A wee bit of history here for the Appalachians....
I found this quite interesting, as here are pics of my forefather's house. Late 30's, early 40's, or perhaps a lot earlier.

( Despite my long interest in log cabins, much of the following is from an article from Jim " Crow" Smith. Fits the region better).
Even though multiple cultures drifted west following immigration due to the more eastern lands being well occupied , cabins ( and other structures) were in the Smoky Mountains usually hewn square logs. Despite the greater labor of squaring all sides. And pre chestnut blight there being a agreeable to work medium aside; the precious greater labor was still required.
Chimblys often followed a common to a culture masonry ,the expense of an iron blacksmith made lintel was not uncommon despite again the multiple cultures....While cultures were very different in origins it is interesting to note some of the commonality of a harsh region with tough sinewed people populating it. Networking ,yet keeping their own traditions.
A type of notching cabin log ends has been noted as not being seen as much elsewhere. Notching requires water having a place to go ,rather than stand , and can hold logs tighter too. I'd need to look it up ,but the unique notching had a near flat top ( though a slant to one side) and a dovetail bottom (?).
Small cabins were the norm with several people in a single room. Maybe in time the luxury of an addition ....Tradition shows in how an addition and it ' s type came into being.
Windows were small if even more than a " granny hole" to peek through.
Honest cultures ,but not casting aside traditions simply because life was now in America( among the Scots for one) could create a life for a life scenario and sitting near a window at night might make someone a big target.
Later windows became larger , or modified on older structures. Siding added to some , ect.
Them old cabins have much to tell. Many were razed when the Smokies became a park though.
