I've just bought a house with a very usable cellar - it's been insulated and has heat and light and fully decorated - all with planning permission. We bought it as a non-habitable room for storage as it didn't meet building control. I've looked at the regulations and I'm not sure why it hasn't been approved although I've heard that our council likes ceilings to be a certain height - but there doesn't appear to be any restriction in the regulations. Can I get a private inspector to come and confirm that it meets building control if I'm not doing any building work? I would like to be able to describe it as a study or bedroom in the agents details when we come to sell it.
