Introducing the three Welsh families who were hand-picked to live in a cramped miner's cottage at Stack Square, Blaenavon for four weeks.
"We're used to travelling the world but what could be more exciting than visiting a different time?"
"I'm afraid of rats and confined spaces so it doesn't bode well for working in the mine, does it?"
"We were probably selected as a joke to see how many of us can fit into the little cottage in Blaenavon."
Find out how we selected three families to travel back in time from over 150 applicants.
It was always going to be an interesting few weeks for the families says Philippa Davies who was on the selection panel.
There were no actors in Coal House but many of the local people of Blaenavon took part in the show.
We're gathering your memories and stories of coal mining and its impact on Welsh life.
