Built my own small house, learn the whole process from videos etc. Using solar panels for electricity. Live completely free of rent, it would be a one time purchase for the equipment to build and the materials. I would maybe have an outhouse for a toilet, or at least some practical toilet solution. My aunt and uncle has one of those toilets in their cabin where the crap gets burned, maybe one of those.
I would have a desk for the computer, electric outlets connected to the solar panels on the roof. Fridge, stove, bed. And I would make a big porch that is raised above ground, where I can chill when it’s sunny outside.
I’ve been so inspired lately by YouTubers who build their own cabins, I would seriously do it if I was a bit better off with mental health.
I bought a book on the internet about building your own house from scratch when I was in my early 30’s(I think). Maybe a bit younger. I fully intended to try it, but I never did it due to various reasons. It’s quite a project , though.
Its not hard doing framing and finishing but plumbing and electrical you need to pay a guy and they dont work cheap, or at all if they dont like what you built. House has to be connected to sewer or septic system and grid.
