This is the pleat herringbone design they do. I didn't charge enough labour as it took longer then I thought having to bevel every cut. Quicker then block herringbone though Is was 2/3 ply and rest concrete, had to build up a lot as builder did a crap job. Then dpm it too and then 700 over the lot.
That looks mad, I dont know why more people dont have that style! I hardly ever see that design. Maybe Im not around the posh places enough
