Watching the special program ‘24 Hour Build Special’ from the seventh season of ‘George Clarke’s Amazing Spaces’ (from the English public broadcast television Channel 4 in 2018) I learnt about ‘Tŷ unnos’, the Welsh folk tradition (shared with many other places in the world) of building a house in one night.

The tradition says you can build a house for free on common land if it only takes you a night.

Did you know about this tradition or something similar?
