Did he actually ever submit a planning application?
from reading that wee story, it doesn't mention it.
If he undertook such a project without requesting permission then sod him. However, beofre the bulldozers move in, surely he can submit and have a planning application considered - it may well be granted.
Or if he has applied and been refused, the decision could be appealed?
Or if he has appealed and still been refused, then serves him right for trying to be a smart arse and building it.
Until i know a wee bit more on the story, i'll reserve judgement on who is in the right/wrong here.
(though i bet the planners are twats as well!! LOL)
