While I'm not really concerned about it, I doubt that it would live up to Danish building regulations. I'm mean we pressure test our homes... then install ventilation systems because living in a house that can parse the pressure test would be unhealthy. We then continue to get headaches and stuffed noses because the ventilation systems aren't any good either.

Anyway, it doesn't look like this house would fit the required amount of isolation.
