yes, I understand that many cannot relate to such houses.

It feels like being in a prison cell.

If you do it right, something like that can also work without the prison feeling.

I am fascinated by these designs and discussions. Usually, I get involved with them.
But not here, because there are simply too many situations that are supposedly there but are neither explained nor shown.
If one thinks a docked hall offers the possibility for a window over 2-3 meters, then I want to see that.
If, for a large room that is not bathed in light anyway, a concrete slab is also added in front, then I have no idea anymore.
If a chimney stack is attached to a hall, then I cannot believe it for fire protection reasons.
And if you have to cross the corridor on the upper floor to pee just before taking a shower, then there is absolutely nothing solid that you can grasp. And then they talk about an involved architect.
Now I am supposed to google the other thread to somehow get an overview. Respect!
The minimum would be drone and Google Maps images.

Windows are possible on 2 sides.

The adjacent halls on the ground floor only allow windows on the west side.

You mean the strip of light on the ceiling makes it comparable to a terraced house in the middle?

In the north, however, a higher-placed, long window can be installed above the dining bench to make the room feel a bit more open.

Let me doubt that.

Okay, okay. I'd better post a photo of the current state. Please let me know if that changes your opinion?!

Yes, wonderful - now you have gained space. The hut can go, right? That looks a lot like junk. Hopefully, no asbestos was used.

The building is the garage…

I am intrigued by these designs and discussions. Mostly I engage with them.
But not here, because there are simply too many situations that are supposed to be, which are neither explained nor shown.

Okay, then I no longer expect any feedback if the available information is not sufficient. I understand that.
An elevated window/light strip, or whatever it is correctly called in technical terms, would extend here over a length of 2-3 m.

If for a large room, which is not even cared for by light, one also places a concrete slab in front, then I have nothing more to say.

This idea has been discarded and is no longer in this plan! However, I still consider a roof over the entrance and terrace essential.

And if you have to cross the corridor on the upper floor to pee just before showering, then I find absolutely nothing substantial there that one can grasp somehow.

Interesting view. But I absolutely do not see it that way. For example, I do not find it good to have the toilet in the bathroom. Matter of taste.

A raised window/light strip, or as it is correctly called in technical terms, would fit here over a length of 2-3 m.

Still makes a room appear like a basement room.
