The wall to the living room can, as before, be continuous .. under the stairs or around the stairwell. However, it must be clarified how the stairs on the upper floor are positioned. It could be tight there. Ideally, with the planned floor height, there would be 17 risers with 17.98 cm each and a tread depth of about 27 cm. This would result in a staircase length of around 460 cm. With the floor height, the upper floor hallway may overlap 1 to 1.5 steps from the ground floor.
