I think it depends if your house is considered of historic interest or in a protected area. Even the non moveable buildings could be "re-aligned" to obtain the optimum orientation, unless some of the structure was to be preserved.

We were also advised that one is usually allowed to increase a footprint for "hygenic purposes", i.e. bathroom & toilet, if it doesn't have one, or add in the size of any (non abusivo) outbuildings that you plan to demolish.

My advice is to ask the local geometre, and then ask another one and see if you get the same answer. It will help if you have the particelle & folio numbers of your property with you & and a copy of the catastrale map with your house on it.
Otherwise a really good description of the location & the names of your immediate neighbours will help.
