Hi Flat Chat Mate 
Very much appreciate your input as to the relevant provisions – does this mean any concerned lot can basically stop any proposal irrespective of precedents or majority of other owners within the SP. Further how is the validity of ones argument measured – eg if one obscures 15 % or less of ones view does this equal the same level of concern as someone with a loss of 100 per cent. Further , it would be unlikely in the purchase contract that their be say a clause guaranteeing unrestricted views . Finally how does ones right to privacy and use of their own lot , precedence within the SP etc weigh up over a single lot owners concern and therefore right to veto ?? What would one see as best next steps ?
