This is a classic example of a single storey American Ranch Style house typically ordered from a catalog in the 1950s. They were inexpensive, 2-3 bedroom, 1 bath, single family dwellings. Often called tract homes, it was not unusual for there to be many in a single new subdivision. Young families could choose their new home from a catalog of 20 - 30 floor plans. Developers could use common materials across all of the plans. There are still many, many thousands of these homes in suburbs all across America - though most have been modified over the years since they were quite small to begin with. The concept was not unique to America - many developing cities around the world, where space was available, adopted similar planning with styling changes to suit local tastes.
