Thank you for the open criticism (serious, no irony).
My own drawing is based on the original plan, which I have also uploaded here. The building was mostly self-built at the time. Accordingly, I re-measured the rooms to see if there were any deviations from the original plan. I also measured the modifications made over time, as there are no drawings for these. I have taken these three "basics" into account in my own drawing, as I described in my post yesterday.
