Haha, ours was built in 1945, and we're pretty sure it is two Sears kits put together. Halfway down the hall is a little 1" jog where the two pieces don't quite meet accurately.Yup, that's where the term "Craftsman House" came from. The house we sold in Portland predated those but it was also a house that a bunch of guys just got together and built. In our case, that meant no two doors were the same size.
Oh well, all the utilities are recent, it suits our needs for just the two of us, and the property it sits on is perfect.
