The estate agent that told me the number of bedrooms in the house I eventually bought didn't seem to know that. Seemed to think because some idiot filled in the doorway from the main bedroom, ensuring it was too small for both bed & wardrobe, and put another doorway from the enclosed bit onto the landing, that increased the bedroom count by one. Good job the number of bedrooms wasn't a vital thing for me. But disappointed folk seem to think the house would lose value if I undid that garbage conversion.
