This old wall has been repaired in the past but there was a large section missing and had become insecure for children and pets. Also a tree root had damaged it and opened up the footing.
I have repaired it as sympathetically as I can, following the same construction methods I could see from the old broken sections. We sourced some old clay bricks and flint cobbolds from reclamation yards.
Once the repair has had a while to weather-in it should blend in nicely.
