Single-family house - Opinions on our design

Hello, I need your advice on how to get a better layout from the Elternbad - Hauswirtschaftsraum room - to Kinderbad.

Specifications:
Children's rooms are on the south side
Children's rooms should be approximately the same size. The Hauswirtschaftsraum room should have a dryer and washing machine, as we are building without a basement.

Thank you for your help.

Hello first of all
Drafts can only be evaluated and possibly changed as a whole.
Some things are missing here.
The upper floor indicates that the staircase either has the wrong position or is fundamentally the wrong choice.
The room layout is not advantageous: parents' bedroom, child 2, utility room... simply unnecessarily wasted, unusable corners in the rooms. Bathroom furniture should be arranged accordingly.

No tips from me, see sentence 1!

Indeed.

Requirements:
Children's rooms are on the south side

If the overall result is so skewed, it is a good reason to question all the requirements.

The utility room should have a dryer and washing machine,

It hardly matters what is supposed to go in there and even fits, when you have to be like a rubber person to slalom your way through as here.

The modern rubber person needs exactly 4 sinks and a children's bathroom for 4 people.

Thus also 3 toilets (incl. guest toilet), which of course is a bit unfair because then not all 4 can go to the bathroom at the same time.

First World Problems

Really, you need a children's bathroom? With that space you can really do more useful things.

Whether the room is sensible is another matter. In case of doubt, book it under luxury and luxury is allowed. However, with an 8sqm bathroom, I would move away from wanting a walk-in shower solution. The room is simply too small for that. That should already open up new options.

The floor plan looks very forced. The messed-up staircase, the pitch-dark hallway and all the offsets in the rooms ... this is more a case for the reset button. 105sqm of living space on one floor and not a hint of spaciousness visible.

. I would advise against having a walk-in shower solution in an 8sqm bathroom. .

Do you mean that for these 8sqm or in general? We have 4sqm and 8sqm bathrooms and that works wonderfully.
