I remember being called to new corporation house near christchurch about 15/20 years ago. New tenants in a new house, we were asked to go in and assess snags.
A guy was sitting in the sitting room watching TV (a can of lager remote control etc).
It was a week day lunchtime.
Every internal door downstairs was cut in half. The top half closed , the bottom open. When asked why he cut the doors in half, we were told that he could not stop the kids banging the doors and that this was his solution.
