My neighbour (should I say, the landlord of my neighbour) has told me she will not demolish her boundary wall, or allow me to attach anything to it. So I am putting a fence alongside it. Part of the fence will be supported by a deck alongside, by bolting the posts to joists. But the other part of this fence must span the back of a driveway (4 metres), with no posts into the ground (wall foundations) and no fixing to the wall alongside.
Any suggestions? I was thinking maybe 8 inch deck joists, 4.2 metres would do ths job, but I cant help but think it would end up waving about in the wind, and be hard to attach the featheredge boards to, as well as sagging (could I use diagonal braces?).
I guess I could put a post into the ground alongside the wall in a little concrete, just to take the weight of the fence. It cant go far into the ground, but maybe enough just to take some weight. I cant disturb the wall's foundations, which are brick spreaders.
