This is the style of log cabin I would use in my model.
See where the log timbers lay on top of each other rather than having a traditional gap between the logs. You can see the carpenter using a draw knife to cut an angle on each corner of the timber starting at the 0930 time mark. You can see the bevel cut through out the video on the outside of the cabin. You can see the bevel plainly at the 1128 time mark.
I may build a log cabin model to start with that is small like in the video. I would build the model so the roof can be removed to have access to the inside. If I was building a two story model I would have the roof section removable and the the second story removable for access to the first floor.
Would be a great doll house for the child in a grown up. A strong enough child should be able to lift off the sections. Would not be like a traditional doll house with one side open.
