The cross laminated timber (CLT) plant, which has been planned by the Austrian Johann Offner Holzindustrie for some time, is being built on the site of the former RZ Holzindustrie in Wiesenau near Bad St. Leonhard. The construction of the CLT plant at Offner's headquarters in Wolfsberg, which was planned as an alternative to Wiesenau, failed due to difficulties with the approval. The potential site was in a flood zone and there is a deep well on the site.
According to a report in the "Kleine Zeitung", construction work is to begin in the course of the first quarter of 2019, with commissioning scheduled for 2020. An annual capacity of 150,000 m³ is planned for the final expansion. Together with KLH Massivholz (KLH) based in Katsch/Mur, in which Offner has held a majority stake since 2012, the CLT-capacity within the Offner group of companies would more than double. The investment sum is expected to be in the double-digit million range, and around 100 new jobs are to be created.
The campus in Wiesenau was taken over by Offner in 2016 due to insolvency.
