Hi I'm looking at putting up a fence at the front. Does anyone know if council approval is needed for that? I've heard about blue boards, but how durable are they? There're road noises at where I am, so I was hoping to use something that could help block out some of them. Would it be a good idea to use blue boards pillars + base and colorbond infills? Like below, except with colorbond: My feeling is that, with less blue board and more colorbond, there should be less chance of cracking? Thanks for the help in advance.
