I think all properties are owned by overseas landlords and investment megacorps though, finding housing is impossible, and the local council is powerless, they can barely even collect the trash piled up outside so space might be an issue. There are no public spaces here and those few that exist need explicit permission for anything, and I don’t think that will be allowed if there’s even a hint of politics, not that rich homeowners with a garden would be onboard for any such thing.
Also I think knocking on doors will result in a “what do you want?” followed by a “fuck off I’m not buying”, rather than anything useful.
