GRAFT was developed rapidly by Arup’s Product Design

team, working closely with the Zumtobel development team in

Austria. Our CAD/CAM tools, global network of specialists and

manufacturing knowledge brought the product to market in just eleven months.

“Working together with Arup gave us the feeling that we doing more than just fulfilling

the requirements of a design brief. The multi-disciplinary team enriched the

development process with application knowledge, innovative ideas and active

feedback from a genuinely global network. The end result is a leading product that

meets both the Arup and Zumtobel standards for delivering genuine customer

benefits through innovation and application-led design excellence.”

We drew on Arup and Zumtobel experience to develop the product and bring GRAFT to market, offering a range of product design, idea generation, global product evaluation and development techniques.

This process encouraged innovative thinking, better product performance, creativity and collaboration to shape a better product.
