It's because real estate prices are skyrocketing in the UK. I saw a number of videos of people making strange micro apartments in London. Like one guy made an apartment that's just 2m wide or so to fit it between other buildings and another guy built it down instead of up and he's now sleeping in a modern basement because it was cheaper.
I've also seen documentaries about whores and homeless people in the UK. They're even living in old public bathrooms. That's not all. One woman bought such public bathroom and turned it into an apartment, so it's completely normal for people to live in their vans.
Why can't the government simply tel these people be. They are already living in poor conditions to make ends meet and save up for a flat of their own. Are their vans really such a problem for the city?
UK real estate prices in cities are artificially inflated. there is no actual NEED to do all this stuff apart from the fact that landowners buy up land, but dont build on 9of10 plots.. they sell the first plot high. and then build the next making the resell value of the first drop while strangely the initial first sell itself is used as a marker for value for the next plots sell.
by not just building it all in one go, they get to inflate the price and create more demand by limiting supply.
funny part is smart people work out rents/mortgages increase by hundreds a month so they just move to cheaper towns and commute in.
the cases of a guy making a 2m wide apartment or a woman converting a public bathroom is 1 case in a few million. and done so to make it appear like demand is high when reality its not.
as for the camper van scenario. its not really for living 24/7/365 its more like just somewhere to rest your head in a carpark 5 business nights a week and then drive to hometown for the weekend to save on travel costs
real estate agents hate it because no on is renting the 'buy to rent' listings they have so yea they want to make mobile living/camping uncomfortable by trying to get governments to force council tax on mobile homes and temporary homes so that people are swayed back into renting houses.
what happens next is requiring mobile homes to have extended MOT/safety reg checks fr carbon monoxide and electrical fault and fire risk tests. EG things like it cant be a panel van but a vehicle with multiple doors(exits) and windows
