Solid wood walls are theoretically possible. In practice, they must be installed as soon as a floor is built before the ceiling is added. It is more expensive than masonry.
Funny - there: someone asks in the reverse mix. Would you like to share with us your motives, what you expect from it?
We are contemplating things like a pantry or here and there a little corner that should serve as storage space. In the USA, for example, a lot is built out of wood, and it is very common to have many small extra rooms. There is then a built-in closet in every room, there is a coat closet in the hallway. Then there are linen closets (i.e., built-in cabinets for towels, bed linens, etc.). I imagine building solid walls for all this to be more complicated and expensive than doing it with wooden walls. Am I wrong?
The question is rather whether it is necessary. You have to take the niches into account in the planning, otherwise you will have annoying corners everywhere. Consider whether you might replace entire walls with cabinets. Where it doesn't matter that the soundproofing is not optimal. For example, bedroom dressing room, wardrobe all-purpose room.

Oh, we wouldn’t actually find that annoying. Rather cozy.
We’re just wondering if it would be better, more practical, or cheaper to have such "unimportant", non-load-bearing walls built from wood.
