If indeed it is a type of dry stone wall... Somebody popped round a year or so ago and explained that this garden wall that goes around our rockery has a particular name - I should have made a note of it at the time, of course. He said it was an intricate, bespoke job and cost a lot to do, but knew someone local who could.
I'm interested because we need the area around our house resurfaced and that may mean taking out the wall. I'd like to be able to replace it if possible. Does anyone know the name of this intricately designed wall?
