Floor plan MGH 200QM - Evaluation ideas

Yes, agreed, it's not a plus, but there is still a window at the staircase, so it shouldn't be too dark again, and 1.30 m is not that narrow after all.

Have you ever stood in such a hallway? You might accept that in an apartment building because it's often not possible otherwise, but not in a new single-family house. And no, the window at the stairs won't let in enough light; you'll have to have artificial light on all day.
And yes, 1.3 meters is narrow. Every coming and going situation will turn into a conga line with a bottleneck.

Could be, the balcony door can open outward. The middle part could easily fit a sideboard or the rowing machine, and it gives a bit of air/space overall, we like it :)
Kitchen not next to the terrace is worse

In the picture it was a folding door, but that’s not the point. You can hardly walk around the table. It’s cramped. It doesn't help that the rowing machine has space there.
I would always plan kitchen/terrace adjacent in a new build. I wouldn't want to walk that path for every glass or forgotten fork.

Unless it's a 12mm drywall, the noise will probably be limited, the upper room is "odd" in shape but I don't see any reason why it shouldn't work as a study/guest room; not every room has to be boring and square.

Of course, that’s subjective, but you will hear the dishwasher noise. Also here, I wouldn't plan it like that in a new build.
And no, rooms don’t have to be square, but also not a corridor.

Sorry, I like some of the ideas, but you can clearly see that the floor plan is from an inexperienced amateur. A professional planner would be a good idea here. And without a drawing template.

Hmm, do you know the difference between a rough floor plan where not every detail is included yet and a finished detailed plan? Or what is this remark supposed to mean?

The rest of the house is furnished, so why is the bathroom not planned?

Have you ever stood in a hallway like that? You might accept it in a multi-family house because it's often not possible otherwise, but not in a new single-family house. And no, not enough light will come in through the window by the stairs; you’ll have to keep artificial light on all day long.
And yes, 1.3m is narrow. Every coming and going situation there will be like a conga line with a traffic jam.

I have now widened it a bit, so there is also space for a narrow window next to the door.

In the picture it was a folding door but that’s not the point. You can hardly walk around the table. It’s cramped.

Yes, you’re right, mirrored one time too many, by the way folding doors can also open outwards, the window question is still open anyway (hinged door, folding door, sliding door, no idea).
I have expanded the house 50 cm forward again. Maybe we'll put a bench against the wall instead of chairs, then it should definitely be enough.

Of course, that’s subjective but you will hear the dishwasher noises. Again, I would not plan that way in a new building.

I have now placed the cistern on the north wall, hopefully that will ease things a bit.
Professional help is still coming; we want to first deal with it ourselves and learn how difficult it is (yes, it is difficult), and just play around so that we learn what we like and what we don’t. It would be bad if I could manage as well as a professional planner.

Why is the entrance not on the side? The hallway is eternally long, narrow, and not exactly inviting

Why isn't the entrance on the side? The hallway is so endlessly long, narrow and not exactly inviting

Well, the entrance is on the east side, so I can get outside quickly, but then I have a pretty long walk there. On the west side there is a carport and cars, so I have to squeeze past them, not great either. If I put the cars somewhere else (north side) I'm back to the previous design. However, this objection came up often and rightly so, I will try to build something different this weekend.

Why don't you simply give your requirements to an architect or general contractor and let them do the work? I say it this way: luckily no one has seen my sketches. Of course, many other drafts from GUs have ended up in the trash, and those from the architect from the municipality as well. I didn’t like the positioning at all there. But it comes with input without operational blindness.
