Scattered information about cordwood masonry was gathered from different sources such as books, professional articles, popular articles and websites. Historical cordwood masonry construction techniques and newer cordwood masonry construction techniques were included. Current teachings of ecological construction practices were added, and private and professional individuals’ knowledge. Three main cordwood wall types were evaluated and the wall type - single log with centered insulation space - was found to be optimal. Spruce (Picea abies) was identified as the best suited tree species in Norway. Mixing of clay based mortar was explained. Load bearing can be done with post framework, or the cordwood walls themselves can be load bearing. Solutions for stabilising corners were found. It is optional to clad the house or leave it unclad. Momentums for future scientific research were pointed out, such as finding thermal transmittance U (W/m2K) for woods and mortars, and understanding humidity transportation efficiency in different types of wood with/without cladding. Unanswered questions were set forth. This is a pre-scientific literature study.
