The architecture is simple, very practical.
While the length and size of available logs limited the size of a pioneer’s cabin, you could more than double the space and house two families in a dogtrot. (I love that name.)
This looks like ideal housing for a pair of married brothers. (Or another pairing.) Each family would have a fireplace and a large room. Table and kitchen equipment on one side. Put the bed in a corner with a cradle for the baby and trundle for an older child. You may have room for a rocking chair.
Your relative, or business partner, is only a breezeway away. Bonus: the breezeway acts as a covered porch for both families. I can picture the line of heavy boots, or wooden shoes, beside the door. I wonder if the dog used it as shelter to give meaning to the name?
Like many homes, I’ve also seen these cabins where only one side had a fireplace. As the family grew, they built the second portion for sleeping rooms. Brrr when your feet touched even a rag rug on a January morning.
In the sweet romance NEW DREAMS, one of these cabins falls victim to a cyclone. That day was truly terrifying for the recent immigrants. Check the details here: https://amzn.to/3vWydWE
