Floor plan design single-family house with around 150 m²

Or are we already at the edge of the building envelope? I can't tell.

As I see it, there is no proper building envelope, but only on one side a building line (the street-side building line with neighboring house corners).

I find the number of wishes quite large compared to the number of square meters.

Ditto. At the top two places on my cut list are the children's bathroom and the cozy fireplace.

Simply mirroring quickly is unfortunately not possible, the OG is not symmetrical. The children's rooms become smaller and the bathroom larger - mmmh.

Oh, are your measurements binding? [emoji16]

The external dimensions indirectly yes: if the house floor area is

I consider the internal dimensions as non-binding.

Correct, just because of the not quite centered staircase, mirroring only one floor would mean that room dimensions would have to be adjusted. Where that would become too tight, the house would have to be made wider overall.

Simply mirroring quickly is unfortunately not possible, the upper floor is not symmetrical. The children's rooms become smaller and the bathroom bigger - mmmh.

I think the bathroom should definitely be moved to the lower left - so that it is above the utility room/guest bathroom on the ground floor. Otherwise, you have the problem again with additional downpipes, etc.

I find the number of wishes quite large compared to the number of sqm.
On the other hand, the closet with 2.5m is decent but tight for 2 people, right? OK, the wardrobe downstairs is also 2.5m x 0.6m, but otherwise it gets tight for the ball gowns.
Would you maybe rather sacrifice 1m of garden area for more depth and thus more versatility? Then the Maxime will also work... Or are we already at the edge of the building plot? I can’t tell.

I would rather not sacrifice more garden area. I already find the house oversized as it is. I would rather reduce something in the ground floor office or make the children's rooms smaller. The living area could maybe also become smaller (narrower and less deep).
