2 full floors, passage to garage, utility room under stairs

No, I don't want that either. In the pink forum, low voltage was recommended for the switch - I'll ask the electrician on Friday what he says about it.

So, instead of a landing, you simply make a half-spiral staircase. Now the utility room has a genuine 8.14 sqm without sloping ceilings, and under the stairs there are another good 4 sqm with sloping ceilings down to the floor at the end. The washing machine and dryer could also be stacked, placed on a platform, or positioned on the other side. In my opinion, the staircase doesn’t necessarily have to be made of concrete; it could also be a wooden staircase with risers. We reduced the hallway from 180 to 170 cm again.



The upper floor should be clear...

Don’t be confused by the Rs, Xs, and Os, we have temporarily placed sockets, light switches, roller shutter controls, etc. for testing.
