Under permitted development rules there are clear defined guidelines for side and rear extensions. Front extensions are normally NOT allowed, except where the dwelling does not front a highway or is a substantial distance from the highway.
Our local planning dept has refused our application quoting in their opinion we are not a substantial distance from the highway. Substantial is ambiguous and every planning officer in every planning dept can interpret substantial to be any distance.
Before 2008 planning had a defined measurement of 20 metres from the highway. After that the English planning portal states ‘The distance between a house and the highway in cases where that distance is substantial, it is unlikely that a building can said to front the highway’ (planningportal.gov.uk). However, the Scottish planning portal is very clearly defined as 30Mts as substantial
We found an appeal that was successful because the dwelling could not be seen from the highway. Our annexe is behind a house, is 40 metres from the highway and can not be seen from the highway.
The majority of houses in our area are approx. 10 metres from the highway. Some new build are so close to the highway that there is not enough space to park a car. Therefore isn’t 40 metres substantial?
Although irrelevant, we would like to build just 4.5 metres to the front, meaning we will still be over 35 metres from the highway.
Does anyone have any advice?
