Rectangular single-family house on a narrow plot

From the terrace to the south, towards the main part of the garden, a privacy screen (hedge) is drawn – what is the reason for this? This is how you artificially make your garden smaller. I would try to orient the floor-to-ceiling windows more towards the south and west and open the house in both directions (possibly corner windows). This does reduce the usable area of the kitchen a bit, but this way you visually lose 250m2 of garden. If the area to the south is not attractive (neighboring buildings or similar), the position of the house could still be adjusted. But for that, you should ideally show us an aerial photo (Google Maps) or site plan. The street names can gladly be blacked out.

The house should also open towards the garden. The southern light is very necessary in the house during winter. Basically, the path to the utility room (which one takes several times a day with a ladder, vacuum cleaner, laundry basket, or shopping) is much too complicated and long. And all this just because of a shower—who is it for? I don’t see a guest room there.

And by the way:

Please always abbreviate children’s room as children’s room. Fortunately, the times of a KZ are over.

A staircase start directly at the entrance hall would not be my choice either. I would usually assign a slender staircase to a slender design—it looks the most elegant.

The utility room is very inconveniently located, you have to go in there very often, get cleaning cloths (to clean the stairs, for example), a hand broom to remove dirt in the entrance area, drinks to bring them upstairs, the vacuum cleaner, the laundry basket, etc. ... and then you always have to go through the living area and the kitchen, that's very inconvenient.

I can understand the west terrace very well, but as I see here especially from October to March a dark house, even if it is in the middle of the day. I would, for example, always orient bedrooms rather to the northeast and not to the west. In the west it gets full sun again in the summer all afternoon and evening, making it pleasantly undesirably warm in the evening. In general, the rooms on the upper floor and their entrances, especially bedrooms, are arranged so that you always run into the wardrobe blocks. I also see the problem of accessibility to the storage area in the utility room. Especially with your planned 2-person household, I would create space for washing machine/dryer on the upper floor.

We have a similar house shape, so I know that the "corridor" must be well thought out so that it doesn't appear that way and some people don't like it.

I agree with you, we also have such a "corridor" and it sometimes feels a bit oppressive and just long... I wasn’t really aware of that back then either. You definitely have to loosen it up somehow, perhaps with a fireplace as a "room divider" or something like that. Maybe a bay window, like an outwardly extended dining area, could help too. For us, it doesn’t feel very cozy because it’s very long and you can see everything all the time, and because the dining table is uncomfortably placed in the middle of the whole room.

I briefly skimmed through your own thread... oh dear... things really got heated there—
I thought to myself that you can definitely make something nice out of your house. Just take someone with you who you’ve seen can design spaces beautifully. I think you just have to realize that designing something nicely isn’t your thing. So look for that person (or those people). Maybe your partner also can’t do it, but that doesn’t matter as long as you both find the right “professional” for it and trust him/her.
From some of your pictures, I see that you like nice things but just don’t manage to put them into practice; I’m the same way in some areas, and then I just stay completely away from it and look for someone who can implement it stylishly.
As a young guy, I once did it so that I commissioned a woman from the field who seemed competent to me to design my apartment nicely; I paid her well for her time. I thought the result was great afterward, and until then I simply kept my mouth shut and paid for what she recommended.
But you have to be prepared to let go of a piano, your fireplace, dining table, etc.
Until now, gray was considered the epitome of gloominess, but as we can see nowadays, you can create beautiful things with it.
And... if it really should depend on one or the other window, then I would get rid of it quickly and have it enlarged. In my old house, I didn’t just use the big Hilti once or twice or had doors moved... but only AFTER you find someone with appropriate, modern design taste.
