Why don’t you let an architect do it? Sorry, but I think it’s lacking in every respect..
For a layperson, I think this is already quite a good painted basis for discussion to visualize the wishes towards the architect, and you don’t have to prepare it more “appropriately.” But mind you, an architect should be put to work afterwards, and not a general contractor’s drafting clerk. In the latter case, unfortunately, the journey would go towards Senkjuforträweling ;-)
