It sounds like you live in the Ginestar. I would advise you to go and discuss your problem with David Pique in Miami Playa.
I have not heard of any amnesty being given to in this area. However  " after six years it could not be demolished" I believe this is the case so long you are not in an area controlled by the Forrestals i.e forest area. If you are within forest area there is no mercy. My friend was ordered to demolish his beautiful house last week despite having permission after the forest people redrew the perimeter of their area. I am not a lawyer so better speak to Pique.
