Hi, I’m looking to remove a fence between my house (privately owned) and my council neighbour. From the pavement the fence is approx 4 ft high and would be looking to replace this with a 3ft wall until it reaches my building. I then wish to raise the wall height to 6ft along the rest of the length of my driveway to the end of the house. I understand I need a building warrant for the 6ft wall however if I continue with the 3ft wall but add fencing on top of that (to bring the height to 6ft) would that negate the need for the building warrant? Also, if we made a carport from the side of the building and attached it to the wall then added doors at the front (currently 6ft gates) and back, would this be allowed? Many thanks.
