It's really annoying that there are no dimensions indicated. How wide is the entire structure? Is the building envelope fully utilized in terms of width? And why is most of the terrace actually on the north side?
As it is now, it definitely can't stay that way because a utility room is needed. I consider it a sin to break up the bathroom upstairs or even integrate the washing machine there. That leaves only the ground floor, and in my opinion, this storage room next to the garage must be partially included in the thermal envelope. That's where the technical equipment will move in, and the washing machine will move into the current technical room.
If there is now a lack of parking spaces for bicycles, alternatively a shed must be added somewhere or the plan must be revised. But without dimensions, this is not possible.
