Buying a property - real estate agent says “permitted” bedroom?

[Chris Fentiman]

Hi BP!

We’re a bit confused - buying a property (haven’t been able to get inside due to COVID) it states that the property is 4 bed 3 bath.

We couldn’t find the last bedroom in any videos, photos, or floor plans - when I questioned the agent - he said that there are 4 beds and one of them is a permitted bedroom (used mainly as a guest room).

Any idea what a permitted bedroom? All photos and videos were taken only a few weeks ago, so I can’t see they have done any work.

I was under the assumption a bedroom must have a wall, door, and windows that open to be considered a bedroom?
