>>2930797 (OP)Tinyhomes are romanticized because they're small, cute, and make sense on paper, but they're completely impractical unless you're a young adult or a very old person with no material possessions.
When the hype for them first started you used to be able to build them on a trailer for like $30,000 and it was a nice little apartment. Then of course because internet losers without any real intention of building one and no reasonable way to live in one, they got hyped up to $100k RV's disguised as a house. They should be well built, well thought out, practical, but most of all, sensible. No you don't need a copper roof and cedar siding on your trailer. Oak floors shouldn't be in a compact apartment. $100,000 sheds with plumbing make no sense every way you look at it.
Then theres a problem of where do you even put the fuckin thing? You cannot just find an empty field, tow your shack there and live in it. You generally need water, sewage, and electricity. Great, how many empty 1/8th acre plots are available? There just fuckin are none.
There is no "most practical" because thats different for each climate, the inhabitants, and the location its in or will likely be in. Then on top of that it has to be on wheels even if you have no intention of ever moving it again. But if thats your definite plan, why bother building a tinyhome at all? Just built a small apartment on a slab.
