We select the best trees for log construction individually and leave the rest in the forest to grow.

Even in the olden times, it was a well-known fact that the best time for logging is January and February. The tree is always cut from the base that we often have to dig out from the snow by hand.

A loggers expertise is weighed in the planning of the falling direction of the tree and in whether the large tree falls where the logger wishes it to fall.

After logging, we trim the tree or cut off all branches.

We cut the branchless trunk into the size required by the building constructed. The longest logs can be as long as 12–13 metres and the shortest three metres.

Finally, we transport the trees out of the forest. We sometimes have to pull the trees closer to the transportation vehicles using wires.

We peel the bark off the trunks by hand. Peeling one over 13-metre-long log takes about an hour and plenty of sweat.

We use the sawmill to cut off the “cheeks" on two sides of the round trunk making the trunk angular. We sell the high-quality boards created in the sawing process for, for example, carpenter building material.

After sawing, we store the logs and let them dry, without using a machine, for about a year.

On each log, we draw a shape based on the bottom log, using a pair of compasses. Thus, each log gets a natural and compatible shape.

We carve the logs using a chain saw according to the lines drawn on them so that each log fits perfectly on the lower log.

When the logs have been stacked as a wall, we hew their surfaces. Thus the log gets a beautiful finishing and the wood fibres are blocked, which makes the log durable.

A house or a sauna built out of log lasts from one generation to another.
