This huge house is slowly succumbing to the elements. What I find remarkable about it is that it has been left like this despite it being huge, in a really posh expensive area with the back garden backing onto the river... (This photo was taken from the CityCat) I'd say that water tank has been there since the floods a year ago. It might not even belong to the house.
Maybe it costs too much to repair but the owner can't knock it down because it is heritage listed? What a great place it must have been once.
