Based on some of the floor plans I've seen, architects also seem to have developed a habit of designing weird floor plans somewhere after the year 2000. I don't know why they thought apartments could need corridors with diverging or converging walls in the hallways, or why rooms without 90 degree angles are a good idea, but their decisions don't seem that far off the floor plans this tool generates.

These outputs are far from perfect but unfortunately they're not unrealistic.
