second of all, you were posting from this link

and now I see why you didn't give the link, because the section you skipped
"anch style homes are one-story houses with an open and casual layout. The shape of the house is either rectangular or an "L" or "U" shape.
The houses have low-pitched roofs and extended eaves. They also usually have an attached garage and a large picture window facing the street.
Other typical features include post and beam ceilings and sliding glass doors.
Many ranch homes (also called ramblers or California ranches) are built on a concrete slab,
though some have a basement or crawl space. Ranch homes built in the 1950s and 1960s averaged 1,300 square feet, and commonly had three bedrooms and one bathroom. Ranches built after the 1970s are typically larger.
You can find ramblers everywhere throughout the U.S., although they are less prevalent on the East Coast."
