The finishing work will be somewhat more complex, as among other things, baseboards also need to be changed. In terms of price, it should still stay within the (door) frame.
Another small milestone. Our indoor staircase has finally arrived. It was a tough process until we made our decision.
My spotlights also cost me sleepless nights since I had to measure out, drill, and plaster them without the staircase. I calculated the individual positions from the plan and kept measuring starting from the meter mark. Conclusion: The effort was worth it.
