Single-family house - approx. 150 sqm - without basement - Who has ideas? Thanks

On the ground floor, it would be the only door with a transom window .... for the living area, a door with a fixed sidelight is planned.

Mmh, well, at this point I find it a bit pointless – at least if it's purely about the purpose. After all, both rooms right next to each other have windows.

Your favorite object...
