The two unique wooden buildings, made of spruce wood and designed for children, saw the light of day in 2015 and 2018. They are protected with a Silvanolin® primer, and to increase water repellence, the wooden castles are also protected with the natural wax Silvacera®.
In the pictures you can see a nice natural ageing of the wood over the years, where the colour of the wood changes to a silvery grey shade, but this does not affect the effectiveness and quality of the wood protection.
