sorry, but I just watched it live and have a completely different take.
She had been homeless for months, pregnant, on the streets and sleeping rough. Bristol has a housing crisis, ,and nowhere to put her.
In order to get her off the street and safe, she was offered one of these cabins. They are just like a small caravan, one room and a tiny bathroom. Yes it is small, and yes it is not great, or a long term solution, but it has been a stop gap to get her off the streets.
Her baby was born early, and no, I don't expect it was due to her being in a cabin, but much more likely due to her general overall health during pregnancy if she has been sleeping rough for months.
The council said they would look again at her case once the baby was born, and they have now said it again. I think she will be in a flat very soon.
