Pergola

[sparkles2006]

My neighbour has put up and attached to his house a pergola which is roughly 6 inches on his property and 3 feet from my back window and door . He has now boarded up the sides of this pergola and put on a roof blocking my view of the parkland that I had and obviously not looking particularly pretty either . He did not inform us of any of this work .
He has attached it above his patio door and it extends 9 feet out from our adjoined houses .
What if anything can be done to make him move it over so it does not interfere with my line of sight or blocking out any light please ???.

It might count as a Temporary structure but I would photograph it and go and see the building reg people at the local council.
