Hi-I have owned 2 building plots in

Hi-I have owned 2 building plots in Sicily for a few years. Due to a road collapse and the commune not rebuilling the road I have been unable to build a property as intended. ! question :I have been told I have to go to the commune to find out how much land tax I owe for the past years and current year, although I have NEVER been contacted by mail, although the commune have my UK and Sicilian address/ The friend now says just pay the current year 2017.2nd Question.: I have built a temporary wooden dwelling (without utilities) that can be unbolted in a weekend. I was told by a notary I could build as many wooden houses as I liked on my land without planning permission, now a Sicilian achitect tells me I did need permission/ Can anyone help?John the Confused.
