It is now quite common to see a lattice section added to the top of a standard paling fence. When we build this type of fence we raise the top rail so that is flush with the top of the palings. We extend the height of the posts a further 600mm and we add an additional rail to the top height of the posts then the lattice is added to the fence. This can increase the height anywhere from 2.5mtrs to 3mtrs. The type of fence does come with varying permit requirements so we recommend further investigation occur to you local council to establish the requirements in your area.
