my grandmother used to refer to the front room as the parlour.
(See I may not be posh but came from stock that thought they were

)
My dad's mum had the "big" house in their stair up the South side.
Most of them were "single ends", hers had an indoor, unshared lavvy, also a freezing cold "parlour "that was used on high days and holidays, otherwise the fire was never lit in that room.
The main living area was the kitchen, with a range cooker which always seemed to be on , sink, coal cupboard, big sideboard armchairs, and they had a bed in there ,
