tømmerhus

A tømmerhus is a house built predominantly from logs, a traditional timber-building method widely used in Norway and other Nordic countries. The term comes from tømmer, meaning timber or log. Typical tømmerhus use horizontal logs that are interlocked at the corners with notches, creating a solid wall. Variants include houses built with round logs or with squared, machine-cut timbers, sometimes referred to as laftet or laftet hus in local terminology.

Construction generally involves felled logs that are peeled and dried, then laid in courses. Corners are interlocked using notches such as saddle or dovetail styles to create stability. The spaces between logs are sealed with chinking or mortar to keep out drafts and moisture. Foundations are usually stone or masonry, and roofs are timber-framed with steep pitches to shed snow. Interiors may leave the logs exposed or cover them with paneling or plaster.

Historically, tømmerhus were common in rural areas of Norway, Sweden, and Finland, built to take advantage of readily available timber and the region’s cold climate. Thick log walls provide good thermal mass, while large timber elements give a rustic aesthetic. In modern practice, traditional forms are maintained for cultural heritage, while new tømmerhus may incorporate contemporary insulation, moisture barriers, and building codes.

Advantages include natural insulation, use of renewable materials, and a distinctive regional character. Limitations can include susceptibility to moisture if not properly maintained, seasonal settling of logs, and higher maintenance for chinking and finish. Modern variants often combine traditional log walls with modern framing or insulated panels to meet current efficiency standards.

Maintenance focuses on protecting wood from moisture and pests, re-sealing or re-chinking gaps, checking for cracks or rot, and keeping the roof and drainage systems in good condition. Preservation of historic examples remains an important aspect of Nordic architectural heritage.
