While he does maintain a persona for the channel, it not all fake, He is fairly transparent about some of these things he did mention about permissions etc, his behind the scenes videos show a bit more usually.

I would say it is more artistic license in the story he is saying rather being artificially synthetic.

He's done work for "minstream" TV before, but in reality, as with a lot of Youtube, it's only him, his wife and a few friends.

The original bunker had to retroactively apply for planning permission: https://planning.southkesteven.gov.uk/SKDC/S16-0017/1288446....

Of course it's way more organised that it first seems, because it is sponsored after all, but he does seem rather fly-by-night o all his things.

He said he was going to do a load of other projects with that bunker (including ventilation systems) but they never happened.

He has himself, Rick and Tom. He’s said before he’s a one man band when it comes to filming, editing and the business.
