Thanks for the reply. Not a retaining wall and piers will be symemetrical - either side

Hi looking for advice please landscape building a curved wall with piers outside to go around a patio agreed width is 400mm as it will be used to sit on also with some flat coping stones. my plan was a half-brick skin either side with a 200mm void. could I use brick ties to hang over into the cavity and infill with a dry mix of concrete - is this too much, what would be your advice please also does the wall have to be built into the piers so the bricks overlap into the piers and would I need to use ties or could the piers be freestanding with ties and tie the wall into the piers? thanks In advance
