I just searched through the program. There isn’t a single hit regarding single-family house, single-family houses, or single-family home. So either you are lying or you are deducing something. In that case, please write how you derive this statement.
I was just about to ask where in the program it says anything about wanting to ban single-family houses, or even anything along those lines.
I have been wondering for a long time where this repeated thesis comes from, it is quite extreme. That in a big city, where many people live in a very small space, ONE MUST somehow restrict the space per person, as long as no fifth dimension has been found in which one could still build, that should be clear to everyone. But no party has anything to do with that, rather the laws of physics?
That someone demands that in rural areas no more single-family houses may be built, that would be new to me.
