Building something for crawlers to grow on top of brick wall

[Muso1981]

Hi,

I'm hoping someone can advise me. I've got a brick wall which used to have razor wire on top of it (left by previous owners). Anyway I took the razor wire down and I'd like to put something else up there so that crawler plants can grow across it.
I've looked at the possibility of attaching trellis us there, but this isn't a very cheap option and a bit of a pain to do. I'd also like to have something very low impact as to not upset the neighbors. Another option I had looked at was putting some vine eyes up there and running a steel cable between them but the only vine eyes I can find are very short.

Any ideas would be greatly appreciated.

Thanks,

Can I request this topic be moved to building as perhaps that would be the better location for it please?

Many thanks
