/diy/ - Do It Yourself

This thread is very depressing. I always looked forward to build my own home in a long lasting way but it seems the techniques and methods are mostly forgotten or absurdidly expensive. How the hell is this "progress" when things like housing get more and more shortlasting and cancer inducing?

Anyway the question I have is, why the fuck would you build a McHouse that will fall apart in 50 years instead of buying a prefab house of some kind? Isn't it a better investment? Even a fucking caravan/trailer looks like a better investment than paying for a proper home and getting some shoddy shit with shit lifespan instead that will become a moneydrain from so many repairs or outright fall down.
