Log house building has a long history and the oldest log houses in Scandinavia are 800 years old. A special type of wood is the secret behind the longevity of these grand old wooden houses – northern slow-growth pine. Kontio houses are made from the same special kind of wood – Kontio Arctic Pine™. This grows close to the Arctic Circle in the clean forests of Northern Finland and its slow growth maximises the amount of extremely durable heartwood in every log. Arctic pine heartwood is far more durable than that found in southern trees and in species like spruce.
Kontio Heartwood™ also contains natural antibacterial and antimicrobial substances. In a growing tree these give it resistance to moisture, fungi and insects. The same substances also protect the wood used in Kontio log houses. This is especially important in locations with changeable weather conditions and high levels of rain and humidity. Kontio log houses are made to last generations and to continue our legacy of building extremely durable wooden houses in modern way.
Mustio Manor (Mustion Linna in Finnish, Svartå Slott in Swedish) was built in the 1780s in Southern Finland and it is a wonderful example of a long-lasting log house. It was built by a nobleman from massive wood on his doctor's recommendation. Guests who have stayed in the Manor include aristocrats, artists, composers, and members of the Swedish Royal family. The building is still in excellent condition and today operates as a museum.
