Why is the design as it is now?
Own design based on many examples and personal ideas.

What is the most important/basic question about the floor plan in 130 characters?
Do we have major planning errors, useless layouts, construction flaws, etc.? We want to avoid mistakes or problems that cannot be corrected later.

Thanks for your opinions

Making the wall of the walk-in closet load-bearing seems completely feasible to me. I also had the impression that this could be included in the wooden structure of the shed roof. However, I have not yet spoken with a carpenter, and the structural engineer’s assessment is still pending. As I said, this is just a preliminary design for now.
But anyway, I will of course keep you updated.
Best regards,
Marco

In our case, the entire central wall is load-bearing. The gable itself is built using a timber frame construction method.
I just wanted to point that out. Maybe I’m wrong.

Well, I think the floor plan is still quite underdeveloped. The ground floor is fairly appealing, but what bothers me is that the terrace doors in the living area cannot be opened. If it’s going to be furnished like this, you might as well install fixed glazing or windows instead.

The upper floor is a bit of a disaster. You can basically forget about the guest room. The bathroom isn’t exactly a wellness retreat either, given its shallow depth and the awkward layout around the sink. It feels quite claustrophobic. Also, Child 1 sleeps right next to the parents’ bedroom wall, so privacy issues will resolve themselves.
The whole shed roof discussion makes things very uncertain anyway. It’s still unclear how much natural light will reach the upstairs corridor.

I took a quick look at it. I didn’t manage to come up with a satisfactory alternative on short notice. The attractive “bend” in the house wall becomes a problem upstairs. With the staircase and this bend, two important walls are fixed. This makes the rooms quite inflexible. Maybe someone else has an idea. So far, the only layout I’ve come up with is the following arrangement without a dressing room.

Ah, you want to open up the hallway upstairs: then you will have two ugly ledges above the stairs and the bathroom door instead of a straight wall all the way up to where the window is located.
