Where to place the terrace/living rooms if the street is on the west side?

No no. We have already thought about the upper floors. We don’t need a utility room as such, but only a room for the heating system. One floor higher we want to do laundry, possibly in a larger bathroom or in a separate storage room, since on that floor there will be parents' and 2 children's rooms.
The moisture-sensitive items will go in the upper storage room. The resistant items will go in the garage. The vacuum cleaner will surely find a place in the lower heating room. These are our initial considerations.

Guests/office will also move up one floor. We’ll definitely be able to fit something in there if needed.

Where do you dry the laundry that doesn't belong in the dryer?
Where do your decorative items stay? If you think you don't need a utility room, you are the first and only family that doesn't need storage space.

Your children don't need sports clothes and change of shoes either...

Are you only creeped out by the room layouts? Because of the bathroom, heating, or the built-in slopes? The kitchen can still be arranged differently. I only made the sketch quickly without moving the kitchen because I wasn't sure about the 45 degrees. That was what was meant by the 45 degrees, right, or did I misunderstand?

Thanks for your suggestions. Laundry will be done on the upper floor, most likely in, let's say, a utility/storage room. We would plan it to be about 8 m2 in size. Basically, only doing the laundry on the upper floor is important to us. We would try to avoid an extra single room if possible. Therefore, the combination of laundry and storage room in one.
Alternatively, laundry would be done in the larger bathroom on the upper floor and the upper storage room planned to be about 7 m2. One of these two options should be quite good, right? Drying is mostly done by our dryer except for a few special items. If we ever need a smaller drying rack, we would temporarily put it either in the bathroom or the storage room (depending on what we decide). But we really don't have much laundry to dry.

Something like that - but without bending into the front yard,



and you probably took about 30° (which isn’t bad, and can actually fit better here)
