hi i have a 7m long 3m wide flat roof concrete garage 3m from our boundary behind which is a public footpath. We want to either knock down or extend existing to boundary to make double garage. Behind is a wooden potting shed which we would like to knock down and extend the double garage to 14m long and to boundary so we have room for storage of garden tools. Is this allowed do i need planning permission?
cheers jon
