The goal was to place the pool on the south side, in front of the sauna/fitness room. Also, to have the children's room facing south and to prevent the garden from being visible from the driveway. I included a knee wall height of 1m (3.3 feet). I have not yet been able to read the regulations regarding this, or I’m unclear why you didn’t have one. Does the two-thirds rule not apply?
Thank you very much for the proposal and your effort!
The new floor plans are definitely refreshing and might be applied (at least partially).
However, in your design or drafts, the maximum eaves height of 3.50 m (11.5 feet) above the finished floor level has not been taken into account. Since this is mandatory, the plan cannot be implemented as is. Or is it possible to override the two-thirds rule by reducing the eaves height? If not, unfortunately, the balcony facing south as shown will not work either.
Another downside to this model is that in the morning you would have no sunlight, since you would be sitting in the shadow of the house.
I like the arrangement of the double garage with the front door beside it. This way the garage and front door are next to each other, and the garden remains continuous and undivided. Although the driveway is on a slope, I think this can be solved somehow.
I am just wondering how the terrace on the west side should be supported… with angle supports or L-shaped retaining walls?
Does your software perhaps also provide views from the other sides? If yes, it would be great if you could share those here.

Because I have been thinking about some sketches myself, the very large garage caught my attention. Is it meant to be that big? I see internal dimensions of 8.13 x 8.13 m (26.7 x 26.7 feet) on the plan.
We have a garage around 7.05 m (23.1 feet) long and 5.80 m (19 feet) wide inside; it stores an Audi A6, a BMW 4 Series, three bicycles, one child trailer, and 3 meters (9.8 feet) of heavy-duty shelving with 60 cm (2 feet) depth.
An extra meter (3.3 feet) width would be ideal to avoid having to move the bike trailer through the back door when both cars are inside, so about 7 x 7 m (23 x 23 feet). Why do you want so much more space?The garage size is probably so large because the architect’s task was to design the terrace as big as possible. Since the terrace is on top of the garage, this is the result. But of course, the size should be reduced there as well. On the other hand, I really like it when the garage is spacious, so you don’t have to worry about hitting the door against the wall or car all the time. Also, you need to think about storage space for bicycles and garbage bins.

However, in your planning or drafts, the maximum eaves height of 3.50 m (11 ft 6 in) measured from the top edge of the finished floor was not taken into account. Yes, I hadn’t noticed that and was already puzzled. That’s really unfortunate for you. So, you basically have no knee wall. With a maximum roof pitch of 35°, you can’t really do much either. That’s why there are all those dormers.
In this specific case – with the design that the original poster seems determined to just tinker with rather than completely redesign – I don’t see the otherwise rather large garage being significantly reducible: not in width because of the central pillar, and in length, where it might be about one meter (3 feet), it would negatively affect the terrace, at least on the street-facing side.

Hence all the dormers.Yes, that’s really frustrating. But the municipality wants to prevent three-story houses from being visible from the south.
True... without the dormers, it really wouldn’t work. But again, you always have to find some kind of compromise.
I find the municipality very approachable. I don’t find dormers annoying at all; in the attic, I prefer standing by the window rather than in front of or below it. And you can manage without a knee wall as well – after all, it’s better than having one that doesn’t quite fulfill the function of a knee wall.

And it’s possible without a knee wall too – at least that’s better than having one that doesn’t quite replace the wall section.Well, the “annoying” comment was more about the eaves height. Because of that, you mostly only have sloping ceilings upstairs, and the dormers can only be arranged over 50% of the roof length.
