It depends what we find underneath, it's had the front bay taken out so I imagine it's a horror show under there. Ideally we'll leave the brick but if not then perhaps lime render. It's the front, side and back so too much for me to take on... Were you able to chisel that off? It looks thick enough to get underneath it?

Our house was built in '58 and they obviously knew they were going to render the top half because the underlying brick laying is 'functional'. The render is about 12mm thick, where the weather had ingressed it flew off, further up it was stuck like shit to a blanket. It'll do more damage to attempt to remove than making good. Used a chisel in the Sds drill, you could just hammer and chisel it but having a spare hand to catch the debris is useful.

Sounds like you want a bare brick finish then? Maybe a gentle sandblasting.
We had a lintel replaced that had failed and crazed the render over the years, I've taken it back to brick with a little damage but tomorrow I pick up the scaffold so I can have a crack at re-doing.
