Backyard privacy fence built over a retaining wall

The idea here was simple: close in a residential backyard with a wooden privacy fence along the whole perimeter. What makes it interesting is the ground it had to cross, because the line runs above a stone block retaining wall and over an uneven, sloped lawn. The maker admitted the job was difficult but said it turned out alright, and judging by the finished line, that reads as fair modesty.



The construction is solid on paper. Square wooden posts were set in concrete footings, with protector sleeves wrapping the lower post sections. The panels carry trim boards top and bottom, which gives the run a framed, finished look rather than bare slats. A pneumatic nailer, air hose and compressor were on hand for the assembly, alongside a shovel, a folding stepladder and a wheelbarrow for moving earth out of the holes.



The standout detail is the diagonal lattice. Sheets of it sit beneath the lower rail, and because the panels step down the slope, the lattice bridges the gaps that would otherwise open up along the graded ground. It lets the fence follow the terrain instead of fighting it, and the line wraps fully around the yard, running past a brick house, a detached garage and a raised wooden deck.



One trade-off seems worth naming as my own view: a wooden build like this looks like it will ask for staining every two years to stay in good shape. There is also an unanswered question about whether the neighbours wanted one side stepped and the other sloped, which would be interesting to hear more about.


The post treatment is the choice that stands out to me. Concrete footings under square posts, with sleeves wrapping the lower sections, seems like a sensible way to keep ground moisture away from the wood. The maker also clarified that the black on the posts is tar rather than bases, which is a detail I appreciate being upfront about.

One concrete improvement for this build: hardware cloth could go in while the bottom is dug out, to stop animals digging under the fence. Since the lattice already closes the gaps beneath the lower rail on the slope, adding mesh at ground level seems like it would complete the barrier for very little extra effort.
