As a kid, we went to visit our neighbours in the country. Most people lived in the kitchen or large food prep area but had a parlour for important visitors. I remember being in a parlour one afternoon and slapping the upholstered arm of the large chair and the sunlight caught all the dust that arose from it. Never looked at upholstered chairs the same way again.
Tradd, we owned a house similar to the one you noted - a compact story and a half, with two large bedrooms upstairs with shag, two small BR on the ground floor (guest room and sewing room), one bath, modest LR and large kitchen with great counter space and full concrete basement for water pump, furnace etc. I loved that design for its efficiency, convenience, ease of cleaning and heating. If all the world went back to that design, it would make a lot of sense for all ages and abilities.
