Hi Maria
I agree with Robert, definitely cannot be categorised as residential.
When I was at Lake Macquarie we had a Land & Environment Court case on this matter, back in the mid nineties, where the judge found a manufactured home estate could not be categorised as residential because of the regulation Robert mentioned. I am not sure of the case name, maybe Mullen & Others v LMCC, I think Justice Pearlman was the Judge.
Hope this helps.
