Home owners are now permitted to extend their homes up to 8 metres (single storey only) without planning permission, however planning drawings will still be required for consultation with neighbours, via the council. The neighbour will then have 21 days to object.
Should the council or neighbour object, the homeowner can make an appeal or submit a formal planning application.
As you would expect, these new rules do not apply to Conservation or AONB Areas
AONB – Areas of Outstanding Natural Beauty
