Single-family house - approx. 150 sqm - without basement - Who has ideas? Thanks

Update:
- Building permit is granted
- Agreed with the shell builder

The preparations for the foundation slab started yesterday.

I have another question about the bathrooms (I basically have 3, ground floor, upper floor, and attic)

- The ground floor layout could be improved? Would you place the door further up – that is, up to the wall?

- I like the architect’s upper floor layout, I find the alternative better, what do you think?

- How is the attic bathroom layout? I think the overall room arrangements are great, would you swap the bathroom (south-north) and storage room (northeast)? Thanks again here

For the shell builder, it is no problem to make a different positioning afterward.

Thank you all

Would not change anything on the ground floor.

On the upper floor, I find the new design interesting. Unfortunately, I can’t really imagine anything concrete about the mirrors. Where are they placed? How wobbly or firm do they look? You’re looking against the window light, right? Or is there a wall in between? You just forgot to draw a second window? Overall, it would be too cramped and annoying for me to constantly run around the center in circles. I would stick to the original design and also add a window there. Or someone might have a third idea.

On the attic floor, pay attention to the slopes. Swapping the bathroom with the storage won’t work, since the latter is almost entirely below 2m.

On the attic floor, watch out for the slants. Swapping the bathroom with the storage won't work, as the latter is almost completely below 2m.

Ground floor bathroom:
ok, then ground floor is done

Upper floor bathroom: indeed, narrow standing mirrors are proposed there, but no prior thoughts were made about it. A second window to the north? That might slightly harm the north view? In the original design, the toilet bothers me; you come in and see it right away. A third idea here would be nice or helpful!!

Attic bathroom:
ok, done here as well

So only the upper floor bathroom remains, which could still be improved.

Thank you!!!

You also don't have a north-facing window in the living room. Why not? You can look outside. It's nicer - trust me.

You don’t have a north window in the living room either. Why not? You can look outside. It’s nicer – trust me.

Alright, I do believe you, what kind of window could one take, I mean in terms of size? I just thought from the arrangement of the view it might not fit.

The exterior view is also important, that's true. Have you already got all views all around completely?
