The first Edition of Timber Arch.

The collection of KLH projects presenting modern, individual timber construction architecture and the versatility of wood as a building material.

What is the best way to present modern, individual timber construction architecture and the versatility of wood as a building material?

That was the fundamental question in the creation of „Timber Arch Vol 01“ and the answer is simple. These are the completed projects that confirm the potential of massive timber construction – technically, ecologically, economically and, above all, creatively.

2nd KLH
CLT FACTORY

In 2019 KLH Massivholz Wiesenau GmbH has started building of new cross laminated timber plant in Wolfsberg in Carinthia (Austria). The commissioning of the plant with an annual capacity of around 150,000 m³ in the final expansion stage is planned for mid-2020.

This project is co-financed by the ERDF European Regional Development Fund.
 
 
The latest production technology used in the new plant will safeguard the competitiveness and market share of the Johann Offner Group in the field of cross laminated timber, increase the degree of prefabrication of the cross laminated timber produced and create up to 83 new jobs in the structurally weak Wolfsberg region.
