Where does the line get drawn?
Not sure exactly, but if it's mostly glass and you could pull it off and chuck it in the bin and the house would still be secure, weather proof and function, it's probably classed as a conservatory or lean to. If they took the doors out and knocked down the wall behind it, then it's an extension.
