In a log house, what is the purpose of notching?

• A. To interlock logs at corners for stability.
• B. To attach a gutter.
• C. To decorate the exterior.
• D. To create ventilation channels.

Answer: (A)

Notching in log construction creates interlocking corners that lock the logs together and keep the wall stable. By shaping the ends of each log so they fit into the log below or beside it, the joints transfer loads, resist outward spread, and help the wall stay plumb as the logs settle and shrink over time. This built-in locking system reduces movement and maintains a solid, continuous appearance and structure without relying on extra fasteners. Notches also help seal corners when chinking is added, improving overall tightness against drafts. Notching isn’t about attaching gutters, decoration, or ventilation channels, which is why those options don’t fit.
