The entire hallway?
Put up a pic and dimensions.I would avoid stripping back to the bricks unless the plaster is blown. Especially as you’re living in the house. I’ve stripped lime plaster walls down to brick/studs and lath and the dust goes everywhere - I once had a room I was trying to keep clean with gaffer tape around the door and a poly sheet over that, the dust traveled under the floor and up through the floorboards and coated everything.
@absurdbird Do you know what a rough cost would be to take it all back to brick and replaster? It's a hallway wall in a victorian terrace house.
