What are the advantages of hybrid timber construction?
Hybrid timber construction combines the load-bearing capacity of concrete or steel with the ecological and design advantages of wood. It enables shorter construction times, a pleasant indoor climate, and a better CO₂ balance. Furthermore, timber facades can be designed in a variety of architectural styles.
How does collaboration with a project developer work?
