Very first floor plan draft of the ground floor

Possibly roof windows in the area of the stairwell?

That could be done - provided the underside of the roof is open - but it wouldn't be the real deal: for stairs, even light is more favorable.

If I suggest that, the immediate response is, how am I supposed to clean that?

It would be your dirt, so it doesn't matter to the other discussants. Only if one assumes that you like it clean, a hint is appropriate if that would require a regular subscription with the scaffolding company.

A little update... I still haven't solved the problem with the light in the hallway. Also, I would like the kitchen to be at the top of the plan to have direct access to the / terrace and the garden. Unfortunately, I think that won't work as long as we plan the pantry.

Swap the [wc] and pantry, as well as the living room and kitchen, problem solved ¯\_(ツ)_/¯

Unfortunately not, because then the kitchen would look strange if there is a door to the pantry

Something like that can be solved through a "secret door," tall cabinets with a hidden door in the middle that from the outside looks like another tall cabinet.

I have to take a look, maybe I'll just move the garage door and place it on the long side of the house at the bottom of the plan
