Trying to keep this on-topic:
Saw in a recent video that Fran is having problems with the neighbors who are smoking and using ozone generators to cover it up. She showed a rubber glove that had been eaten away by the ozone in her apartment. So now her health is at risk
So much confirmation (NOT!), that her choice of where to live (location and the specific building she chose), still have one or more, apparently 'nasty' people, potentially causing her difficulties and even possibly damage to her health.
That's the thing about if she owned her own, house (or similar), property somewhere. Nonsense like that (other people causing Ozone dangers), should be much, much less likely to occur (assuming the houses are separate/detached and don't have any shared usage spaces).
As far as I'm aware. Living in factory (like) units, is strongly discouraged, and/or NOT allowed by laws and regulations, in the UK.
Some (small) shops, have rooms/flats (typically) above the ground floor shop unit. Where either the shop owner(s) can live, or they can rent it out.
But this (apparent) concept, of mixed use factory (and living in the factory unit), doesn't seem to be something I've heard about in the UK.
But in the UK, you can get houses/homes, with connected/external workshops/studio units, which is at least, partly similar.
Usually, if people are living in part of a factory unit, it perhaps means some kind of illegal activities, such as people smuggling, is going on.
The UK's health and safety laws and stuff, makes it difficult, to fulfill all the regulations and laws, if it was used as a living space, as well. Also the planning application, would be difficult to get approval for.
E.g. If a perfectly legal UK house/home household, decided to let people live in their (unmodified) garage and/or caravan in the garden. That could cause big trouble with the authorities.
Even if you own a strip of land, you CAN'T legally live there (even in a caravan), without the correct planning application approvals.
