What type of log building is characterized by contours along its length?

The type of log building characterized by contours along its length is the full scribe method. In full scribe log construction, each log is carefully shaped to fit with adjacent logs, allowing for the natural contours and curves of the logs to be maintained. This technique emphasizes not only structural integrity but also aesthetic appeal, as the natural beauty of the logs can be prominently displayed.

When logs are embraced in this manner, they form snug joints that can help in minimizing air and water infiltration, thereby enhancing the building's insulation properties. The full scribe method also allows for settling over time, as the logs can shift slightly without compromising the overall stability of the structure.

Other building methods like half scribe or flat scribe involve less contouring and focus more on fitting the logs in a more straightforward manner, lacking the curvature that defines full scribe construction. Round logs, while they may also be used in log building, do not specifically denote a method involving contours like the full scribe technique does.
