These houses were designed by Norwegian Log and have a solid log/timber frame construction. Our logs are dip-treated with preservative to a high standard to give an indefinite life span with only minimal maintenance. The construction method, using special fully interlocking jointing, has been proven in the harsh Norwegian climate to be strong and durable. Compared with many other materials and construction methods, this means lower running costs. It also helps to preserve the value of your building as an asset.
