It is a nightmare job tbh . The walls are having bellies on each one. Levelling the walls will be difficult, if not impossible. First assessment it will need verge trims under the facia. Extension is eml over ply. Access is with full compliance with the whole picture. Can’t be bothered now to download the pictures from my camera, but the wall above is bare brick.... with pure cement and water patches. And on the top of that it’s a lime job.Told the customer I’ll give him quote for the render and hacking off , but in my opinion he has to rebuild that wall in sections, supporting it with first. He wasn’t very keen on that , but I told him he doesn’t have a choice. I can literally pull the bricks with my hand. The domestic kingdom is a quite an eye opener eh?
