Sorry if my sketch isn't clear, yes I was intending to have insulation on all four walls. Because the garage is so narrow I was just going to fix insulation with plasterboard already stuck on it (I don't know what it's called) straight onto the long side walls.
Hi, I am doing a conversion and I'm unsure how to do new internal skin block / brickwork, Should it join onto existing walls or be kind of floating? It would obviously have wall ties to outer skin which would be using wall starters. Please see diagram.
