	Cordwood is a term used to describe a pile of wood that is cut into lengths of a similar size and stacked in a single row. The term can describe wood that has been stacked as a storage method for firewood, but it can also be used to describe a stack of wood used to construct a wall, often with lime mortar in between and sometimes referred to as a stackwall.

	The origins of cordwood are unclear, but structures around 1000 years old existing in Germany and other countries such as Sweden and Canada also have some tradition of employing this method. It has some advantages because it can make effective use of off-cuts and end logs, not requiring the longer timbers usually needed for framing and log construction. It is also a relatively simple and cost-effective vernacular construction method, making it popular with self-builders, and as walls often contain high quantities of mortar, it has increased thermal as well as some insulative properties. As the timbers are laid with the end grain exposed externally, the thermal properties are decreased, though this can be countered by the depth of the timbers that are used, as well as the introduction of vermiculate into the mortar mix and the potential for cavity wall construction or two layers.

−	Cordwood construction	+	Cordwood construction is a construction method that uses end-grain logs of varying lengths stacked to form walls, usually with mortar in between. In his book Essential Cordwood Building: The complete step-by-step guide (New Society Publishers, 2018; Gabriola Island, Canada), Rob Roy suggests a common mix by volume to be sand (9 parts), sawdust, and non-agricultural lime (3 parts each) with Portland cement (2 parts). As the timbers are end grain, they are likely to dry and move. The suggested mix takes some time to cure, allowing for some movement.

Cordwood is a term used to describe a pile of wood that is cut into lengths of a similar size and stacked in a single row. The term can describe wood that has been stacked as a storage method for fire wood, but also can be used to describe a stack of wood used to construct a wall, often with a lime mortar in between and sometimes referred to as a stackwall.

In the US, more specifically a full cord of wood is a stack of timber firewood lengths that is 4 foot tall, 8 foot long, and 4 foot deep (1.2 by 2.4 by 1.2 metres deep). Face chord describes the same surface area of wood stack but where the depth of the wood is only 16 inches, about a third of a full chord or less than half a metre in depth.
