Floor plan revision, tips and experiences for improvement?

I'll give it a try:

- Slope on approach: I don't see the slope marked and it's too early in the morning for me to calculate it. So just a warning: I would make sure the slope is a maximum of 10%. Anything significantly steeper becomes increasingly problematic, especially in winter. (I still have flashbacks of trying to get up narrow streets with a 15+ slope in the snow with an underpowered small car.)

- Upper floor: I would swap some rooms there. Move the children's room from NW to SW, and the parents' bedroom to NW. This would have several advantages: 1. The parents' bedroom is not sandwiched between the children's rooms. 2. The child in the current NW children's room would get more sun (children's rooms are much more living spaces than bedrooms).

- Exterior facade: The window areas seem a bit asymmetrical and restless to me. (That doesn't bother me. However, there are people who will be bothered by that.)

- I assume that the house connections and such go into the technical room, not the utility room? Otherwise: utility room is far away. There will be suppliers who won’t go along with that. (For example, we actually had the requirement to plan the utility room facing the street.)

- It may be that storage space becomes tight here. Possibly I would consider integrating a mini storage room under the stairs. (Since the attic is gone, a lot of stuff will probably end up in the technical and utility rooms. Things like suitcases and such could then go into the stair storage room.)

Completely subjective:
- I don’t like the kitchen. Mainly because I can’t quite get it into my head. It could also be the time of day. (My apologies for everything today.)

- There are two or three spots where I would think about windows.
-> Gallery on upper floor facing east (I think that would do a lot for the hallway)
-> In the living room area, I’m absolutely not sure whether an east window for some morning sun would make sense. But then you would be visible toward the terrace, so not ideal either.

- Overall a very ambitious project. Apart from the placement of bedroom/children’s rooms and the window in the upper floor gallery, there was nothing that immediately struck me as problematic. (But: Paper tower today completely sleep-deprived and not accountable!)

Thank you very much in advance for the useful ideas, especially the window in the upper hallway will be planned. It was important to us downstairs to be able to access the terrace from the bedroom and to be able to sit outside there in the morning or evening, for example. Therefore, we did not place the children's rooms next to each other. We will definitely consider this.

Unfortunately, the slope is 2m over 10m, 20 percent. The further we slide the house down, the worse the view. The higher up, the less space behind the house for the marked seating area on hot days.

Yes, a walk-in dressing room from the bedroom is stupid, a bedroom between two children's rooms is stupid, a child in the north is stupid, an herb and vegetable garden that cannot be reached from the kitchen is stupid, and a dining table on the balcony that is not connected to the kitchen is also stupid. I cannot say whether the technical room and the pipes going upstairs cause problems (where does the shaft come into the upper floor?). I also cannot say whether the drawing means that the technical room is outside the thermal envelope. The entrance area with a wardrobe/utility room on the right and private area on the left is well done. But that's it: you go upstairs and meet... a wall!! Instead of a view. The kitchen is placed as a working kitchen in the back corner of the house, perpendicular to the entrance, far from the terrace. So groceries have to be carried across the house. If you want that, fine. I just don’t think that’s contemporary anymore. I wouldn’t feel like staying on the garage while the garden downstairs could be enjoyed with all senses. And if you look at the roof terrace, I have doubts that it can become a place of well-being. Apart from the one terrace door, it has no connection to the house (except for the window-cleaning balcony).

The slope is unfortunately 2m over 10m, 20 percent. The further we slide the house down, the worse the view. The further up, the less space behind the house for the marked seating area on hot days.

20% is very steep. Here, the first and last meters would probably also need to be flattened so that some cars don't scrape. I would actually consider (which also has disadvantages!) digging the garage into street level. Sure, you would then have to climb stairs into the house (annoying for groceries). Laying on your face in the snow or sliding away with the car would be even worse. Alternatively, rethink and place the garage further back. Of course, this requires larger redesigns. I would really recommend looking for a slope of 10%, 15%, and 20% somewhere in the area to get a feel for it. If you then say 20% works, then fine. I can only say: 20% would be way too steep for me.

The slope is unfortunately 2m over 10m, 20 percent.

That would be an absolute no-go for me.

What would the solution be then? Place the house all the way down, give up the view, and then be able to go out to the garden from the back of the upper floor? Then the garage driveway is practically at ground level, but there is also no light in the back of the basement.
