On the one hand, the draft is wasteful with square meters for long traffic routes, on the other hand full of bottlenecks in practical life – not an efficient use of space and therefore not of construction costs either. I wouldn’t build like that, because the implementation of recognizable ideas does not form a coherent overall work. Like a film with great characters that doesn’t hold up because they don’t interact.
What I think I can recognize are considerations about “How do I want to live in the house”. Extract that, then it will be easier to help. Examples:
[*]We want to live indoors and outdoors as soon as temperatures allow it, therefore the connection of the house to the terrace and garden is particularly important
[*]We want to leave each other privacy, therefore we want to separate the parents’ sleeping area from the children’s room.
[*]Our child, as a teenager, should be able to move freely with friends in the house, we don’t want to have to hear everything (all the time).
[*]We don’t value a representative entrance.
[*]We like watching TV, for that we want peace from the rest of the house and don’t want to disturb the rest of the house.
[*]In the garden we want to grow herbs and vegetables, therefore the kitchen needs a direct access to the outside.
[*]We like to be comfortable, refrigerator and favorite spot on the terrace should be close to each other.
[*]We want a low-maintenance house that does not become too big for us, especially not when there are only two of us or just one again.

From this, a professional makes good architecture.
If possible, take a few tours in Dutch model houses and get some inspiration. They implement a lot more innovatively and pragmatically than what is shown in the conservative German model house developments.
