It does seem a lot of fuss about nothing.
Oh dear! Trees! Oh s**t! Survey on desk! Trees not a problem! Stop the clock! Reconsult the neighbours and the parish council! Show them the pretty trees! How interesting! Are they a problem? No!.........
I also work in a public organisation. There's a lot of stuff that gets done 'because that's what the rules say' which actually cause hold ups and problems and don't serve any purpose. I guess I'm strugglign with the 'not serving any purpose'
Have a rant at your stupid lying lazy architect, don't keep bleating on here then! Threaten to lodge a formal complaint with the RIBA (assuming he's registered) and watch him squirm!
