I recall a TV show from years ago, called 'Pioneer family' or similar. Set in the US, it was a reality show where applicants set off for The Frontier, possibly Montana, in wagon trains, rigged out lice C18 pioneer families; they arrived and had x months to 'set up house' (build a cabin) before winter arrived, and were judged on their efforts.
There were a few families taking part, who, in the cabin, lived what we would call 'on top of each other', all going to bed at the same time in one big, 'attic' bedroom, and otherwise all living together and interacting together.
FFWD to the 'reflections' episode, once they were back home.
One was the 2 or 3 child family of a successful business exec and his working wife. The eldest teenage girl, 'typical' 15 year old Californian girl- was interviewed, alongside the others, of course.
She said how weird it was living in such a huge house, how you never knew who was in and who was out, how quiet it was, how disconnected she felt from the family's life, having been thrust up close and personal for the few months of the show.
My other thoughts turn to big Queensland houses, where the EAs run out of words to describe the more or less identical rooms. Family room. Lounge. Retreat. Games room. Playroom. Cinema room. And so forth.
We had several friends who didn't venture into half their rooms! But at least didn't have to heat them. And others with, like, a playroom where the DC could leave it looking like a bomb had gone off in a Lego factory, as they just shut the door on it of an evening (and where, a bit sadly, a child had played alone, all day). But those DC never learned to tidy up because they didn't have to.
Which parent is really going to ensure the playroom is all put away at night. Then the lounge. Then the snug. etc, etc?
Right now I want one extra room to set up my sewing machine and painting stuff as DH is now WFH in that 4th bedroom.
