Garage conversion wall design

[DIYMike]

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.

The sketch shows no insulation to the exposed side wall. Is this the intention?

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.

Why not do the internal structure in timber frame? The brickwork connecting to the outside wall will be a huge cold bridge.
