I found bits of this fiberglass/plastic mesh that they use for plastering out in the street.
It occurred that if I cut it into lengths and mounted it using bits of match-stick and plastic as posts and painted it up it would make fair farm chain-link fencing. Here is the result - about 1.4 metres of it :) Figures for scale
Chopped up and damaged, I added joists and an partial upper floor, plus using a piece of the cut off wall I added a partial internal wall too. I then based the structure and added the rubble and scatter.
The roof section is removable
So is the upper floor
As I was digging through boxes looking for bits for this build I came across this railway buffer from Captain Jack`s Locker (a 2-part resin model), so I quickly painted it up and added some scatter to the base.
