My West Country born grannie had a kitchen, scullery and two front rooms. The kitchen was where her and grandad spent their time watching TV, eating meals, and where we sat when visiting. The scullery leading off it was where she cooked and washed up.
The front room to one side of the hall had the "posh* three piece, cabinet etc. I don't ever remember going in there. The room on the other side of the hall I assume was a formal dining room. The door was permanently shut 
Did you think you were poor growing up?
Has anyone played That’s Not My Neighbor? Surprisingly tense little game




She was in service, perhaps that might be something to do with it?
although we do use the 'front room' every day (which is at the back incidentally).
