It would be nice to learn how important design, art, materials, and textures are to the clients.
If you take a step back from the general efficiency and economic aspects, the first draft gains a clarity and elegance that can be very well showcased. The large hallway upstairs has a high gallery quality and allows an inclined art lover to change the exhibits (first let the children grow up a bit).
Correspondingly carefully selected furnishings can beautifully structure the large living space. In doing so, plan for room acoustics and appropriate ceiling height (3m). Of course, €2000 per sqm won’t be sufficient for that.
The second draft, by contrast, seems a bit petty and convoluted on the ground floor.
From practical and economic points of view, the draft is not the first choice, as circulation areas simply cost more than they provide, and there are plenty of them especially on the upper floor.
