ARCHITECTS’ DARLING AWARDS 2025
THE ARCHITECTS’ CHOICE AWARD 2025At the 15th Architects’ Darling Awards held in Celle on November 6, 2025, we at KEIMFARBEN are proud to take home the Golden Phoenix statue in the “Paints and Coatings” category.
In this event, organized by Heinze Verlag and constituting Germany’s largest industry survey, approximately 2,200 architects and planners, along with a 64-person expert media team, determined the best in the construction industry. As KEIM, not only did we reach the summit in “Paints and Coatings,” but we also crowned our sustainability vision with the Silver award won in the “Cradle-2-Cradle Challenge Award” category.
Our Head of Marketing and Innovation, Bettina Heyne, and our Sales Manager, Thomas Niedermayr, accepted the awards at the ceremony. The Golden Phoenix statues are not just awards; they are a symbol of the trust architects place in brands that turn their visions into reality.
“We are very proud to be one of the partners most preferred by architects again this year. These awards prove the value we add to our customers with our mineral-based products. The Cradle to Cradle award is a testament to our responsibility towards the environment.”

As of 2024, the number of our certified products has risen to 80, accounting for more than 85% of our global paint sales.
