There's a subdivision a couple blocks from me that was built in 1955/1956. I used to hear people refer to them as the "Ohio Homes", which I think was the developer of the area. It seems like the houses themselves were manufactured by National Homes. None of them originally had garages, some had carports. Interiors were somewhat spartan - some didn't even have finished ceilings. I had several classmates in elementary school that lived in them, and most of the families went on to build much nicer homes in a few years. Most of the structures still exist, with many totally renovated and expanded. A couple have been destroyed by fire, and three or four were destroyed or heavily damaged in the explosion of a house on the next street over back in the early 1970's.
