Floor plan of a single-family house approx. 190 sqm with basement on millimeter paper

I am afraid, however, that this does not gain enough length to straighten the wall to the living room and kitchen?

I will sketch later at home how I mean it

.. by 125 cm width I mean the orange marked corner stub that you also have And pulling this around the corner is not considered in the floor plan drawing at the basement stairs by and would make the area by the slanted wall even tighter.

"Improvement process"

Taking smaller steps in the same hamster wheel is NOT an improvement process. I probably did not express myself clearly enough. You seem to have somewhat understood and tried to implement my suggestion to adjust the floor areas based on the budget. And it may well be that this did not create significantly more or more dramatic bottlenecks. Nevertheless, you cannot simply improve the quality of an excessively large floor plan by shrinking it. With the newly assessed room sizes, you should have embarked on a radical redesign (a relaunch, not a patch). So really from the ground up, as professionals do it: room schedule with sizes, distribution across the floors, starting on the upper floor, and so on. Even the Michelin-star chef boils water at +100° C.

I will sketch it out at home later to show what I mean

This is what I mean.. (I used an old plan) [ATTACH alt="75BD3229-892C-4477-9BB0-CD2C4F680241.jpeg" type="full"]71312[/ATTACH] I do not want to comment on the rest, such as straightening the hallway/dining area/slanted wall, because I prefer a different orientation and do not agree with the others.

I can also get along with the green-labeled version ;)

First, the floor plan with correct dimensions:


@kbt: I believe that does not mean the extra recess on the upper floor, but rather that the basement staircase does not require such a recess:
