I want to raise the height of my side fence by a small amount (max 30cm or so) to hide a bit more of the view of the neighbouring house. It is a colourbong corrugated fence with a metal capping. The fence is double sided, eg looks the same on both our side and the neighbours', with metal capping approx 10cm wide that runs the entire length of the fence. Regarding the look, I like the idea of slats but am open to anything that works.
Thanks for any advice.
front face - back looks the same
