Attaching a fence/screen to the top of a wall with stone "battlements" on it!

Offer to clad the back of the neighbour's lean-to in shiplap?

High high is that horrible structure? That close to the boundary it will need PP if above 3m.

oof in next door's yard. These photos show where it needs to go.

ether, about 80cm long (tall) made of Tanalised decking boards and that's b een accepted.

pieces at the top and bottom between the posts to which the decking panels will be attached.

want it entirely separate from the structure that's already there on the o ther side of the wall and the surface of the decking boards needs to be not too far back from the surface of the wall on this side.

FWIW the top is the weakest part of a wall to fix to.

I think I'll probably end up going for trellis attached to posts fixed to the face of the wall, with some artificial climbing plants.

This will be lighter, will attach to the stronger part of the wall and will let the wind pass through

To look right, I think the trellis should probably start at ground level. That's obviously a personal matter of taste, but I'd discuss it with the property owner. (Or is that you?)

Not sure about artificial plants. If you use decent supports running the full height of the wall and fixed to it all the way up, I don't see the weight of Honeysuckle, say, as being a problem. Not ivy, though!

The trellis should possibly be detachable, so the wall can be painted occasionally.

Yup. Mate had new fences put up a couple of years ago (about 2 metre high). Expensive job with brick sleeper walls and brick pillars between the wood panels. Looked very good indeed.

One side got blown down in the wind a few months ago, so they re-built using steel reinforcement to the brick pillars. Other side got blown down recently.
