As a leading timber industry and timber construction company, Blumer Lehmann harnesses the potential of timber in all its facets and works to advance timber engineering internationally. More than 500 employees work at the headquarters in Gossau, St Gallen, at locations in Switzerland, Austria, Germany and Luxembourg, and on assignments around the world on a wide variety of customer projects.

The complete timber life cycle

A fascination with wood has defined how we think and act as a business since 1875. Blumer Lehmann processes the natural raw material that is timber into innovative products, services and structures in a complete cycle of sustainable value creation. Each year in our sawing, planing and finger-jointing facilities, we turn 170,000 m³ of Swiss logs into an extensive range of sawn timber products for the construction industry.

The residual timber is processed into animal litter and carbon-neutral pellets and used as an energy source for our own power plant. Using timber construction methods, Blumer Lehmann develops, plans, produces and delivers new builds – including Free Form projects in collaboration with world-renowned architectural practices – as well as conversions with additional storeys and renovations. Furthermore, the company develops and manufactures modular timber structures that make affordable residential space and maximum flexibility possible, even when space is limited. Blumer Lehmann also specialises in silos and facilities for road and winter maintenance across Europe – automated and equipped with modern conveyor technology.

In collaboration with internationally renowned architects such as Foster + Partners, Shigeru Ban Architects and Herzog & de Meuron, Blumer Lehmann completes pioneering timber structures all over the world. 

Another specialism is modular and temporary structures. Standardised modular room concepts are used to construct schools, office blocks, residential complexes and other buildings.

Timber industry

Timber products, pellets, energy

In its own sawmill, Blumer Lehmann, annually processes around 170 000 m3 of logs from the forests within a radius of about 100 kilometres around Erlenhof. We use this wood to manufacture a wide range of timber products. We process the residual timber into pellets and briquettes or use it as fuel in our wood power plant to generate heat and energy.
