I understand its p.d if the floor area is under 3m as you say. The porch will be at the front of the house 3m away from the highway but only 0.5m from next door. It say p.d is granted as long as it doesnt fall into one of 3 rules. My issue is the 3rd rule
No part of porch to be within 2 metres of any boundary that fronts a highway.
It the only shows an arrow of 2m to the highway not to nexts doors boundary. The other thought is i have a porch canopy. Well when u look at the definition of a porch its:
A covered platform, usually having a separate roof, at an entrance to a building
Well does that mean i technically have a porch as it fits in the defintion it just doesnt have walls so adding walls wouldnt matter??
