Looking back

and steadily moving forward

Since the founding of the Leonhard Lehmann sawmill in 1875, the heart of every venture has been the fascinating world of wood. We have seized opportunities, integrated new areas of business and continually improved and expanded our areas of expertise. In the process, we have made our companies at Erlenhof what they are today, with more than 250 employees. Our companies use the raw material in its entirety and always with sustainability in mind: after it has been used for construction, the waste timber is used as an energy source.

When it comes to the future, we are able to see the wood for the trees. Our history at a glance:
