I didn't quite understand the part about the ventilation.
That's exactly what I meant:

Floor plan: house with supply and exhaust air; rooms on the left, kitchenette, shower and toilet on the right.

I don’t understand...
The column is empty, so what?

Exactly. Air flows through the hallways.
Which is actually quite normal, as long as the rooms are not too large....

Hallways, clearly. But is the exhaust air in the living room (and all bedrooms) supposed to exit only through the gaps under the doors?
