Bungalow floor plan 140 sqm (hip roof)

Maybe you can argue like that and actually think that in the worst case you would rather build a partition afterwards, if that really were necessary (which in my opinion will never be the case). Otherwise, I can speak from my own experience that black eyes disappear after a few weeks and broken teeth nowadays can be replaced with nice implants -
A bungalow feels free to me, which would be lost for me because of that; additionally the options in kitchen design.
2.80 m is a really pleasant ceiling height!
The entrance area looks good, I would generally pay attention to a rather light-looking appearance

Good morning Bungalows are not really my thing, but I have to admit the left hallway would be too dark for me. And the toilet without a window wouldn’t be my choice either (but that’s something people have different opinions about anyway ) I just don’t have an idea how to do it differently.

Make the window in the living room (right wall) floor-to-ceiling?

your living room dimensions do not match the drawn furniture. You have 6.40m available, there must be at least 1m space from the kitchen to the dining table (which is already little, when you come out of the kitchen, the dining table is directly in front of you), then about 2m dining table length (and three chairs do not fit on each side) and again 1m to the couch, and already 4 meters are gone and only 2.4m remain for the living area. In your drawing, it looks like a 2.40m long dining table and at least 3m couch corner would fit, but that does not fit into 6.40m.

Best regards
