Bungalow 148m² site planning / floor plan planning

Then just remove the reduction there and straighten the wall. Where's the problem?

Now you really put a shack in front of him

Logically, it would continue further back, since you are going diagonally and the SW corner is entering the border area.

Oh, sorry, right. The OP only claimed to have implemented this...
Clear copyright infringement.

Again: the living room is only separated from the remaining living and dining area. It has a size of 4x4m and if that is too small for the chill corner, leave out the partition wall - then you have a proud approximately 59m². But I don’t want to harp on that - you don’t like the shape anyway. I’m only saying this because for you something like this



would also have to be a much too small living room...?!

Actually true... You could remove the partition wall and make it open.

When I’m home again and it’s not too late, I’ll redraw your design for myself. I’m out today...

Thanks.

Now you’ve put a barrack there for him

No, seriously: nice design. Children’s rooms very well integrated, in my opinion. It’s helpful to also look at the essentials and not get stuck.
Personally, despite the subwoofer, I would mirror the living room with the kitchen and provide the entrance hall with a double door to the kitchen. Transparency in the everyday area...

The gable roof is much more charming and modern than the high hip roof, which is not proportionate to the building volume at all.

In your floor plan, I find the living room very small.

Then just remove the reduction there and straighten the wall. What is the problem? This is not a suggestion that you couldn’t change. The idea counts, the possibilities.

I think my wife would like this design because she prefers the children's rooms to be at the back (south).

...
I myself would prefer the living room and kitchen at the back.
