Floor plan design single-family house 150 sqm - tips for improvement?

Basically, the floor plan is okay. However, I also fear it is a bit unbalanced in terms of space.

Unfortunately, pulling the living room out by 50 cm doesn’t help either; it remains just under 6 m wide ... so basically 2x3 m cabins (furniture store ) for dining/living.

The parents' wing is designed like this ... I would definitely want direct access to the bathroom and not have to go through the hallway.

I really don’t like the many shallow windows on the upper floor ... for example, in the bathroom as well. That always gives a basement feeling.

6 meters is too narrow Draw proper furniture without fail. We have just over 7 meters for dining and living It works If the table is fully occupied, you can still squeeze past Our sofa is quite slim However, I notice almost daily that the half meter I would have liked more is missing Your room program is sporty in terms of space

Yes, we also don’t like the narrow windows. As mentioned, we totally dislike the front view because of it. Apparently, though, it is due to the room concept since the windows were adapted to the rooms.

6 meters is too narrow Draw proper furniture in for sure. We have just over 7 meters for dining and living It works If the table is fully occupied, you can still squeeze past Our sofa is quite slim However, I notice almost daily that the half meter I would have liked more is missing Your room layout is ambitious for the area

That means 7m by what?

It’s not about “just something.”
You need 3 meters for the dining area if the table is placed lengthwise.
40 cm for the TV stand, 10 cm for plaster and baseboards, 70 cm for a coffee table plus the depth of the sofa.... We don’t know your furniture.... Let’s assume 1 meter (mine is 1.20...)... then 60 cm remain for the walkway around the coffee table. That means: the table has to be moved when the TV stand is being used.
The position of the sofa is uncomfortable anyway. You sit on the sofa and feel like you’re in a busy hallway. You’re not even allowed to be sick or lie exhausted on the sofa, everyone is constantly passing by.
It would be better to swap the living room and kitchen, but your wish was certainly the door and passage to the utility room.

Times 5.5 m
Does not help you. The problem is as written by YPG
