Ooh - good idea :)
There was a house up the road that dug out a new drive in the front that I am fairly sure involved digging into a 2-3' bank. I'll see if they bothered with a PP application - and if so how it read.
And I will certainly have a look for what you suggested - it's free to search.
I will keep looking in other parishes for any PPs applying to landscaping only.
