Old building renovation (1966): Two-family house - floor plan sketch

I don’t quite understand the access to the house, where is it?

Best regards

Staircase "between" the basement and ground floor - on the plan you can see external steps on the ground floor

Whether the cabinet xyz is placed turned to the left or to the right we leave open at this point.

This is, in itself – that is, excluding the insight that one would have preferred to place a new partition wall 10 cm elsewhere – as relevant as the opening direction of the room door and the window.

This is in itself – so already excluding the realization that one would have preferred to build a new partition wall 10 cm elsewhere – as relevant as the direction in which the room door and the window open.

Since I still have to make a final decision whether the partition wall needs to be moved 10 cm or the door should be hinged the other way around, when I build the wall or install the door, we still have some time

Then use the time and set up your house. Until the sledgehammer falls, also make sure the measurements fit.

I don't quite understand the entrance either.

I would try to open the wall from the dining area to the hallway/entrance/staircase more, so that the staircase disappears.

The wall must go where it was approved.
