Hi we live on a steep hill and my neighbours house on the left ( looking at the front of the house is set about a metre higher than mine. He has decided to make some extensive amendments internally to his house which includes french windows to the rear of the property. He has now proceeded to build decking which is approx 1.5 meters higher than my garden. we are in process of building a fence to the highest statory height but my neighbours will still have a unblocked view of my garden
Does he 1) require planning permission and 2) what are my rights re privacy.
