Floor plan single-family house approx. 158 sqm with children's bedroom in the attic

I also rather see the courtyard as a dining terrace and would kill two birds with one stone with the kitchen location there, namely also a short corridor from the entrance to the kitchen. It might also often help to part with a corner in the south for a better entrance and thus a better developed floor plan.

Thank you for your ideas.
Unfortunately, I don’t know how to place the kitchen in the southwest and the entrance in the south. Somehow I don’t understand it or it conflicts.

That would explain the criticized head heights, because putting a gable roof “hat” on a one-story villa regularly isn’t possible or is basically a fatal operation.

Did I understand that correctly, fatal operation due to attic height? So rather choose a hip roof?

... the ridge height is entered as 8 m on average... ah, but I just understand, well, I saw it as a typo in the checklist that there was 744.9 and thought 7.44, okay then, but you can still see the really low standing height in the gallery area.

I already thought so and was completely confused.
So a different roof? Or fully use the height, there’s still a bit of room upwards.
Thanks for the answer.

Deadly operation because of standing heights in the attic (and possibly also other head heights). So a hip roof is even more deadly.

Well, actually I'm talking about a completely different design, which may gain from different conditions. Finally, regarding the stairs to the attic: they are incorrectly positioned. To function properly, they would have to run along the ridge wall so that the second level with standing height can be reached safely without accidents. An access to the courtyard can also be made through the hallway. Since you don't have a classic front garden, the entrance to the courtyard can also be opened architecturally as well as practically. I would probably rotate the house, place the gable to the south, kitchen and dining to the bottom of the plan, and living and garden to the east. Children's rooms in the south and then the stairs along the ridge wall.

I can contribute the following about the narrow hallway: We are also planning with a straight staircase and originally planned a 1m hallway. We then measured similar hallways in show homes and tested them thoroughly. That means we grabbed crates of drinks there and carried them from the front door to the kitchen, carried a laundry basket up the stairs, and much more. Now our hallway has a raw construction dimension of 2.26m; narrower would probably have severely affected the walls. Maybe you also have the opportunity to "test" a hallway.

Unfortunately, I have a main ridge direction west-east in the development plan.

I thought the western boundary is north-south. Aligning the house to the western boundary would, in my opinion, help. But it does not correspond to the ridge direction prescribed in the development plan. A pity. I would file a preliminary building request here. The streetlight is not in the way if you place the garage directly on the boundary.
