"the blue way" 

We think and act sustainably and holistically. In doing so, we take all facets of sustainability into account. Economy, ecology and functionality are inseparable for us. 
We call this basic principle ‘the blue way’. It pervades our entire company – internally and externally.
‘the blue way’ combines reason and emotion. Stringent, goal-oriented processes that allow space for creative freedom. In our projects, we always include the creative right hemisphere of the brain and the rational left hemisphere. This results in holistic thinking.
