I watch parts of the tiny house show, ocassionally and can't get past the fact that any travel trailer or motorhome is better designed, ands does everything better than those heavyweight sheds on a utility trailer.
Especially ridicules for those on the shows that want to move about every few months.
They are all the same, narrow rooms, with a loft bed. even an RV wet bath is better than the baths in the tiny house.
That said, the shed house would work for a weekend lake house, except deed restrictions on lakes often state minimum square footage to keep out the riffraff...
The real hoot of it is, they are often placed in mobile home, or RV parks
