This was just a way for home builders to save money by building fewer walls.
They convinced homebuyers and influencers that is trendy, that living in a house that feels like a Walmart supercenter was the thing to do.
I really don’t think many homebuyers asked for a toilet next to their living room.
IMO, some of the popular trends are fetishization of being poor. Open floor plans ≈ small apartments. Farmhouse / country style / industrial ≈ simplicity and scraping by.
