Hello Anne, is there a site plan of the property including development?
What I notice: you have to always pass by the front door from the garage. If there is also a classic step in front of the front door, it could become tight. Spontaneously, I would say that one could reconsider the orientation and position of the buildings; however, an overview plan and the information whether the ridge direction has to be like that are missing. Perhaps then someone might also have ideas on how to orient the living room more towards the west...?
If the garage stays like this: the current location actually lends itself to extend a roof up to the front door and skip the door to the utility room. That would provide storage space there, which you don't have so generously on the ground floor (provided the guest room should stay relatively free from your things).
Regarding the living room, I wonder what you want to use the space by the French doors to the terrace for? No furniture is drawn in so far, and it would block the doors.
If you actually have guests that often, the guest WC might offer too little storage space. The passage to the shower also looks a bit narrow.
Have you considered in the upper floor swapping the bathroom, dressing room, and office so that the office faces south? I find the idea of adopting the wide window from the ground floor in the previous office a nice approach, but personally, in favor of storage space, I would make fewer floor-to-ceiling windows upstairs.
From the other topic about the lamps, I got a bit of the impression that you want to watch the money (at least somewhat). With the house size, it adds up quite quickly. The fall protection at all upper floor windows, the transverse gable, also the very large paved area up to the garage, for example, will not be exactly cheap and you should keep that in mind.
Overall, I have to say, you can certainly build, but you probably want to hear what might work better or could cause problems. :-)
