When she did her house tour of the old house the dressing room was on the ground floor, its opposite the front door as you come in. She spoke about this and showed it in the tour.. don’t need to have been to her house
to know that.
She spoke about how the main living space (kitchen, diner, lounge was in the basement). They then had a more formal living room and piano room (basically 1 room as knocked through) on the ground floor. This is also where they hanged all their coats so if was kinda a gloriefied entryway and she said they didnt use the room much. They spent most of their time in the basement.
In my opinion the new house has a much better layout. Not nearly as nice location but slightly bigger, an actual garden instead of a courtyard too.
