About us

We build interiors. Since 1964. 
As a family-run enterprise, we come from a background of craftsmanship and we grow through new challenges. From experience at the construction site. From projects that can’t be solved from behind a desk. Our origin story is not just a look back, but the basis for our reliability. Today and in the future.

building dimensions is our promise and ambition. Three dimensions shape how we work: technical, organizational, and human. They explain why our projects succeed and why partnerships result from them.

Our values
Interior fit-outs are successful when everyone works together – and one party takes responsibility. That’s where we come in.
