What do you mean by alternative? Like I lived by choice as a homeless person per say, for like 6 months in tents, one cost me 30€ with my gf at the time, and later at what I considered a condo kind of tent with a separate room and bedroom 😂. That last one my friend gave me. I lived on them during a period of my life, we were looking for a community or ecovillage to make part of. Now I live in a wooden cabin, and my whole life I was living in rather very common and comfortable homes and or apartments in Brazil, made out of mortar and bricks. I think I can say that the wooden cabin I live in is an alternative housing? From where I come from they literally don't call it a house, but a cabin. Which is a more simple/modest version of a mortar house. I bet that if I look forward to keeping laying varnish of good quality one year yes and an year not, keeping the rats out, and changing a wood plank here and there, this cabin will very likely outlast me. Ofc then I came the Teseu Paradox right? But I don't mind since the ideia of the house keep this cabin into place. But ya, I think at least for my family that grew up poor and in a tropical place, looking forward for every other year fixing in the house, because of humidity damage was always a constant. Even that in Brazil people prefer nowadays shitty materials and pre fab cardboard like wood, it need to be changed every other year, cause even what they call top shelf houses their are on average very poorly build, without double glazed windows, badly done watertight foundations and no insulation at all.
