I have a client whose house fronts Road 'A', there is a front door and the propertry looks like this is the front. The address of the property is Street 'B' , along the rear of the property. The front is about 1.2m back from the rear of the footpath of Street 'A' and the rear has a driveway coming off of Street 'B' with an inegral garage. The letter box is on the door to Street 'B' My client wants to extend 3.5m towards Street 'B'. I am not sure whether this would be classed as a front extension and therefore refused fro being larger than 1.2m (as prescribed in planning guidance) or, whether it would be classed as a rear extensnio because that is what it looks like? Has anyone had any experience? I don't want my client ot incur any costs as i think i should know the answer but have never come across this before...
