I live in a pre-1789 log house that was once home to the resident blacksmith on the trail west, in Maryland.
The logs were covered with clapboard siding at some point and a stick frame addition added an inside kitchen and two room upstairs.
From the outside, the only giveaway is the log smokehouse/summer kitchen.
There are quite a few log houses similarly disguised in my area.
I used to know a guy who owned an old house, may have been a log cabin....he said it was a listed historical house. Forty or fifty miles west of DC in Virginia. If I remember right, he brought in electric for lighting, wood stove for heat and a gas cooker.
A jack of all trades. He had run a Charter boat out of someplace in Florida, a pilot of cargo jets out of Baltimore, a corporate VP who apparently was hired primarily to manage a major draw-down in a major defense contractor - as soon as everyone was gone, he was fired himself.
