Single-family house 150 sqm - Quiet village, space to the neighbors

Considered, thanks, may/can’t be higher.

So, you have therefore drawn a double bed in the study.

According to recalculation, the room has:


approx. 395 cm raw construction width and approx. 282 cm room depth. Thus, a 3m wardrobe does not fit at all. The door, as drawn, must be moved further to the left according to the plan anyway, because there are only about 45 cm to the right of the door... for a sliding door wardrobe, however, at least 70 cm should be planned due to the doors.

With a room width of 394 cm, 70 cm for the wardrobe, approx. 91 cm for the door (tight door), there remain 233 cm for the bed and space to the left wall.

I claim, you are sugarcoating the dimensions and intentions of your house.

And by the way, I have never experienced anyone as resistant to advice as you. The question why you even posted the floor plan here actually arises for me.

Besides, our hands are somewhat tied if we want to build "even" bigger.

No one says that.

We find it sufficient like this,

Aha, with sufficient you achieve nothing.

A 3m long and 80cm wide one with sliding floating doors fits in easily.

If the drawing is correct, then no.

The bed comes to the wall facing the corridor, fits easily, even with a walker.

If the drawing is correct, then no.

If you find everything sufficient, your post here was unnecessary.
For me, there are gradations to consider like satisfactory or even good.
And I agree with Katja in her direct choice of words: what matters is the flow of family life rather than the guests' nitpicking.

0. mitigate the wind tunnel; 1. give the staircase a more youth-appropriate neckline; 2. mess a bit with the facade symmetry. Can you explain that again in more detail?

0) structurally prevent every little breeze in the duct from being turbocharged into a hurricane – by alternating narrowings, diffusers, or simply putting a stopper at the back; 1) the parapet height of the staircase is offside and even makes pastor's daughters blush; the window distribution is terribly stiff.
