logwall

A logwall is a wall built from logs that are laid horizontally and interlocked at the corners to form a load-bearing structure. In traditional construction, log walls may use full-round logs or squared timbers, sometimes finished with bark retention or a chinking material to seal gaps.

Construction relies on interlocking notches that transfer weight and resist movement. Common notches include saddle, dovetail, and Scandinavian variants, which interlock at wall corners. Logs are typically stacked with careful alignment to create a continuous, continuous-load bearing surface, while chinking or caulking fills gaps between logs to improve airtightness and weather resistance. In some modern applications, log posts or panels may be combined with timber-frame techniques or log veneer for aesthetic or performance reasons.

Historically, log walls developed in regions with abundant timber, including parts of Scandinavia, Russia, the Baltic states, and the North American frontier. They became prominent in boreal and mountainous areas where readily available timber supported rapid, energy-efficient construction. Today they remain a characteristic feature of rustic architecture and are used in residential, commercial, and cultural buildings.

Advantages of log walls include thermal mass, natural insulation in certain configurations, and distinctive aesthetics. They can be quick to erect when logs are prepared in advance. Limitations include settling and shrinkage over time, potential moisture-related issues, and ongoing maintenance to seal joints and protect against pests. Modern practice often combines log walls with engineered components to improve performance while preserving the traditional appearance.
