Opinions on our basic floor plan design wanted

We forego a window in the dressing room because we usually only stay in there either early in the morning or late in the evening anyway. For everything in between, there are more than enough lighting options.

However, this also means that an outfit worn in daylight can only be judged for its color coordination under artificial light. For the dressing room user type "Hit & run" (who sees the dressing room as a closet, grabs an outfit and rushes off) no problem – for the dressing room user type "Fashion show" a significant difference.

I am also wondering whether the hallway on the ground floor really needs a width of 150 cm between the stairway and the wall or whether 120 cm would be enough.

If I wanted to avoid a "switching" in the spatial perception at the transition from traffic area to living area, I would forgo the generosity break between living rooms and hallways.

I am the fashion show guy, I do like daylight to better judge outfits
120cm surely works for the hallway, but beautiful is something else

So my wife sees it the same way I do, we don’t need a window in the dressing room, there is enough daylight coming through the bedroom windows, in the morning when getting dressed you need artificial light anyway, and in the evening too..... Furthermore, I don’t know where you buy your clothes but I hardly know any store where you try on clothes in daylight, maybe at the flea market. And if it really has to be, then I just take the clothes two steps into the bedroom and stand in the daylight, an extra window just for that is wasted money.

but I hardly know any store where you can try on the clothes in daylight,

Exactly – a common reason for returns in brick-and-mortar stores. But well: personally, I also prefer the gained closet space.

With your roof pitch, an open gable is suitable, in which a roof window also fits quite well. Cleaning once a year from the inside using a ladder is completely sufficient, in case the remark comes.

Best regards in brief

With the basic shape of the house, that was also my thought, especially as a bathtub view I find a roof window appealing. However, that probably conflicts with the style "Jurahaus" (?)
