The law and what the councils try and regulate are 2 different things. The same legal tenant that gives you the right to park your car on your property theoretically applies to landing / hangaring an aircraft. The trouble is that (as I understand it) its never been tested in a court. In the absence of this local councils have all sorts of planning schemes and permits which they impose. They differ from council to council. If you run foul of your local area it will come down to how much you are prepared to spend in legal fees.
Call the council and check. Of course, all of this is only an issue if someone complains. How well do you get on with your neighbors?
